Step 1: confirm the trend H4 M30 M15
Step 2: wait for the price pullback to liquidity sweep, BSL, SSL, SMT at important areas such as OB, FVG, pivot point, etc.
Step 3: observe price action (rejection candle, LW...)
Step 4: confirm with indicators on M5 M15 of this system.
Where is the price compared to daily+weekly VWAP, daily+weekly pivot point.
Step 5: Decide whether to enter trade or not.
I only look for entries within 2H from the opening of the London, US sessions.
You should trade pairs that are suitable for each session.
