Since 6-February Bitcoin has been moving within a range between $60,000 and ~$83,000. The middle line would sit around $71,500. Going by this measure, any trading above $71,500 can be considered bullish while below we can say Bitcoin's bullish potential diminishes.

BTCUSDT daily stochastic enters oversold region followed by bullish crossover

The stochastic managed to reveal each single reversal first by entering the oversold region followed by a bullish crossover. As soon as this signal appeared, Bitcoin started to rise, 100% of the time.
5-Feb the STOCH hits oversold with a bullish cross and Bitcoin starts to rise the next day, 6-Feb.
23-Feb the STOCH does the same and the higher low on BTCUSDT appears 24-Feb, then a new rise.
27-March the STOCH hits bottom and a bullish cross appears 29-March. Bitcoin started to rise 29-March non-stop.
16-May the STOCH hit bottom and a higher low on Bitcoin appeared 18-May.
19-May the STOCH produced the classic bullish cross and today, 20-May Bitcoin turns green...
Here we can assume, based on this information, that the low is in and we are set for a bullish continuation.

So far this signal has been effective 100% of the time.

This is just one signal of course, there is no doubt that Bitcoin will resume going up.

one thing worth noting is that oscillators like stochastic work best in ranging markets. if bitcoin breaks out of the 60k to 83k range decisively the signal quality may weaken significantly because trending conditions can keep indicators overbought or oversold for extended periods
