多單必須採用ASK價格計算，空單必須採用BID價格計算，否則會有錯誤。
以及多單修改的止損位必須大於原本的止損位，空單修改的止損位必須小於原本的止損位。
试下这个
//修改已持仓订单或未成交的订单的止损或止盈，修改已持仓订单:orderType = 1; 修改已挂单但未成交的订单::orderType = 2; //例如：OrderModify(1,100, 50,magic); //修改已持仓订单止损100点 止盈50点 bool OrderModify(int orderType = 1, double stopLossPoints = 0, double takeProfitPoints = 0, uint MagicNumber = 0) { MqlTradeRequest request = {}; MqlTradeResult result = {}; double point = SymbolInfoDouble(_Symbol, SYMBOL_POINT); int direction = 0; double openPrice = 0; switch(orderType) { case 1: if (!PositionSelectByTicket(request.position)) { Print("Failed to select position by ticket"); return false; } direction = (PositionGetInteger(POSITION_TYPE) == POSITION_TYPE_BUY) ? 1 : -1; openPrice = PositionGetDouble(POSITION_PRICE_OPEN); request.volume = PositionsTotal(); break; case 2: if (!OrderSelect(request.order)) { Print("Failed to select order by ticket"); return false; } direction = (OrderGetInteger(ORDER_TYPE) == ORDER_TYPE_BUY) ? 1 : -1; openPrice = OrderGetDouble(ORDER_PRICE_OPEN); request.volume = OrdersTotal(); break; default: Print("Invalid order type"); return false; } ENUM_ORDER_TYPE_FILLING fillMode = (ENUM_ORDER_TYPE_FILLING) SymbolInfoInteger(_Symbol,SYMBOL_FILLING_MODE); fillMode -= 1; request.action = TRADE_ACTION_SLTP; request.symbol = _Symbol; request.magic = MagicNumber; request.type_filling = fillMode; request.sl = openPrice - direction * stopLossPoints * point; request.tp = openPrice + direction * takeProfitPoints * point; bool res = OrderSend(request, result); if (res) { Print("Order modified. Order:", request.position, " Lots:", request.volume); } else { Print("Failed to modify order. Error:", GetLastError()); } return res; }

我你的基础上稍微修改了一下，你试试吧，由于我没有你的使用环境，无法测试
void yidong(int tppoint_1, int tppoint_2, string symbol, ENUM_POSITION_TYPE type, int magic, string com) { // 遍历所有头寸 int totalPositions = PositionsTotal(); for (int i = totalPositions - 1; i >= 0; i--) { if (PositionGetTicket(i) > 0) { if (PositionGetString(POSITION_SYMBOL) == symbol) { // 获取当前市场报价 double bid = SymbolInfoDouble(symbol, SYMBOL_BID); double ask = SymbolInfoDouble(symbol, SYMBOL_ASK); long dig = SymbolInfoInteger(symbol, SYMBOL_DIGITS); double pot = SymbolInfoDouble(symbol, SYMBOL_POINT); // 选择当前头寸 PositionSelectByTicket(PositionGetTicket(i)); double op = PositionGetDouble(POSITION_PRICE_OPEN); double sl = PositionGetDouble(POSITION_SL); double tp = PositionGetDouble(POSITION_TP); // 止盈止损条件判断 if (type == POSITION_TYPE_BUY && magic == PositionGetInteger(POSITION_MAGIC) && com == PositionGetString(POSITION_COMMENT)) { if (ask - op >= pot * tppoint_1 && ask - op < pot * tppoint_2 && sl < op + tppoint_1 * pot) { MqlTradeRequest request = {}; MqlTradeResult result = {}; request.action = TRADE_ACTION_SLTP; request.position = PositionGetTicket(i); request.symbol = symbol; request.sl = op + tppoint_1 * pot; request.tp = op + tppoint_2 * pot; request.comment = com; request.magic = magic; // OrderSend 错误处理 if (!OrderSend(request, result)) PrintFormat("OrderSend error %d: %s", GetLastError()); } } if (type == POSITION_TYPE_SELL && magic == PositionGetInteger(POSITION_MAGIC) && com == PositionGetString(POSITION_COMMENT)) { if (op - bid >= pot * tppoint_1 && op - bid < tppoint_2 * pot && op - tppoint_1 * pot < sl) { MqlTradeRequest request = {}; MqlTradeResult result = {}; request.action = TRADE_ACTION_SLTP; request.position = PositionGetTicket(i); request.symbol = symbol; request.sl = op - tppoint_1 * pot; request.tp = op - tppoint_2 * pot; request.comment = com; request.magic = magic; // OrderSend 错误处理 if (!OrderSend(request, result)) PrintFormat("OrderSend error %d: %s", GetLastError()); } } // 在条件结束后取消选择头寸 PositionSelectByTicket(0); } } } }
