coding candle retracements

[Adam Woods]

Hello fellow coders,

I am looking for ways to code price action within a candle. for instance writing code for when a candle has retraced more than 50% from its high. A point in the right direction would be much appreciated. Thank you

Adam Woods: has retraced more than 50% from its high.

2. Learn to code.

   double h   = High[0], o = Open[0],
          ret = (h + o) / 2; // Or general: ret = o + (h - o) * percent/100 
   if(Bid < ret) retraced();

   I suggest you add an additional filter such as the high must be at least ½ × ATR since one tick up and one tick down is 100% retrace from the high.
