Golden Tiger EA v9
Parameter Guide & Settings

What every adjustable input actually does, and what happens when you raise or lower it

For version v9 | Instrument: Gold | Written by the Golden Tiger EA Team

What this document covers

This EA runs a stepped dynamic grid: when the market moves against the position it adds in stages to pull the average price closer, and the whole round is closed together. That structure suits ranging, mean-reverting markets; in a sustained one-way move the floating loss builds up as more grid orders are added. So every input you see here is really tuning the same trade-off: speed against tolerance.

No expert advisor (EA) can guarantee a profit. Trading leveraged products may result in losses exceeding your original investment; trade only with funds you can afford to lose entirely. This document is for information only and does not constitute investment advice or a solicitation.

1. The lot size is yours to decide

This is the single most important property of the system — every other input builds on it

Where the lots come fromYou type them in: the starting lot and the per-order ceiling are both absolute lot sizes. What you enter is what trades.
When the balance changesThe lots do not move — profits do not scale them up (no auto-compounding), and losses do not scale them down either. The risk ratio quietly rises as the balance shrinks; watching and adjusting it is on you.
Account currencyNo currency check — it will run on any account currency. Whether the lot size makes sense for that currency is yours to work out.
Broker lot limitsNo safeguard. If you enter more than the broker allows, the broker simply rejects the order.
The on-chart panelUses MT5 chart comments; the font size cannot be changed (the terminal controls it, not the EA).

What this means

Position sizing is entirely in your hands: how big to run, and when to scale up, are your decisions. The flip side is that the system never adjusts to your balance for you — after the account grows, coming back to raise the lots is up to you; and when the account shrinks, coming back to reduce them matters even more, because the old lot size is now oversized for the smaller account.

2. Before you start

Not parameters — but nothing runs until these are right

How to install it in MT5

  1. Get the EA file (.ex5) — provided by Support.
  2. Open MT5, choose File → Open Data Folder (top left), go into MQL5Experts, and copy the file there.
  3. Back in MT5, right-click “Expert Advisors” in the Navigator window (Ctrl+N) → Refresh.
  4. Drag the EA onto a gold chart and click OK in the settings dialog.
  5. Make sure the big “Algo Trading” button in the toolbar is switched on (green).
  6. The EA name with a green icon in the chart’s top-right corner = it is running.

Rather not do it yourself? Fill in the contact form and our team will walk you through the whole setup.

LicensingLicensed by account number and server together. Changing account or broker requires re-activation — contact Support first. Until then the chart shows a notice.
How to attachAttach it to a gold chart and enable AutoTrading in MT5. The chart timeframe does not matter — the decisions are unaffected by whichever one you pick.
One copy per chartAttach only one copy per instrument. If you run it on several instruments, make sure each copy uses different Magic Numbers.
ConnectionIt needs a stable 24-hour connection; a VPS is recommended. After a disconnection the EA rebuilds its own state automatically — nothing for you to do.

3. The on-chart panel

Learn to read the current state before you change anything

Once attached, a text panel appears in the top-left of the chart. It uses MT5 chart comments: there are no buttons, and the font size cannot be changed — the terminal controls that. From top to bottom:

Panel fieldHow to read it
StatusACTIVE = inside the trading session, a brand-new round may start; Out of Session = outside it, no round is started from scratch. The Wave figure after it is an internal wave counter — Support uses it for diagnostics; you can ignore it.
TP DistanceOne unit of target distance, derived from current market volatility. Every target multiplier is applied to this number.
Allow 1stThe permission level for a first order: the price after Buy <= means “the market must be below it before a first buy order can open”; Sell >= is the mirror image. It is one of the entry conditions, not all of them.
[ EA PARAMETERS ] blockLists every input you have set, plus the numbers they work out to (the three target distances, the floating-loss limit in money) — the fastest place to double-check after changing settings.
EA Float (3 magics)Combined floating P/L of the three modules (manual orders excluded). This is the figure the floating-loss limit watches.
[ MODULE 1 / 2 / 3 ] blocksTwo rows per module: Buy / Sell = order count | total lots | BE (average price) | TP (target for the round) | PnL (floating P/L on that side).

