A prominent wick left behind when price sweeps beyond a swing point and reverses hard — the wick itself is the block, and it signals reversal, not continuation.

It doesn't always look like this
Rejection block vs. order block — an order block is the last candle's body before a continuation move. A rejection block is the wick left behind by a reversal. Different shape, opposite meaning.
The wick can be on either candle — sometimes the sweep and the reversal happen in the same candle (like above); sometimes the sweeping candle closes weak and the very next candle does the sharp reversal instead.
Works both directions — a bullish rejection block sweeps below a low and rejects upward. A bearish one mirrors it: sweeps above a high and rejects downward.
Already tested intrabar — on a lower timeframe, the retest into the wick can already be tapped and reversed before the HTF candle closes.
