To trade supply zones profitably, focus only on fresh zones where price dropped sharply then weakly retraced—these have the highest reversal odds. Demand strong rejection candles (long upper wicks) showing sellers aggressively defending the zone. Ignore old, overtested zones—they’re traps. Confirm with volume: high selling volume on the initial drop and weak volume on retests signals a high-probability reversal. Always align zones across higher timeframes for explosive setups. Take partial profits quickly, and never let a winning trade turn into a loser—real supply zones reject price fast and decisively.
