After price broke structure to the upside, it reacted off a higher timeframe supply which it used to retrace back towards the initial expansion that left behind a clean OB with an imbalance. Price then formed liquidity at both the top of the expansion and above this OB and is now looking to take it out with the assistance of the long term OB to continue to the upside and take out liquidity at the top too. NFP to possibly fuel this move too.
