Mastering Resistance and Support Indicators in MetaTrader 5

Hey traders! Today, we’re diving into the essential world of resistance and support lines, specifically how they work with the iFractals indicator. It’s important to note that the last value of Fractals can change, which is why we analyze 5 additional bars for accuracy.

//--- number of values copied from the iFractals indicator 
   int values_to_copy=-1;
//--- if it is the first start of calculation of the indicator
   if(prev_calculated==0)
      values_to_copy=rates_total;
   else
     {
      //--- it means that it's not the first time of the indicator calculation, and since the last call of OnCalculate() 
      //--- for calculation not more than one bar is added 
      //--- value "+5" - because of the feature of drawing fractals
      values_to_copy=(rates_total-prev_calculated)+5;
     }

Now, if you want to compare the "Resistance & Support" and "Fractals" indicators in the strategy tester, here’s how to do it:

First, attach the "Fractals" indicator to a clear chart.
Next, right-click on the chart, go to Templates, and select Save Template. Name it "tester" to save the chart setup with the Fractals indicator in the "tester.tpl" template.
Then, you can start testing by:

Debugging on history (just hit "Ctrl" + "F5" in the MetaEditor)
Or doing some visual testing from the terminal in the Strategy Tester window.

Below, you’ll see how the "Resistance & Support" indicator performs in the strategy tester:
