So I've been back testing and I've decided to do this. I will try to trade journal this here.
QQQ had the 8/21 EMA cross on the daily on Friday.
I scaled into TQQQ on Friday and Monday with a cost basis of 20.28.
My plan is to ride this the 8/21 EMA cross back on the daily. I plan to scale out along the way on any big rips and potentially sell calls as well (work had me away from my computer this morning or I definitely would have sold calls). But I will be fully out for sure when the 8/21 EMA cross to the downside.
This is a longer term swing... in my back testing, the EMA has triggered up or down 26 times over the last 2.5 years.
