Reverse Engineer
The Reverse Engineer indicator answers the following question: "What current price would be required to attain an indicator value of X". For instance, you may want to know what closing/last price (on a daily chart) would be required in order for the RSI value to reach 70. Or you might want to know what high price would have to be reached (on a daily chart) in order for the current day's range to exceed its average range over the past 20 days.
