Bullish vs bearish order blocks
Order Blocks & Premium/Discount
Support below, resistance above
A bullish order block sits below price and marks potential support, the last down candle before an up move. A bearish order block sits above price and marks potential resistance, the last up candle before a down move.
It's a zone, not a price
Traders mark the order block's full range, from its high to its low, as the zone of interest, not just a single price. Price returning anywhere inside that range can react.
Traded through means weaker
Just like a fair value gap, an order block that already got fully traded through and closed beyond usually loses its power to act the same way twice.
