Session range breakout EA: OCO stop orders around the early-session range, fixed risk per trade, break-even, ATR trailing stop and daily loss limit.
Many markets build a quiet range in the early hours and then break out once the main session opens. Trading that breakout by hand means waking up for it, placing two orders, cancelling the loser and managing the winner, every day.
This Expert Advisor measures the high and low of a set time window (server time, default 00:00 to 07:00) on the range timeframe. After the window closes it places a buy stop above the range and a sell stop below it, each a small ATR buffer away. When one side fills, the other order is cancelled; there is at most one trade per day. Days with a range that is too wide relative to ATR are skipped. Unfilled orders are removed at a set hour.
Risk and management:
- The stop loss sits on the other side of the range, capped at a multiple of ATR; the target is a set multiple of the stop.
- Lot size comes from a fixed percentage of the balance and the stop distance. If that lot is below the broker minimum, the minimum lot is used only when free margin covers it and it is within InpMaxLot; otherwise the order is skipped.
- The stop moves to entry plus one tick at a set multiple of the risk, then trails by ATR (only ever tightened).
- Everything is closed on Friday at a set hour. A daily loss limit closes all trades and pauses until the next day; an optional total drawdown floor stops the EA. Prop mode sets these to 4% daily and 8% total.
Before every order the EA takes a fresh price, keeps stop loss and take profit outside the broker stops level, freeze level and spread, rounds prices to the symbol tick size and checks volume limits and free margin for the exact order type. It never increases the lot after a loss and uses no grid, martingale or averaging. It does not use DLLs, web requests or external services, and it runs on any symbol and timeframe.
Recommended symbols and timeframes
- Range timeframe H1 (input InpTF); the chart timeframe does not matter.
- Liquid FX pairs such as EURUSD and GBPUSD, and XAUUSD. Adjust the range hours to your broker's server time zone.
