compression_zones

// Compression Zones: compression zones from a 0..80 score (ATR compression, ADX chop, volume dry-up where real volume exists, impulse-in, historical S/R reuse) plus range compression and boundary-touch structure; value = score; extra: range_atr, in_zone, zone_high/zone_low, upper_touches, lower_touches, read (bull/bear pressure or continuation), armed, hist_reuse; alerts bull/bear_breakout (close beyond the zone edge within watch_bars after a zone of at least min_zone_bars, with body, close position and volume checks; prefix = expected move)
