帮忙修改下EA
|
从网上找到个EA，名叫“GridMonster".我自己改了一下，加了个trailStart功能。还想加几个功能： 1、extern double trailstep=0 //跟踪止损步进点数，以免在5位数平台频繁修改止损，0为停用此功能。 2、extern int shortpositionmaxlose=0 //当亏损卖单超过多少个时，停止开卖单，0为停用此功能。 3、extern int longpositionmaxlose=0 //当亏损买单超过多少个时，停止开买单，0为停用此功能。 刚接触mql4语言，许多功能不知道怎么实现，请高手赐教。 以下是源码： extern int uniqueGridMagic = 550000;
