Labouchere System EA is an automated trading tool for MetaTrader 4. It opens trades on several currency pairs, closes each one at a fixed take profit or stop loss, and changes its lot size using the Labouchere system, a staged betting progression, instead of a plain martingale.
Every trade uses a take profit and a stop loss set at the same distance in pips. This makes each result roughly one unit of gain or one unit of loss, which suits a progression system. After each closed trade the EA looks at the recent sequence of wins and losses and adjusts the next lot size according to the Labouchere rules. A win moves the sequence one way and a loss moves it the other. The aim is to let lot size change gradually, rather than doubling after every loss as a martingale does.
The EA is meant to run across many charts and several currency pairs at once. Each chart uses one of six entry logics, so losses on one pair or logic are less likely to line up with losses on another. The lot size is based on the combined outcomes of all charts, not on each chart alone.
The EA is built for multiple currency pairs. The exact list of pairs, the timeframe for each chart and the number of charts are set out in the manual, so confirm them before you attach the EA anywhere. Brokers use different symbol names and suffixes, so you may need to match the names in your Market Watch.
Parameter names and defaults are not listed here. Check the manual and the inputs window after you attach the EA. These are the types of input you should look for and understand:
| Input type | What to check |
|---|---|
| Base lot size | The starting unit used by the progression |
| Maximum lot or step limit | Whether lot growth is capped and where |
| Take profit and stop loss | The fixed pip distance and how it suits your broker's spread |
| Magic number | Used to tell trades on different charts apart |
| Trading hours or filters | Any session or spread limits that are offered |
Any progression system raises position size at some stage, and a long losing run can cause a large drawdown. Fixed pip targets are also affected by spread, slippage and requotes. Run the EA on a demo account first, compare its forward results with the public signal record, and use a lot size and deposit you are comfortable with.
Trading carries risk, and you can lose some or all of your capital. Past results, including backtests and signal records, do not predict future ones.
A VPS is a sensible choice for an EA that runs on many charts, because it keeps the terminal connected without interruption.

No. This is an MT4 expert advisor and will not load in MetaTrader 5. If you use MT5, look for a product built for that platform instead.
Copy the file into the MQL4/Experts folder through File > Open Data Folder in MT4, then restart the terminal or refresh the Navigator. Drag the EA onto a chart and make sure AutoTrading is switched on and live trading is allowed in the EA properties.
The design spreads trades across many charts and several currency pairs, each with its own entry logic. Check the manual for the recommended pairs, timeframes and number of charts before you start, and test on a demo account first.
Any MT4 broker may work, but fixed take profit and stop loss distances are sensitive to spreads, slippage and execution speed. Check the manual for recommended conditions and run it on a demo account with your broker first.
The exact parameters and a suitable minimum balance are not stated here, so read the manual supplied with the product. Because lot size can rise after losses, choose a deposit and a base lot that you could tolerate losing, and check how the maximum lot is limited.
Treat them with caution. Lot sizes depend on the results of trades across all charts together, so a single-chart backtest cannot reproduce live behaviour. Forward testing on a demo account is a more useful check. Trading carries risk and past results do not predict future ones.
