Back testing my Breakout strategy (USDJPY)

I’ve noticed USDJPY sets up for a breakout during the Tokyo session, based on that I thought of this strategy.

Strategy: Breakout Time of Day: Tokyo Session Time Interval: 15 min Risk Management: 1:2, 1:3 Rule: one trade per day

Break & Retest Entry Rules 1. High Volume Breakout 2. Retest of breakout 3. Confirmation candle for precise entry - Stop loss, below last low

Exit Rules 1. Immediate Trend line is broken Or 2. Bobble bottom or top is made

Any tips?
