This project involves coding a fully automated scalping Expert Advisor for XAU-USD on the MT5 platform. Core trade logic • When price is rising, a sell-stop order must trail the move at a 100-point distance. (example 100 pt) • As soon as the pull-back triggers that pending order, a stop-loss immediately switches to trailing mode, following the retracement until price resumes upward and closes the position in profit. • The exact mirror applies in a falling market: a buy-stop order shadows the down-move, is filled on the bounce, and uses an identical trailing-SL routine. Deliverables 1. Compiled EA file (.ex5) plus full source code (.mq5). Acceptance criteria 2. The EA must place and trail pending orders exactly as described, and compile on the latest MetaEditor build without errors or warnings. Feel free to message for the full specification or to clarify the “Scalping EA” trend filter choice before coding begins.
