new trader utilizing flow methodology

I have bias to believe that price for the GBP/USD will slightly fluctuate or reverse with my designated zones. this is due to levels within the blue and red zones where there I believe may be a imbalance, and price will flow, or reverse in order to go to other levels. My trades placed are limit orders, and aim to capture these reversals with low risk, and moderate-to-high rewards. This strategy is used with analyzing the current trend momentum, blue levels and red levels indicating imbalances we aim to exploit for low risk trades.

At the moment, I am testing a new strategy of my existing, seeking to capture and exit 3 trades during their reversals.