4. How it works

The parameters only make sense once the mechanism does

You type the lots in yourself — two numbers set the scale of a whole round

Factory settings versus the most conservative setup (grid pacing shown at the factory “new step every 2 orders, ×1.5 per step”)

Comparison Factory settingsMost conservative
Starting lotInitial Lot Size0.01 lot0.01 lot
Per-order ceilingMaximum Order Lot Size0.05 lot= 5× the starting lot0.01 lot= same as the start
Grid step-upStepped growthup to the ceilingNo growth at all
Total lots at 9 orders in a roundapprox. 0.21 lot0.09 lot
All three modules fully loaded (9 orders each)approx. 0.64 lotapprox. 0.27 lot
Size your lots from the bottom row“All three layers loaded at once” is the worst-case position size; make sure the account can carry it before choosing the starting lot.
  • “9 orders” is only an example — the actual count follows the market and has no hard cap; the last line of defence is the floating-loss limit.
  • Setting the per-order ceiling equal to the starting lot switches the step-up off — a legitimate, most-conservative setup.
  • The lots never follow the balance — whether the account grows or shrinks, adjusting them is up to you.
Fig. 1 — you type the lots in yourself: factory settings versus the most conservative setup

The row to study in this table is the bottom one: with all three modules fully loaded, the total position is roughly sixty-odd times a single starting order. There is no automatic conversion — whatever you type into Initial Lot Size is exactly where the round starts, so “can this account carry all three layers loaded at once?” is the question to settle before you type the first number.

What one round looks like (buy side shown)

Every order in a round shares one target price — they close together, not one by one

1234
Target for the round
Average price
Target reached → the whole round closes
1First order2Grid order 13Grid order 24Grid order 3 (larger size)

Four things to remember

  1. Every grid order requires the price to move a certain distance against the position first, and the cooldown timer to expire — it will not fire repeatedly at the same price.
  2. Each grid order pulls the average price closer to the market, and the target for the round moves down with it — the price does not have to climb all the way back to where the round started.
  3. The target distance is not a fixed number of points. It stretches and contracts with current market volatility: wider when volatility is high, tighter when it is low.
  4. The more grid orders there are, the larger the position and the deeper the floating loss. That is inherent to a grid structure — not a malfunction.
Fig. 2 — every order in a round shares one target and is managed and closed as one

What this chart is really about is the relationship between the two horizontal lines: the gold dashed line is the average price, the green line is the target for the round, and the target always sits on the profit side of the average. Each grid order pulls the average toward the market, and the target moves down with it — so the price never has to climb back to where the round started; the moment it touches the green line, the whole round closes together. Once that clicks, the “TP Multiplier” inputs further down will make sense.

Why grid orders keep getting bigger — the step-up and its ceiling

  • How fast it climbs is set by the per-step multiplier and the orders-per-step; where it stops is set by the per-order ceiling — all three are numbers you type in directly.
  • Lower the per-step multiplier, or raise the orders-per-step → slower growth and a gentler drawdown curve, but the average price also moves more slowly.
  • Set the per-order ceiling equal to the starting lot → no step-up at all: the most conservative setup (and it makes the two step parameters irrelevant).
Fig. 3 — how grid sizes step up, and how the ceiling holds them down

The line to study in this chart is the red dashed one: the bars climb until they touch it, then every later order stays at that height. How fast they climb is set by the per-step multiplier and the orders-per-step; where they stop is set by the per-order ceiling — the factory 0.05 is 5× the 0.01 starting lot, which means that in a deep round a single order can grow to at most five times the starting size.

The three modules run as a relay, not as three times the bet

A later module only starts once the previous one already holds a position and the market keeps moving the same way

runs the furthest

Its own grid, its own target
When all three modules hold positions, the exposure is the sum of all three layersThat usually happens in a strong one-way move. Size your lots for “all three layers loaded at once”, not for the first order alone.
  • Each module has its own Magic Number, so the three can be reconciled separately in reports and history.
  • If you run several EAs on one terminal, the numbers must not clash with each other — and the three must not be set to the same value.
  • Orders you place by hand belong to no module. The system never touches them, and they are excluded from the risk figures.
Fig. 4 — the modules form a relay, but their exposure adds up while all three hold

The part to take away from this chart is the gold reminder bar at the bottom: the modules are a relay, yes — but a relay does not mean only one runs at a time. When a one-way move goes far enough, all three modules hold positions at once, and the exposure is the sum of the three layers. So when you size your lots, use “all three layers loaded at once” as the yardstick, not “just the first order” — this is the most commonly underestimated point in this whole document.

What is deliberately not on the list

The entry logic, the distance that triggers a grid order, the cooldown timers and so on are all derived by the EA from current market conditions. They are not adjustable, and they do not change with account size. That is deliberate: it keeps your decisions focused on one question — how much risk to run.

6. Parameter by parameter

For each one: what raising it does, what lowering it does

Initial Lot Size / Maximum Order Lot Size (the lots)

numbers | factory 0.01 start / 0.05 ceiling
What they do
Initial Lot Size is the starting lot of every round; Maximum Order Lot Size is the absolute per-order ceiling. Both are lot sizes you type in directly, and the grid step-up climbs between the two (see Fig. 3). Factory 0.05 = 5× the starting lot.
Raise them
In the same market, profit and loss both scale up. The floating loss also deepens faster, so the floating-loss limit is reached sooner.
Lower them
The whole position structure gets smaller and the account survives a deeper move against it. The cost is that profit accumulates more slowly.
Two things to watch
1. They do not follow the balance. Profits do not scale them up, and losses do not scale them down — when the account shrinks, the risk ratio quietly rises, and watching for that is the single most important job left to you.
2. Think of the two numbers together. The ceiling should be at least equal to the starting lot; a ceiling below the start means the grid never grows at all (a legitimate most-conservative setup — just make sure it is not a typo).
Finding a starting point
Treat the starting lot as “the smallest order this account will ever place”, then work backwards from all three modules fully loaded to check the worst case is survivable (see the bottom row of Fig. 1). If unsure, start at the broker’s minimum lot, let it trade through a full market cycle, and only then decide whether to raise it.

Stepped Lot Multiplier (growth per step)

number | factory 1.5
What it does
How much the lot size is multiplied by on each step up. Together with the orders-per-step below, it sets the pace of growth (see Fig. 3).
Raise it
The size hits the ceiling quickly: the average price moves fast, but so does the position.
Lower it (toward 1.0)
Nearly equal-sized grid orders, a flat curve. 1.0 = no growth at all.
Do not set it to
Anything below 1.0, zero, or a negative number. Below 1 the grid orders shrink instead of averaging down; zero or negative breaks the size calculation.

Stepped Group Size (orders per step)

integer | factory 2
What it does
How many orders it takes to move up one step. At the factory value of 2, orders 1 and 2 are the same size, orders 3 and 4 step up once, and so on.
Raise it
Growth is slower and flatter, so the size of a round builds up more gently.
Lower it (e.g. 1)
Every single order steps up, reaching the ceiling as fast as possible — the most aggressive setting in this group.
Do not set it to
Never zero. It must be an integer of 1 or more.

TP Multiplier (three target distances)

number | all three factory 2.0

The target is not a fixed number of points. It is “one unit of distance derived from current volatility × the multiplier”, so it widens automatically when volatility rises and tightens when it falls. TP Distance on the panel is that unit. The three multipliers apply in different situations:

ParameterWhen it applies
TP Multiplier (1 Order)While the round still holds a single order — measured from the entry price.
TP Multiplier (>=2 Orders)Once grid orders have been added — measured from the average price instead.
TP Multiplier (Out of Session)Winding down: the session is over but positions are still open.
Raise it
Each round has to earn more before it closes, so the profit per round is bigger — but closing gets harder, positions are held longer, and more grid orders are likely.
Lower it
Faster closes, faster turnover, shorter holding times — but thinner profit per round, and spread and commission take a bigger share of it.
Note
The out-of-session multiplier is normally set equal to or slightly below the other two — the point is to clear the book, not to squeeze out more. None of the three should go below 1.0: a target too close to the entry may be rejected by the broker’s minimum-distance rule.

