Honestly I don't think it would be worth the effort, and would be unreliable. If it is possible then most would offer multiple hundreds of % returns, but it might be pie in the sky stuff. Possibly a weekly reversal pattern after a long term low, don't know.
If I were to look into it, I'd be starting with volume, volume is there somewhere as someone always knows something. Then the higher low, but we will always run into the problem of not actually being a bottom. Lots of these higher lows etc. turn into the abc correction then resume downwards.
The current setup after the cross is much better risk/reward IMO, especially when we see those momentum indicators rising.
