This indicator plots the opening range for each of the market sessions.
Users can chose the length of the opening range, as well as change the time for each of the sessions.
This script is based on opening range breakout strategies, which entail taking a long/short depending on which way the price breaks out.
To trade it, we wait for the session opening range to print, and then we enter upon a candle close.
It's meant to be used on lower timeframes, ideally one hour or lower.
It can be used by itself, but it works even better in combination with other indicators, like moving averages.
