My short answer is yes I will wait until the price action crosses above the 200ma before I enter TZA.
However, IF the 9ma and the 20ema have both unmistakably turned up, the 9ma is above the 20ema, and the PPO has also unmistakably turned up, THEN I may take a risker entry opportunity and buy before it actually crosses above the 200ma.
Now for a very high risk ETF like BOIL, I will absolutely wait for the price action to get above the 200ma before I enter.
BOIL today printed a full candle stick above the 9ma, the PPOcrossed upward and printed a green histogram bar above the 0.0, BUT all this occurred below the 200ma.
I did not enter BOIL today.
Paul Tudor Jones once said 'Only professional trader make money below the 200ma'. GLTY
