RSI Reversion EA
The entry is a rebound out of the extreme, not a touch of it: RSI crossing back above the oversold level (or back below the overbought level) is the first sign the extreme has stopped extending, which is a materially different - and more common - signal than entering the instant RSI first touches the level. The exit is signal-based rather than a fixed price target: the position closes the moment RSI recovers back through a configurable midline in its favour, because that midline crossing is what the trade was actually betting on. A fixed pip take profit chosen without reference to RSI would be an arbitrary number bolted onto a signal-driven idea. A hard pip stop still protects every position even though the intended exit is signal-based. RSI can sit pinned in oversold or overbought territory through a genuinely strong trend rather than reverting, and a reversion trade with no price-based backstop against that scenario is the standard way these systems blow up - the stop exists for that case, not the normal one. Notes and limitations - Mean reversion assumes the range holds. In a strong trend RSI can stay pinned at an extreme for long stretches without ever reverting to the midline, which is what the protective stop is for - it will be hit more often than the signal exit in trending conditions. - Signals are evaluated once per closed bar, not on every tick. - One position at a time, tracked by InpMagicNumber. It will not manage or interfere with trades opened manually or by another EA. - Requires AutoTrading enabled and IsTradeAllowed() true; if trading is disabled the EA logs it and skips the entry.
