请教ChartSetSymbolPeriod切换货币对后,ma值都没变化
因为不想在每个货币对挂EA,就想在一个图表间隔切换货币对 ChartSetSymbolPeriod切换成功了,但是求出的移动平均值还是上一个货币对的均值 请问有没有人知道,问题大概出现在哪里? //+------------------------------------------------------------------+ //| myea.mq4 | //| Copyright 2016, metaQuotes Software Corp. | //| https://www.mql5.com | //+------------------------------------------------------------------+ #property copyright "Copyright 2016, metaQuotes Software Corp." #property link "https://www.mql5.com" #property version "1.00" #property strict //+------------------------------------------------------------------+ //| Expert initialization function | //+------------------------------------------------------------------+ int onInit() { //--- //--- return(INIT_SUCCEEDED); } //+------------------------------------------------------------------+ //| Expert deinitialization function | //+------------------------------------------------------------------+ void onDeinit(const int reason) { //--- } //+------------------------------------------------------------------+ //| Expert tick function | //+------------------------------------------------------------------+ double ma13 = iMA(NULL,0,13,0,MODE_SMA,PRICE_CLOSE,0); double ma5 = iMA(NULL,0,5,0,MODE_SMA,PRICE_CLOSE,0); string money[30] = {"EURUSD","USDJPY","EURJPY","AUDUSD","AUDJPY","CADJPY","CHFJPY","EURAUD","EURGBP","GBPJPY"}; void onTick() { if(Minute()%30 == 0){ checkMoney(0); }else if(Minute()%30 == 1){ checkMoney(1); }else if(Minute()%30 == 2){ checkMoney(2); }else if(Minute()%30 == 3){ checkMoney(3); }else if(Minute()%30 == 4){ checkMoney(4); }else if(Minute()%30 == 5){ checkMoney(5); }else if(Minute()%30 == 6){ checkMoney(6); }else if(Minute()%30 == 7){ checkMoney(7); }else if(Minute()%30 == 8){ checkMoney(8); }else if(Minute()%30 == 9){ checkMoney(9); } } //+------------------------------------------------------------------+ void checkMoney(int i){ if(Symbol() != money[i]){ if(ChartSetSymbolPeriod(0,money[i],0)){ }else{ alert(money[i]+"打开失败"); } } alert(ma5+","+ma13); } |
