Technically we see price broke a clear downtrend and made its first HH (higher high).
Right now is making a shallow pullback to a strong S/R and from my point of view will continue the rally.
Convergence on AO shows the expected next price movement.
I will take profits and add to my long positions here.
There is hole trading system behing called Convergence-Divergence. In simple words: after a clear downtrend first convergence is the confirmation for a trend change. Then i wait for a pullback because sooner or later price should reach the level of first convergence and exceed it (16.04). So this gives me the direction of next trade and i can focus only on longs.
Combining this with support and resistance and candles i think this is a good entry for a long.
