The strategy concept is based on capturing trend momentum through the rate of change of a custom moving average indicator (ima). Entry conditions: when no position is open and a new bar forms, the EA calculates the relative rate of change k1=(aIMA[0]-aIMA[1])/|aIMA[1]| from the ima indicator buffer; a buy signal triggers when k1>=k and a sell signal when k1<=-k. Exit conditions are twofold: a trailing stop mechanism that moves the stop loss to maintain a 'take' point distance from current price when the position is profitable and has moved beyond 'take' points, and a loss cutoff that forcefully closes the position when the calculated loss in ticks exceeds the 'drop' threshold. Position sizing dynamically calculates lot size as FreeMargin*r/drop/TickValue, rounds down to the nearest minimum lot step, then iteratively reduces until FreeMarginCheck passes, with additional caps at max_lots and SYMBOL_VOLUME_MAX. Money management uses the risk ratio parameter r to control exposure per trade, but has a critical flaw—positions are opened with zero stop loss price (sl=0 passed to PositionOpen), relying entirely on the OnTick loop to detect and close losing positions, which creates severe risk during disconnections or price gaps.
