+
+* To sandwich, a searcher will watch the mempool for large DEX trades.
+* A searcher can calculate the approximate price effect of this large trade and execute an optimal buy order immediately before the large trade, then executing a sell order immediately after the large trade (selling it for the igher price caused by the large order).
