I tried to explain it to you. You don't seem to understand. 8-8.4 buy zone was for a complete correction scenario which is still valid. As you can see price bounced @ 8200.

If 8200 is breached the scenario is invalid. It's not that hard to understand.

There is no 100% guarantee, I usually post the most probable scenario at the time of posting. I usuall have 3-4 different scenarios in the back of my mind for when the invalidation point is reached.
