搞MT4一年了，发个我在使用的EA，改写了一下，没有策略部的，当然，有些代码是在网上“山寨”过来的，改成这样的工具，如默认的止损，止盈，时间止损等，移动止损，帐户余额保护等等，作为辅助交易的工具,可以在手工交易时就非常非常有用了 这个EA代码已经实战了很长时间，能够正常使用的，只是策略部分自己的思路还不够好。自己也一直在完善细节的部分，也一直有测试自己的策略，挂机测试，希望与各位共同学习提高。 以下是基本的功能介绍： 1）4位报价，5位报价都适用。所说的点，都是按第4位小数的值，在5位报价平台也是如此。 2）帐户余保护，可以设置最大亏损百分比后就关仓。 3）开仓单最大亏损百分比关仓。 4）BEP，即设置到达一定的利润点后，就保护多少点值。 5）移动止损。 6）利润保护，可设置不同的利润保护等级，最多5个等级 7）日期及时间的设置，指定日期及时间段开平仓。本来有EA中使用的，但现在将策略部分删除了，意义不大 8）时间止损，可以设定一定时间内，单子不盈利就关掉 Code: #include <stdlib.mqh> #include <stderror.mqh> #include <WinUser32.mqh> extern bool Debug = false; extern string UserComment = ""; extern int MagicNum = 0; extern bool EADisabled = false; extern bool EmergencyCloseAll = false; extern int Portion = 1; extern bool UseAccountProtect = false; extern double StopTradePercent = 50; // percent of account balance lost before trading stops extern double MaxDDPercent = 60; // Percent of portion for max drawdown level. extern bool MoveToBEP = true; extern int MoveStopWhenPoint = 48; extern int LockProfit = 3; extern string mm8 = "OrderProfitProtect Settings"; extern bool UseOrderProfitProtect = true; extern int BeginProtectPositions = 2; extern double ProfitProtectLevel_0_Pips = 50; extern double ProfitProtectLevel_0_Percen = 10; extern double ProfitProtectLevel_1_Pips = 120; extern double ProfitProtectLevel_1_Percen = 20; extern double ProfitProtectLevel_2_Pips = 220; extern double ProfitProtectLevel_2_Percen = 40; extern double ProfitProtectLevel_3_Pips = 280; extern double ProfitProtectLevel_3_Percen = 50; extern double ProfitProtectLevel_4_Pips = 380; extern double ProfitProtectLevel_4_Percen = 60; extern double ProfitProtectLevel_5_Pips = 450; extern double ProfitProtectLevel_5_Percen = 70; //----------------------------------------------------- extern string s08 = "--TRADING TIME MANAGEMENT--"; extern string TTM1 = "Set time frames when new trades can open."; extern string TTM2 = "If Starthour = Stophour, then trade 24/5."; extern string TTM3 = "If TTMGoFlat=true, close all open trades"; extern string TTM4 = "when outside trading hours or days."; extern bool EnableTradeTimeManage = false; extern int ManualGMToffset = 3; // Set your broker's GMT Offset extern int GMTStartHour = 0; // Start trading at 0:00/GMT extern int GMTStopHour = 0; // Stop trading at 23:59/GMT extern bool TradeOnFriday = true; extern int FridayGMTStopHour = -1; // If set to 0 or higher, will prevent new trades from opening on Friday starting at that hour GMT. extern bool TTMGoFlat = false; extern string s12 = "-- Use this section to exclude trading days"; extern bool EnableBlackout = false; extern int StartBlackoutDay = 20; extern int StartBlackoutMonth = 12; extern int StopBlackoutDay = 15; extern int StopBlackoutMonth = 01; int StartBlackout = 0; int StopBlackout = 0; //----------------------------------------------------- extern bool UsingTakeProfit = true; extern int TakeProfit = 300; extern bool UsingStopLoss = true; extern double StopLoss = 39; // piont extern bool UsingTrailingStop = false; extern double TrailingStop = 55;//piont extern bool UsingHiLoTrailingStop = true; extern bool UsingTimeStopLoss = true; extern int TimeStopLossMin = 125; //Minute string myType = "ALL"; int Magic; string Type; double myPoint; datetime BarTime; double Lot; double StopTradeBalance; double InitialAB; double MaxDDPer; double MaxDD; double OrdersBuyLots; double OrdersSellLots; double MaxTradeLots; int OrderCount; int BuyOrderCount; int SellOrderCount; double OrderProfitPips = 0; double OrderProfits = 0; double MaxOrderProfitPips = 0; double LastOrderOpenPrice; //---signal variable int BaseEntrySignal; int AddPositionSignal; int CloseSignal; int SignalFilter; double uplevel; double dnlevel; // Comment variable string txt; //+------------------------------------------------------------------+ //| expert initialization function | //+------------------------------------------------------------------+ int init() { //---- myPoint = SetmyPoint(); Magic = 0; Type = "ALL"; while (!IsConnected()) { Comment("Waiting for connection..."); Sleep(10000); } StartBlackout = DayNumber(StartBlackoutMonth, StartBlackoutDay); StopBlackout = DayNumber(StopBlackoutMonth, StopBlackoutDay); InitialAB=AccountBalance(); StopTradeBalance=InitialAB - InitialAB*(StopTradePercent/100); //---- return(0); } //+------------------------------------------------------------------+ //| expert deinitialization function | //+------------------------------------------------------------------+ int deinit() { //---- //---- return(0); } //+------------------------------------------------------------------+ //| expert start function | //+------------------------------------------------------------------+ int start() { if (EADisabled == true) { if (IsTesting()) Comment("EA Disabled!

日系货币也能适用，2位3位报价均可，还有是紧急情况下关闭多个仓位的，都是较方便的。 另外， 如果是作为手工辅助交易工具的，还需要在 ModifyDefaultStopLoss函数中 for(int i = 0;i<total;i++) { if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES) ==false) continue; if(!isOrder(OrderSymbol(), OrderMagicNumber(), OrderComment(), myType)) continue; 的下方，加入 if(!(OrderStopLoss() == 0 || OrderTakeProfit() == 0)) continue; 本来，这个EA不是作为辅助工具而开发的，所以考虑不太周全，如果朋友能用上，或者可以提点意见去完善一下
很强！ 7）日期及时间的设置，指定日期及时间段开平仓。本来有EA中使用的，但现在将策略部分删除了，意义不大——指定日期及时间段开、平仓，这个意义还是很大的，另外指定时间全撤单也有意义。 另外大部分MT4的经纪公司都限制单笔委托的最大手数的，所以常常需要将计算得到的总委托手数分解成多笔委托（每笔委托手数限制在经纪公司允许的最大手数内或自定义的手数内）。
