This script highlights when price violates the highest high or lowest low within the user's selected lookback period, with the caveat that it occurs during the GLOBEX session. The script is designed to work exclusively with the trading hours for CME and CBOT Equity Index futures. I'm planning to make a more customizable version down the line.
My reasoning...
This script is a combination of my overnight fakeout script and bollinger band color bars. It's designed to be used on CME/CBOT Equity Indexes during their GLOBEX session. It uses the built in Bollinger Band script and highlights bars that exceed the upper/lower bands during the overnight session.
