Thanks for detailed response. I definetly understand changing over time, rules and chart settings. Ive lost count on versions and charts that I have gone thru over time.
I like your idea on the 200MA bias on which PPO is favored.
Regarding the BIG 3 index charts:
One rule that has served me pretty good on Daily charts . Dont short above a 50SMA or if it is RISING.
There are charts that are exceptions but generally I heed that rule. Another rule when long, is if price closes below the 10ema, wait for next day and sell if the prior day LOD is breached.
