Here is the bulk of your code repair. However it does not address all the nuances of multiple tops/bottoms as can be seen here:

Code snippet:


/***********************************************************************/
bool IsFractalBuySignal(SCFloatArrayRef InDataLow, SCFloatArrayRef InDataHigh, int index, int ArraySize)
{
  if (  
    ( ((index+2) <= (ArraySize-1)) &&
    InDataHigh[index] > InDataHigh[index + 1] && InDataHigh[index] > InDataHigh[index + 2] &&
    InDataHigh[index] > InDataHigh[index - 1] && InDataHigh[index] > InDataHigh[index - 2]
  )
    ||
    ( ((index+3) <= (ArraySize-1)) &&
    InDataHigh[index] > InDataHigh[index + 2] && InDataHigh[index] > InDataHigh[index + 3] &&
    InDataHigh[index] > InDataHigh[index - 1] && InDataHigh[index] > InDataHigh[index - 2] &&
    InDataHigh[index] == InDataHigh[index + 1]
  )
    ||
    ( ((index+4) <= (ArraySize-1)) &&
    InDataHigh[index] > InDataHigh[index + 3] && InDataHigh[index] > InDataHigh[index + 4] &&
    InDataHigh[index] > InDataHigh[index - 1] && InDataHigh[index] > InDataHigh[index - 2] &&
    InDataHigh[index] == InDataHigh[index + 1] && InDataHigh[index + 1] == InDataHigh[index + 2]
  )
    )
    return true;

  return false;
}

  return false;
