我是新手,第一个EA就翻了五倍.... 中彩了!请高手解答!
其实就是MT4自带的MA系统,修改了下参数....测试结果翻了五倍,虽然仍会爆仓,不过志在学习了!现有几个问题: 1,这个系统的资金管理是什么原理?为什么我设仓位是一手,会出现2.2手斟至14.9手............. 2,我测试的时间是90至今,却只成交了四单......... 3,如果有达人把系统的英文提示翻译或解说一下就万分感谢了,好多地方我都不明白,只是依胡画瓜,但是我想从零开始认真学习! 侠版的教学不错,但是偶没有分.........5555555555555~ //+------------------------------------------------------------------+ //| Moving Average.mq4 | //| Copyright ?2005, metaQuotes Software Corp. | //| http://www.metaquotes.net/ | //+------------------------------------------------------------------+ #define MAGICMA 20050610 extern double Lots = 1; extern double MaximumRisk = 0.2; extern double DecreaseFactor = 1; extern double MovingPeriod = 200; extern double MovingShift = 10; //+------------------------------------------------------------------+ //| Calculate open positions | //+------------------------------------------------------------------+ int CalculateCurrentOrders(string symbol) { int buys=0,sells=0; //---- for(int i=0;i0) return(buys); else return(-sells); } //+------------------------------------------------------------------+ //| Calculate optimal lot size | //+------------------------------------------------------------------+ double LotsOptimized() { double lot=Lots; int orders=HistoryTotal(); // history orders total int losses=0; // number of losses orders without a break //---- select lot size lot=NormalizeDouble(AccountFreeMargin()*MaximumRisk/1000.0,1); //---- calcuulate number of losses orders without a break if(DecreaseFactor>0) { for(int i=orders-1;i>=0;i--) { if(OrderSelect(i,SELECT_BY_POS,MODE_HISTORY)==false) { Print("Error in history!"); break; } if(OrderSymbol()!=Symbol() || OrderType()>OP_SELL) continue; //---- if(OrderProfit()>0) break; if(OrderProfit()1) lot=NormalizeDouble(lot-lot*losses/DecreaseFactor,1); } //---- return lot size if(lot1) return; //---- get Moving Average ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0); //---- sell conditions if(Open[1]>ma && Close[1]1) return; //---- get Moving Average ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0); //---- for(int i=0;ima && Close[1] |
