I have not yet bought TZA. I will buy when a full candle stick prints above the 9ma on the daily chart, and a green histogram bar prints above the 0.0 on the PPO. Not there yet. Still watching/waiting.
I will hold a position until a candle stick closes below the 9ma, and a orange histogram bar prints below the 0.0 on the PPO.
Look at the KOLD chart below as a text book example of these in and out signals on the dates I bought in and sold out.
I am no longer attempting to optimize or maximize, just swing and get out. Rinse and repeat. Some swings are better than others. GLTY
