This is Stochastic ( on a monthly ) , with specific settings I'm using.
By definition under the 20 level for the Stochastic means oversold.
As we could see the last bottom was exactly below the 20 level.
Currently it looks like #bitcoin will get rejected from the downtrend line , having the last crash and the Stochastic will get below 20 .
Then going back above 20 will mark the new bull market for #crypto
