Angle of the 21ema and the strength of a Bull Move

Just experimenting with the angle of the 21ema and the likely move out of it.

I have seen about 4 different angles and 4 different bull moves

Strong Explosive Moves with 70-75 degrees

Decent Moves with 60-65 degrees

Grindy and choppy up moves with about 45 degrees

Most likely a pullback with 10-25 degrees
