1. 输入参数
#define ExtBotName "AK-47 Scalper EA" //机器人名称 #define Version "1.00" //--- 输入参数 --- extern string EASettings = "---------------------------------------------"; //-------- <EA 设置> -------- input int InpMagicNumber = 124656; //魔术数字 extern string TradingSettings = "---------------------------------------------"; //-------- <交易设置> -------- input double Inpuser_lot = 0.01; //手数 input double InpSL_Pips = 3.5 //止损（点数） input double InpMax_spread = 0.5 //允许的最大点差（点数）（0 = 浮动） extern string MoneySettings = "---------------------------------------------"; //-------- <资金设置> -------- input bool isVolume_Percent = true; //允许按比例计算手数 input double InpRisk = 3 //风险百分比（%） input string TimeSettings = "---------------------------------------------"; //-------- <交易时间设置> -------- input bool InpTimeFilter = true //交易时间过滤 input int InpStartHour = 2 //开始小时 input int InpStartMinute = 30 //开始分钟 input int InpEndHour = 21 //结束小时 input int InpEndMinute = 0 //结束分钟
2. 本地变量初始化
//--- 变量 --- int Pips2Points; // 滑点 3点 3=点数 30=点数 double Pips2Double; // 止损 15点 0.015 0.0150 int InpMax_slippage = 3; // 允许的最大滑点 bool isOrder = false; // 仅打开1个订单 int slippage; string strComment = "";
3. 主代码
a/ 专家初始化函数
int OnInit() { //--- //3或5位数字检测 //点与点数 if (Digits % 2 == 1) { Pips2Double = _Point*10; Pips2Points = 10; slippage = 10* InpMax_slippage; } else { Pips2Double = _Point; Pips2Points = 1; slippage = InpMax_slippage; } //--- return(INIT_SUCCEEDED); }
b/ 专家滴答函数
void OnTick() { //--- if(IsTradeAllowed() == false) { Comment("AK-47 EA\n交易不允许."); return; } MqlDateTime structTime; TimeCurrent(structTime); structTime.sec = 0; //设置开始时间 structTime.hour = InpStartHour; structTime.min = InpStartMinute; datetime timeStart = StructToTime(structTime); //设置结束时间 structTime.hour = InpEndHour; structTime.min = InpEndMinute; datetime timeEnd = StructToTime(structTime); double acSpread = MarketInfo(Symbol(), MODE_SPREAD); StopLevel = MarketInfo(Symbol(), MODE_STOPLEVEL); strComment = "\n" + ExtBotName + " - v." + (string)Version; strComment += "\nGMT时间 = " + TimeToString(TimeGMT(),TIME_DATE|TIME_SECONDS); strComment += "\n交易时间 = [" + (string)InpStartHour + "h" + (string)InpStartMinute + " --> " + (string)InpEndHour + "h" + (string)InpEndMinute + "]"; strComment += "\n当前点差 = " + (string)acSpread + " 点数"; strComment += "\n当前止损水平 = " + (string)StopLevel + " 点数"; Comment(strComment); //更新值 UpdateOrders(); TrailingStop(); //检查交易时间 if(InpTimeFilter) { if(TimeCurrent() >= timeStart && TimeCurrent() < timeEnd) { if(!isOrder) OpenOrder(); } } else { if(!isOrder) OpenOrder(); } }
3.1 计算信号以发送订单
void OpenOrder(){ //int OrdType = OP_SELL;//-1; double TP = 0; double SL = 0; string comment = ExtBotName; //计算手数 double lot1 = CalculateVolume(); //if(OrdType == OP_SELL){ double OpenPrice = NormalizeDouble(Bid - (StopLevel * _Point) - (InpSL_Pips/2) * Pips2Double, Digits); SL = NormalizeDouble(Ask + StopLevel * _Point + InpSL_Pips/2 * Pips2Double, Digits); if(CheckSpreadAllow()) //检查点差 { if(!OrderSend(_Symbol, OP_SELLSTOP, lot1, OpenPrice, slippage, SL, TP, comment, InpMagicNumber, 0, clrRed)) Print(__FUNCTION__,"--> 发送订单错误 ",GetLastError()); } //} }
3.2 计算手数
double CalculateVolume() { double LotSize = 0; if(isVolume_Percent == false) { LotSize = Inpuser_lot; } else { LotSize = (InpRisk) * AccountFreeMargin(); LotSize = LotSize /100000; double n = MathFloor(LotSize/Inpuser_lot); //Comment((string)n); LotSize = n * Inpuser_lot; if(LotSize < Inpuser_lot) LotSize = Inpuser_lot; if(LotSize > MarketInfo(Symbol(),MODE_MAXLOT)) LotSize = MarketInfo(Symbol(),MODE_MAXLOT); if(LotSize < MarketInfo(Symbol(),MODE_MINLOT)) LotSize = MarketInfo(Symbol(),MODE_MINLOT); } return(LotSize); }
3.3 EA具有“跟踪止损”功能， 止损会在每次价格变动时改变（下跌）
void TrailingStop() { for(int i = OrdersTotal() - 1; i >= 0; i--) { if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) { if((OrderMagicNumber() == InpMagicNumber) && (OrderSymbol() == Symbol())) //_Symbol)) { //对于卖出订单 if(OrderType() == OP_SELL) { //--当价格变化时计算止损 double SL_in_Pip = NormalizeDouble(OrderStopLoss() - (StopLevel * _Point) - Ask, Digits) / Pips2Double; if(SL_in_Pip > InpSL_Pips){ double newSL = NormalizeDouble(Ask + (StopLevel * _Point) + InpSL_Pips * Pips2Double, Digits); if(!OrderModify(OrderTicket(), OrderOpenPrice(), newSL, OrderTakeProfit(), 0, clrRed)) { Print(__FUNCTION__,"--> 修改订单错误 ",GetLastError()); continue } } } //对于卖出止损订单 else if(OrderType() == OP_SELLSTOP) { double SL_in_Pip = NormalizeDouble(OrderStopLoss() - (StopLevel * _Point) - Ask, Digits) / Pips2Double; if(SL_in_Pip < InpSL_Pips/2){ double newOP = NormalizeDouble(Bid - (StopLevel * _Point) - (InpSL_Pips/2) * Pips2Double, Digits); double newSL = NormalizeDouble(Ask + (StopLevel * _Point) + (InpSL_Pips/2) * Pips2Double, Digits); if(!OrderModify(OrderTicket(), newOP, newSL, OrderTakeProfit(), 0, clrRed)) { Print(__FUNCTION__,"--> 修改挂单错误!", GetLastError()); continue } } } } } }
