Pullback in falling market prices

I feel that the market can go a little higher and then after that we will be ready for a big fall, but we want to take advantage of this.
The market moves up in a channel that can be in two ways, which I have marked with white and purple lines
We have to take our profit from the market step by step
which I have marked with TP
We must be careful to change our stop loss after dealing with each TP
for example
When we reach the TP1 , we need to change the stop loss to the entry point
