Risk & Lot Settings
Lot sizing method
Lot Method determines how trade size is calculated for each new signal:
| Method | Risk Value means |
|---|---|
Risk Percent | Risk Value% of account balance per trade (default) |
Risk Amount | Risk a fixed dollar/currency amount per trade |
Fixed Size | Place every trade at exactly Value lots |
Example: Risk Percent + Risk Value = 1.0 — each trade risks 1% of your account. If your account is $10,000 and the SL is 30 pips, the EA calculates the correct lot size automatically.
Use Risk Percent with Risk Value = 0.5 or lower for prop-firm challenges to remain well within daily drawdown limits.
Scale-in (Multi-Trade Mode)
Scale-In Mode controls whether the EA opens additional trades in the same direction while one is already open:
| Mode | Behaviour |
|---|---|
Disabled | Only one trade per direction at a time (default) |
On New Signal | Opens an additional trade when a new valid signal fires |
On Breakeven | Opens an additional trade once the first reaches break even |
Maximum Open Trades caps the total number of simultaneously open trades regardless of scale-in mode. Default is 3.
Max signals per session
Max Signals Per Session (default 0 = disabled) limits how many new trades the EA can initiate within a single session window. The counter resets when the next session opens.
Margin handling
Strict Margin Rejection (default false) — when enabled, a trade is completely rejected if the calculated lot size would exceed available margin. When disabled, the lot size is reduced to fit within margin. Enabling this gives more realistic backtest behaviour matching live account constraints.
Magic number
Magic (default 40001) is the unique identifier stamped on every order the EA places. The EA uses this to identify and manage only its own trades.
Use Magic Number Filter (default true) — when true, the EA only manages trades with its own magic number. When false, it manages all trades on the symbol (advanced use only — use with caution on a shared account).
