A few conditions create genuine difficulty for this type of strategy:
Data releases in line with consensus, when actual figures match expectations closely, directional moves are often limited, and entries may not triggerrnWhipsaw reactions, sharp moves in one direction that reverse quickly, can catch entries on the wrong side before the stop has time to protect the positionrnThin liquidity windows, certain session overlaps, and regional holidays reduce market depth, making execution quality unpredictable even on normally liquid pairsrnMultiple simultaneous releases, overlapping data from different economies, can create conflicting signals, making the initial move difficult to read accuratelyrnrnUnderstanding these limitations doesn't make the strategy less viable; it just sets more realistic expectations about when conditions are favorable and when they're not.
