帮什么忙？

Freeman5383

小弟想为这个 indicator 加入 MA 原来的所有功能，可是写来写去就是不通~~~（唉~可能我真的没这方面的学习能力吧~~）

所以才不好意思麻烦大大们帮帮忙~~~

这个 indicator 有三条 MA ， 基本功能如 ：Period , Mode , Shift 已经有了 ，唯独 Apply to （ Open / Close / High / Low / HL/2 / HLC/3 / HLCC/4 ）这个功能没写进去~~

所以小弟想请大大帮忙为每条 MA 都加入这功能 ~~

感激不尽~~~

double iMA( string symbol, int timeframe, int period, int ma_shift, int ma_method, int applied_price, int shift)

要加在哪里？？？？？

manual一点的方法。
fasterMAnow      = iMA(NULL, 0, FasterMA, FasterShift, FasterMode,  PRICE_CLOSE, i+1);
      fasterMAprevious = iMA(NULL, 0, FasterMA, FasterShift, FasterMode,  PRICE_CLOSE, i+2);
      fasterMAafter    = iMA(NULL, 0, FasterMA, FasterShift, FasterMode,  PRICE_CLOSE, i-1);
      
      mediumMAnow      = iMA(NULL, 0, MediumMA, MediumShift, MediumMode,  PRICE_CLOSE, i+1);
      mediumMAprevious = iMA(NULL, 0, MediumMA, MediumShift, MediumMode,  PRICE_CLOSE, i+2);
      mediumMAafter    = iMA(NULL, 0, MediumMA, MediumShift, MediumMode,  PRICE_CLOSE, i-1);
      
      slowerMAnow      = iMA(NULL, 0, SlowerMA, SlowerShift, SlowerMode,  PRICE_CLOSE, i+1);
      slowerMAprevious = iMA(NULL, 0, SlowerMA, SlowerShift, SlowerMode,  PRICE_CLOSE, i+2);
      slowerMAafter    = iMA(NULL, 0, SlowerMA, SlowerShift, SlowerMode,  PRICE_CLOSE, i-1);


把PRICE_CLOSE 换PRICE_TYPICAL，PRICE_OPEN。 之后compile.
   请看这里http://docs.mql4.com/constants/prices

auto一点的方法。
在 extern int SoundAlert =    1; // 0 = disabled 下面加这个line。


extern int MyMAType =    0; // 0=Price_close, 1=Price_open


之后把以上的 PRICE_CLOSE 换成   MyMAType 。
之后compile.
