new here, can someone confirm or dismiss what i got from all that i read.

In this image, on M30 i would wait for 1 and only then wait for 2, 3, 4 or 5 (red inside the white dots).
Now i would take the trades (sell) on M5 with the red dots after 3 and 5 when everything is red. I would not take the ones after the 2 and 4 because there is still lots of blue.

I know i'm simplifying, but Is this it?
Thanks.
