Perception, Although a accumulation was formed and confirmed, after the confirmation of accumulation a pull back happens to absorb the massive orders. This aligned with the fact that eurusd is in a downtrend re enforces the idea of having bearish price action as it acts as a confluence in the specific level of interest were both retail and institutional interest is the same but overall intention is completely different.
In short this is what market manipulation is about, short sellers yesterday at london were right in selling, but the sell was short lived because institutions only sold to enter at new york session with discounted prices for the possible buy before sell at the level of interest(High time frame order block formation) but retail entered for a longer term sell before the institutions finalize their positions. this is what turns great trade ideas into losses, and retail trades into liquidity providers for the market makers
