NinjaTrader and all other platforms are sensitive to complex/heavy calculations, so, like our previous debugger tool this one is also useful to measure execution timing for methods (OnBarUpdate, OnRender, OnMarketData) in live on charts.

You should just rename the indicator_base name MY_indicator to your indicator base. Then in the start and end of overload methods, use:

protected void OnBarUpdate()
{
   debugTimer(true);
   ...
   ...
   your codes here
   ...
   ...
   debugTimer(false);
}

And you will see the timings for that method.
