XAU Layer Engine

• It trades gold automatically when the conditions of one of its 16 modules are met. The panel names the modules A01-A08 (group A) and B01-B08 (group B). Each module trades one side only, buy or sell.
• Only one basket is open at a time. While a basket is open, no other module starts one.
• A basket starts with one position. If price moves against it, the EA can add positions in the same direction, up to 5 in total. Every position uses the same lot. The lot does not grow from one position to the next (no martingale).
• Every basket has a stop loss. Most baskets close with a small profit. A basket that keeps going the wrong way closes at its stop loss with all its positions.
• If the free margin is too small to add the next position, the basket adds no more positions and its stop loss still applies.
• It rests on some days (see "Days with no new baskets").

1. MetaTrader 5 on Windows (a PC or a Windows VPS) and a hedging account. A netting account is refused: the EA stops at start with the message "a basket needs separate positions: use a hedging account" in the Experts tab.
2. A chart of your broker's gold symbol: XAUUSD, or the same with a suffix such as XAUUSDm. Any timeframe. On a symbol that is not gold the EA does not start.
3. A terminal that runs 24/5: a VPS, or a computer that is always on and online. The EA holds each basket's stop itself, so a terminal that is off cannot close a basket.
4. WebRequest allowed for the licence check: Tools > Options > Expert Advisors > tick "Allow WebRequest for listed URL" and add all three:
   • https://zab-license.bangzeed.workers.dev
   • https://zab-license.vercel.app
   • https://license.forexreviewth.com
5. A licence for your account number: send the account number to support (https://m.me/forexreviewth). A demo account needs no licence. On a real account the first start gives a 3-day trial; the dashboard then shows TRIAL with its end date. Without a licence the EA opens no new basket. A basket that is already open is still managed to its end.
6. Enough free margin for 5 positions at your lot. Another EA on the same account uses margin too.

1. In MT5 open File > Open Data Folder, copy XAULayerEngine.ex5 into MQL5\Experts\, then right-click Experts in the Navigator > Refresh.
2. Open a chart of your gold symbol and drag XAU Layer Engine onto it.
3. In the Common tab tick "Allow Algo Trading". In the Inputs tab set the inputs (keep the defaults at first). Press OK.
4. Turn on the Algo Trading button in the toolbar. The dashboard appears on the chart, and the Experts tab shows a start line with the version, the server clock and the risk mode.
5. Run one copy per account. A second copy on another chart needs its own Magic number (see Inputs) and doubles the margin in use and the risk.

Risk modes (Low / Mid / High)

The lot grows with your balance: 0.01 lot for every full amount of balance shown below. The % columns are for a balance of exactly one, two, three ... times that amount, which is the worst point. A balance in between risks less.

Example, Low mode: balance 6,000 USD → 0.01 lot per position; 11,999 USD → still 0.01; 12,000 USD → 0.02.

Fixed lot

Every position uses the lot you set, whatever the balance. When the balance falls, the lot does not, so the risk in % grows during a losing run.

• The lot is rounded down to a size your broker accepts and kept within the broker's smallest and largest lot. The Experts tab says so when it changes your value.
• If the balance at start is under the right-hand column, the Experts tab shows a WARNING line. The EA still trades.
• STATS > "Balance per 0.01 lot" shows how much balance you hold now for each 0.01 lot. Compare it with the risk mode table.
• On cent and non-USD accounts the Fixed lot is used as typed. The money per lot is then different from this table.

Cent accounts and other account currencies

The risk modes convert for you. The guard "0.01 lot = ..." (MODULES tab) shows what 0.01 lot earns for each 1.00 move of the gold price, in your account money. The EA multiplies the amounts of the risk mode table by it, and the panel footer shows the result, for example "0.01 lot per 6,000 USC".

• On a normal cent account the learning floor of 5,000-10,000 USC gets 0.01 lot in Low mode. At 5,000 USC that is a little more risk than the Low row: a typical full-basket loss is about 2.4 % of the balance and the worst about 4.2 %.
• Test a cent or non-USD account on a demo of the same account type first, and check that the guard shows the value in this table.
• If the Experts tab ever shows a line with "do not trust lots", do not trade on that account. Contact support.

The EA does not start a new basket:

• on some scheduled major US news days,
• before the weekend close on Friday,
• in some market conditions,
• on your own extra pause dates (see Inputs).

A basket that is already open is still managed on these days. The panel then shows PAUSED (or HOLD) with a short reason.

The news days are built in through 2027. On a live chart the EA also reads MetaTrader's economic calendar, so a news day that moves is followed. If the Experts tab says the news calendar is not available, the EA uses its built-in dates. Ask support once a year for the newest build, so the built-in days stay up to date.

The EA was built and tested on the server clock most MT5 brokers use: GMT+2 in winter, GMT+3 in summer. The EA reads your server's clock by itself and shows it as the guard "Clock NY +7" (MODULES tab; +7 = that common broker clock) and in the footer (server time and New York time).

On a server with another clock the EA converts by itself. The guard then shows another number in amber: that is information, not an error. On a test server with another clock about 84 % of the entries came at the same minute as on the reference server; the rest differ because each broker's prices differ. Profit always differs with each broker's spread, commission and swap.

If your broker's gold has no daily trading break, or the guard shows a number that looks wrong, test on demo first and ask support. The input "Server hours ahead of New York when it cannot be read" is used only when the EA cannot read the clock.

Figures cover this run: from the moment the EA was first attached with this Magic number on this symbol in this terminal. They survive a restart and a change of inputs. They count closed baskets after swap and commission, dated by server time, and a basket counts once, when its last position closes. The input "Start the dashboard history from now" starts a new run.

Click the header to fold or open the panel. A- / A+ change the size. The panel remembers its tab, size, fold and curve range for each chart. Turning the panel off does not change trading.

Header

From left to right: logo and name; the line "symbol · 16 modules · risk mode · version"; the licence card; A- / A+; the status.

Licence card (centre)

Status (top right)

Left column (on every tab)

• THIS MONTH: result of the month, % of the balance at the month start, a bar with the days in profit, and the number of baskets.
• BALANCE: curve of the closed balance. WEEK / MONTH / ALL choose the range. Bottom left: the start date of the range; bottom right: the change over the range.
• TODAY: today's result and baskets. OPEN RESULT: the floating result of the open basket and how many positions are open. SINCE START: return of the run in %. DRAWDOWN: the fall from the highest closed balance, now and the largest of the run.
• BASKET NOW:
  • A basket is open: the module (for example B04), BUY or SELL with the lot per position, the open result, how long it has been open, one dot for each position ("3 / 5 layers") and the price of the last position. If the next position cannot be added for margin, the line says "no margin for the next layer" in red. "closing, market closed: retrying" means the EA closes the basket as soon as the market opens.
  • No basket: "waiting for a signal" (blue), "paused: reason" (amber), "no licence, no new basket" (red), or another short state. Top right: how many modules are working at this moment ("6 of 16 modules active"). Below: the lot of the next basket.
  • "N positions, no module comment" (red): positions with this EA's Magic number that it cannot manage. Close them by hand.

Tabs (right card)

• MONTH: calendar of the month, Monday to Friday. Each day shows its result and baskets, green for profit, red for loss; today has a gold ring. The WEEK column holds week totals. The line on top shows the month result, days in profit, best day and worst day. The arrows go back to earlier months of the run; LATEST returns to this month.
• YEAR: the 12 months of the year. Each box shows the result, the % of the closed balance at the month start, the baskets and the days up. The line on top shows the year result and %, months in profit, best and worst month. The arrows go to earlier years; a click on a month opens its calendar.
• MODULES: the 16 modules with ID, SIDE (buy or sell), NOW, TODAY, MONTH, BASKETS, WIN%, LOSS (losing baskets) and LAST 20 (one bar per basket, green win, red loss, newest on the right). The module of the open basket is highlighted. NOW shows:

• GUARDS (bottom of the MODULES tab):

• STATS: "This run" since the start date, with trading days and baskets. PROFIT FACTOR (gross profit / gross loss), WIN RATE (with the losing baskets), RETURN (% on the run start balance), DRAWDOWN (largest on closed results, and now). The balance curve of the run marks the largest drawdown. BEST / WORST: best day, worst day, losing days in a row, biggest losing basket, green days. RUN + MONEY: run started, closed P/L, risk mode, lot of the next basket, balance per 0.01 lot.

Footer

Balance, equity, spread now / recent average, ping, server time · New York time. Right: "0.01 lot per ..." is the balance for each 0.01 lot of your risk mode, in your account money (in Fixed lot mode: the balance you hold now for each 0.01 lot).

Restart. You can close the terminal, restart the VPS or change inputs at any time. On start the EA finds its open positions by the Magic number and its own position comments and goes on managing the basket, without opening it twice.

• Do not change the Magic number while a basket is open.
• Do not close, add or change the EA's positions by hand. If you decide to close a basket by hand, close all of its positions together.
• If the panel shows CHECK POSITIONS, close the positions it found by hand; then the EA starts again.

VPS move

1. Move when no basket is open (status RUNNING or PAUSED), if you can.
2. Remove the EA from the old terminal (or turn off Algo Trading there) before you start it on the new one, so two terminals never manage the same basket.
3. Install on the new terminal with the same inputs and the same Magic number. An open basket is picked up. The dashboard history starts again on the new terminal.

Updates

1. Get new builds from support only. Ask once a year, so the built-in news days stay up to date.
2. Update when no basket is open, if you can. Copy the new XAULayerEngine.ex5 over the old one in MQL5\Experts\. MT5 reloads it on the chart; if not, remove the EA from the chart and attach it again.
3. Check that the header shows the new version and that the inputs are still yours. With the same Magic number on the same terminal the dashboard history goes on.

Before you trade real money, check

• 2-4 weeks on a demo of the same account type (cent, standard, your account currency).
• The licence card shows LICENSED, and the guard "0.01 lot = ..." shows the value for your account type.
• You worked out your own worst case: for each 0.01 lot per position, 211 for one basket and 361 for a losing run (USD, or USC on a cent account), and you can accept losing that. Live losses can be bigger.
• The terminal runs on a VPS or an always-on computer.
