I use this chart also to help signal a change in momentum…when the stoch 144 breaches 50 is a buy signal. But again, with any indicator, it’s not “perfect”.
The 144 ONLY works on the 15 minute…

Ideally want to see the stoch riding above 70 when the momentum is “bullish”
Then can confirm the 15 minute with the 60 minute chart:

Is this a BULL FLAG?

These ETFs are designed to take your money…DO NOT PLAY unless you can read these indicators like a second language. Also, the 13/34 MA crosses are invaluable in determining the direction of momentum. Good luck!
