Overview
MeanRevert EA trades the statistical tendency of price to return toward its Daily SMA after extended deviations. When the D1 close moves more than a configured percentage away from the SMA, the EA opens a position in the reversion direction and exits when price approaches the mean again — capturing the snapback move.
The EA supports 9 instruments with fully optimised, hardcoded parameter sets per symbol and risk level. No manual configuration required — attach, select your preset, and the EA is ready to trade.
Supported Symbols
US30 · US500 · USTEC · EURUSD · GBPUSD · GBPJPY · EURJPY · USDJPY · AUDCAD
How It Works
At each new Daily bar close, MeanRevert measures the deviation between the closing price and the Daily SMA. If deviation exceeds the entry threshold for the detected symbol, a pending signal is stored. After a 1h10m guard period (avoiding the illiquid market open), the order is executed at market. The position is held until price returns within the exit threshold of the SMA, at which point it closes with a market order on the next tick.
An optional scale-in allows a second position to be added if price deviates further by a configurable multiplier — averaging into the trade at a more extreme level.
