Too complicated. Too many steps with magic numbers.
Also, stops don't guarantee a price, they just guarantee a sell.

(BTW, it would be useful to post the link to these strategies when you mention them.)

Here's a simpler strategy that delivers 22 times your money in the last 10 years (11/6/2015 - 11/6/2025).

Ready?
Step 1) Buy TQQQ.
Step 2) There is no step 2.

There is a little tweak that delivers 41 times your money in the same time period.

Timing rule:
If QQQ did not have a new 90 day high in the last 90 days, sell.
Every day, after the close:
1) See if this day's close is the high close of the last 90 days.
2) See if any of the last 90 days was flagged as a 90 day high.
3) If yes, buy/hold. If no, sell.

There were 20 trades (10 sells, 10 buys) in that period.

Since TQQQ inception:
