leg_conviction

// Leg Conviction: each confirmed pivot-to-pivot leg scored 0..100 from speed (ATR per bar against speed_ref), cleanliness (share of closes in leg direction) and volume gradient (later vs. earlier half; weight 0 without real volume); value = last up-leg conviction, secondary = minus last down-leg conviction; extra: bull_last, bull_prev, bear_last, bear_prev, pivot_price on alert bars; alerts bear/bull_conviction_divergence (new price extreme on a weaker leg, prefix = expected move)
// Defaults of "leg_conviction" (see the indicator reference)