Trading session — it only governs whether a NEW round may start

The window is counted in whole hours of MT5 server time, not the clock on your computer

no new round
a new round may start
no new round
00:00Start (this hour included)End (this hour excluded)24:00
Inside the window

A new round starts when conditions are met

Existing positions keep adding and closing as usual

Targets use the “1 order” and “grid” multipliers

Outside the window

No new round is opened

But existing positions keep adding and extending

Targets switch to the “Out of Session” multiplier

  • Widen the window → more chances to enter, but also more entries during thin, wide-spread hours; narrow it and the opposite applies. The window only blocks a brand-new round — it never interrupts what you already hold.
  • A separate switch (factory: on) excludes the 15:00 server-time hour from the session — it only has a real effect once you widen the window to cover hour 15.
Fig. 5 — the session decides only whether a new round may start; it never abandons open positions

Start Time >= / End Time < (trading session)

integers 0–23 | factory 4 – 12 (server time)
What it does
Defines a window in whole hours of MT5 server time. The start hour is included, the end hour is excluded. Only inside that window will Module 1 open a brand-new round.
Outside the window
No new round is opened, but existing positions keep adding, keep being managed and keep closing, with targets switched to the “Out of Session” multiplier. If a running round keeps moving the same way, Modules 2 and 3 will still take over and extend it — the window blocks starting from scratch, not what you already hold.
Widen it
More chances to enter, but also more entries during thin hours when the spread is wide.
Narrow it
Trades only in the hours you approve of: fewer entries, more selective — but there may be days with no activity at all.
Do not set it to
A window that crosses midnight is not supported (e.g. 20 to 4). The start must be lower than the end, otherwise no new round is ever opened. Check how many hours your server time differs from your local time first — they are rarely the same.

Skip Hour 15 First Orders

switch | factory On
What it does
While on, the 15:00 server-time hour is excluded from the trading session — no brand-new round starts during that hour, and existing positions are managed as usual (same rules as outside the session).
Why it exists
That hour often brings liquidity hand-overs and widening spreads. The factory choice is simply to sit it out — better to trade one hour less.
When you will notice it
The factory session is 4–12, which does not include hour 15, so at factory settings it has no practical effect. It only starts blocking orders once you widen the session to cover hour 15.
Suggestion
Leave it on unless you have a specific reason. If you do want new rounds during hour 15, switch it off — but understand why the factory setting avoids it.

Module 1 / 2 / 3 Magic Number

integers | factory 11111 / 22222 / 33333
What it does
Each module stamps its own orders with one of these numbers, which is how the system recognises which positions are its own. They also let you reconcile the three separately in reports and history.
When to change them
When another EA is running on the same MT5 account, or when you attach a copy to several instruments — set the numbers so nothing clashes.
Do not set them to
The same value across the three, or to a number another EA already uses — the modules would mistake each other’s orders for their own and the risk figures would be wrong. Leave them alone unless you have a specific reason.
Worth knowing
Orders you place by hand carry none of these numbers. The system never touches them and never counts them.

Max Floating Loss % of Balance

dropdown | 10% – 90% | factory 90%

Total floating-loss control — everything closes together

The floating loss of all three modules is added up; once it reaches your chosen share of the balance, every EA position is closed

Factory setting 90%
10%20%30%40%50%60%70%80%90%
Set it low

Any single loss stays small, but an ordinary pullback can stop you out and cut short a round that would have recovered.

Set it high

The market gets more room to come back, but when it does trigger, the loss booked in one go is a large slice of the account.

How to read the number

Balance 2,000 × 90% → everything is closed once the combined floating loss reaches −1,800, then new entries pause briefly.

The factory 90% is the widest option in the dropdown — close to carrying the market with the entire account. Make sure you understand that before deciding whether to lower it.

The panel prints that amount for you — no need to work it out yourself. This is the last line of defence, not the normal way out: a round is normally closed by reaching its target.

What it does
It adds up the floating P/L of all three modules (both directions, all instruments; manual orders excluded). Once the combined floating loss reaches “balance × this percentage”, every EA position is closed immediately and new entries pause briefly.
What factory 90% means
It is the widest option in the dropdown — the market gets the maximum room to come back, which is close to carrying the move with the entire account. The flip side: when it does trigger, the account books a loss of close to ninety percent in one go. Make sure you understand and accept that before keeping the factory value.
Lower it
The largest single loss stays contained. But an ordinary pullback may stop you out, cutting short a round that averaging would have recovered — which can end up booking losses more often.
Note
This defence closes everything at once, not just the worst position. It is checked continuously and is not restricted by the trading session. Also, a gap can jump straight past the level, in which case the actual fills will differ from the figure you set.

