A higher high followed by a lower low: sell the retest of the left shoulder.
The Quasimodo (also called over-and-under) is a reversal pattern related to head and shoulders. In the bearish version, price makes a high (the left shoulder), a low, then a higher high (the head) that takes the left shoulder's buy stops, and then breaks below the low between them, making a lower low. The left shoulder's level is the Quasimodo level (QML); price often comes back up to it, and that retest is the short.
It comes from retail forex price-action circles and is also used in Malaysian SnR. Its originator isn't well documented.
