Finding high and low between a date range

 

Hi

I'm using EA(Robots) on demo account for practicing and evaluating the robots. I have a doubt, I need to find the High and Low between the buy and sell of the trade.

This is just to optimize my stoploss setting on EA. Could some body give an idea of how to get this in a simple way. I know the the round about way to plot the chart for buy and sell points and visually identify the high and low between them.

Please let me know
