This indicator has 3 options in the "Format" settings area for each of the three major futures
contracts. It is built this way because Tradingview does not allow you to build multiple indicators into one script. The best way to use this tool is to apply this indicator three times, check the box for each exchange/market, add labels, and then save it as one of your chart layouts.
