PhantomFlow RangeDetector analyzes the current price action of the market and draws ranges depending on the minimum number of bars in the zone of one candle you specify. Each range is colored depending on the closing direction of the candle outside this range. Accordingly, in trend trading, it is advisable to look for long trades from the green zones, and short trades from the red zones (with standard color settings).
If you have a basic understanding of the market context, you can consider such zones in a mirror retest to find trades with higher RR.
