L5.2 — Higher-Probability BOS: Quality Filters

Not every BOS is equal. A BOS from a strong, impulsive move carries more weight than a BOS generated by a slow, grinding candle that barely clears the prior high. The impulse quality of the break is a useful filter for how much confidence to place in the subsequent continuation setup.

Quality filters for a BOS: (1) the break candle is large relative to recent candles, suggesting genuine momentum; (2) the candle closes well beyond the swing point rather than just piercing it; (3) the break is accompanied by a structural sequence that supports it (prior higher highs and higher lows for a bullish BOS). A BOS that fails all three of these filters is a weak signal at best.

BOS Quality Filters — Chart ViewNot all breaks are equal. Strong BOS = impulsive body through. Weak BOS = no conviction.

The practical application: after a high-quality BOS, the pullback to the broken level is the entry opportunity. After a low-quality BOS, the pullback should be watched with more caution — the probability of the level failing on the retest is higher. Setting a minimum quality standard for the breaks you act on is a form of trade filtering that improves selectivity without adding indicators.
