Red Boxes are Order Blocks. In this case you can see the next significant Monthly Order Block.
The Blue Box was a Breaker used to break old highs and take liquidity / move price higher - you can see how this played a significant role later on.
The single red lines are simply significant levels of liquidity for price to reach.
There is no guarantee we are already heading up there for liquidity and that we have completed selling.
This is just for educational purposes.