7. Three directions you can take

Not recommended values — just which way to move

What you wantMove theseWhat you accept
More conservative
hold the drawdown down
Lower Initial Lot Size | move Maximum Order Lot Size toward the starting lot | raise Stepped Group Size | narrow the session | lower the floating-loss limit from 90%Profit accumulates proportionally more slowly, and some days there is no activity. With a lower floating-loss limit, an ordinary pullback is more likely to stop you out.
Stay at factory
run it as designed
Change nothing; set Initial Lot Size to match your account sizeThis is the pace the system was designed around. Let it trade through a full cycle before considering changes.
More aggressive
faster turnover
Raise Initial Lot Size | lower the target multipliers a little | widen the sessionThe floating loss also deepens faster and the floating-loss limit is reached sooner — the risk scales up in proportion.

Three rules for changing settings

  • Change one thing at a time. Change two and you will not know which one caused what.
  • Do not change anything while positions are open. The lot and target inputs affect how existing positions are managed — wait until the round has closed.
  • Size for the worst case. Work out your lots assuming all three modules are loaded at once, not assuming a single first order.

8. Common questions

It has been attached for hours and nothing has happened. Why?

Check Status on the panel first. Out of Session means the trading window has not arrived; ACTIVE with no orders means the entry conditions have not all lined up yet (glance at the Allow 1st row too — the price not yet crossing the first-order level is one such case). This system is selective by design — sitting flat is a normal state, not a fault.

The session is over. Why is it still placing orders?

The session only blocks a round that starts from scratch. If positions are already open and the market keeps moving the same way, grid orders and the later modules taking over are not restricted by the window — the point is not to abandon a round halfway through.

My account has grown. Do I raise the lots myself?

Yes — the system never follows the balance on its own. Whether and when to raise them is your call. The reverse matters just as much: it does not scale down when the account shrinks either, at which point the old lot size is oversized for the smaller account — remember to come back and reduce it. If you are unsure how much to adjust, contact Support and work it out together.

Why is my lot size different from my friend’s?

The lots are typed in individually, so differing is perfectly normal — everyone’s capital and risk appetite differ. Always go by the figures shown in the [ EA PARAMETERS ] block on your own panel.

What should a small account watch out for?

0.01 is already the minimum lot at most brokers, with no room below it — which means a small account inherently carries a higher effective risk share than a large one (the same three loaded layers make up a bigger slice of a small balance). Factor that in when you size it, and consider moving the per-order ceiling toward the starting lot.

Can I close one of the orders by hand?

You can, but it is not advisable. The average price and the target are calculated for the round as a whole, so removing one order makes the rest recalculate their target from a new average — the outcome may not be what you expected.

Do I have to restart after changing a parameter?

Confirming the EA properties dialog in MT5 applies the change and re-initialises the EA. Afterwards, check that the AutoTrading indicator in the chart’s top-right corner is still active, then verify the new values in the [ EA PARAMETERS ] block on the panel.

What happens if my computer shuts down or loses connection?

Every open order carries a target price held at the broker. That one sits on the server and stays valid even while the EA is not running — if the price reaches it, the order still closes. It is the last mechanism left when everything else is off.

But it freezes where it was last updated: while the EA runs, every new grid order revises the round’s target downward; with the EA down there are no new grid orders and no revisions. So if the price never comes back to that level, the position simply stays open.

On top of that, the floating-loss limit only works while the EA is running. Which is why a VPS is strongly recommended. Once the connection returns, the system detects the outage and rebuilds its own state automatically — nothing for you to do.

9. Risk disclosure

  • No expert advisor (EA) can guarantee a profit.
  • This EA uses a stepped dynamic grid structure and adds to positions in stages when the market moves against them. The structure favours ranging, mean-reverting markets; in a sustained one-way move it accumulates floating losses.
  • Trading leveraged products may result in losses exceeding your original investment. Trade only with funds you can afford to lose entirely.
  • Keep backtest results and live performance separate — a backtest cannot fully reproduce spread widening, slippage, gaps and disconnections, so neither can be inferred from the other.
  • The floating-loss limit applies while the EA is running and the market can be filled normally; across a gap or a break in liquidity the actual fills may differ from the level you set. The factory 90% is the widest option in the dropdown, and a triggered stop books a loss of close to ninety percent of the account.
