Works based on two indicators: iCCI (Commodity Channel Index, CCI) and iMACD (Moving Average Convergence/Divergence, MACD). OnTradeTransaction().Â
As the CCI and MACD indicators have different scales of measurement, a conversion ratio has been introduced:
inputint      macd_coefficient=10000;      // alignment of cci and macd
The values are aligned here:
voidOnTick()
  { //—
  double cci=iCCIGet(back);
  double macd=iMACDGet(MAIN_LINE,back)*macd_coefficient;
  Comment(“cci: “,DoubleToString(cci,2),“\n”,
          “macd: “,DoubleToString(macd,Digits()+1),“\n”,
          “buyLevel: “,buyLevel);
The clear information on the obtained values is displayed here right away – for visual inspection.
Also, an interesting idea has been implemented — the EA (in the OnTradeTransaction() function) performs the summation of unprofitable and profitable trades (the “Number_of_losses” variable). If closed with a loss — “Number_of_losses” increases by “1”; if closed with profit, “Number_of_losses” decreases by “1”. When opening a position, the lot is calculated as: if “Number_of_losses“>”0” (this means that currently there are more positions closed with loss than with profit) increase the lot by the “increase” coefficient. If “Number_of_losses“<“0” (this means that currently there are more positions closed with profit than with loss) — the lot size is taken from the coefficient:
