Today's sell off ( a much needed sell off to bring in fresh new buyers) bounced and settled just above the 20EMA. This 3rd new upward trend after the decline in April
is still in it's beginning phase and so I don't suspect this will be transitioning into a downtrend this soon. I would recommend adding/starting positions close to the 20ema.
The tricky part is in between uptrend and downtrends and to notice significant price action under/over 20 EMA
that doesn't come back up/down using this strategy.
