为什么这个EA不能加仓？ 新评论 huaweibai 2018.04.18 11:04 EA思路，在MA10、MA20、MA30上方，每收盘一根阳线，发一张多单，收盘价小于MA10时，多单平仓；在MA10、MA20、MA30下方，每收盘一根阴线，发一张空单，收盘价大于MA10时，空单平仓。但是目前只有在EA加载后，第一个信号发出时开仓，而不能加仓。求各位大神帮忙查看一下，感激不尽。下面截图是EA源码：//+------------------------------------------------------------------+ //| Moving Average.mq4 | //| Copyright 2005-2014, MetaQuotes Software Corp. | //| http://www.mql4.com | //+------------------------------------------------------------------+ #property copyright "2005-2014, MetaQuotes Software Corp." #property link "http://www.mql4.com" #property description "Moving Average sample expert advisor" #define MAGICMA 20131111 //--- Inputs input double Lots =0.02;
