Missed opportunity on GBPUSD 1hr session during London Open

Welcome today to my 1H trading session during the London open.. Trading on 1min can be tasking because it require your undivided attention which I give but end up missing the only 1 opportunity for the day. I'm suppose to draw the possible rejection level before it happen, 1mins timeframe won't give you time to hesitate on what to do next. So automatically, 1min timeframe frame will build your execution skills.

Result so far!

1st week- 5% drawdown (5 loss)
2nd week- 2% drawdown (1win (3r))
