One condition which could indicate a reversal is the dmi - (red line) reaching the 40 line (purple horizontal line) on the 5 day time frame. Looking at the history of dmi, the dmi - reaching the 40 line/level has been indicative of the bottom being in. Nov 2018, March 2020, both bottoms coincided with the dmi - reaching this level. While it's not necessary, this is one of the signs I'm looking for. It doesn't mean btc price will rocket to the moon straight away once that level's hit, what would be another good sign, following that level getting hit, would be the dmi + and dmi - (blue and red lines) crossing, and then both remaining close, flat, crisscrossing one another for a few weeks, or months. That would be accompanied by the flat price action which often precedes a reversal, not unlike after the low was put in in Nov 2018...it took a while.
