This tool allows you to quickly identify the macro and micro trend's direction and enter and exit position at a more favorable price.
When the pink lines are angled up you should look for a long position and enter only when the candles are colored green. And when the pink lines are angled down you should look for a short position and enter only when the candles are colored red.
This tool is only meant to be a practice tool and should be used to train your eye on candle movements to gain a sense of when you should enter/exit.
Practice is what differentiates a good trader and a bad one.
