Bullish Long Island Continuation Pattern
Long islands are continuation patterns, which means that if prices before the pattern are in an uptrend, then prices should continue after the pattern upward. Therefore, if prices before the pattern are in a downtrend, then prices should continue after the confirmed pattern downward. A bullish long island continuation pattern occurs when prices gap up and there is a consolidation period above that gap and then another gap occurs at the end of the consolidation upwards; prices are then expected to continue higher.
Bearish Long Island Continuation Pattern
A bearish long island continuation pattern occurs when prices gap down and there is a consolidation period below that gap and then another gap down occurs at the end of the consolidation period; prices are then expected to continue lower.

The averaged maximum gain for bullish long islands is 31% before any 20% correction occurs;

Bullish Long Island Continuation Pattern Chart Example
The chart of the Energy SPDR ETF (XLE) shows an uptrend with a long island continuation pattern during the uptrend. Prices rose prior to the gap up. Prices gapped up and then prices consolidated for three weeks, then prices gapped up again, continuing the prior upward move.
Bearish Long Island Continuation Pattern Chart Example
The chart above of Coca Cola Company (KO) shows a three month dramatic decline with a long island continuation pattern in the middle of the move downward. Prices gap down, then prices follow with a weeklong downtrend that creates the "pole" portion of the pennant pattern. Prices then ascend forming the pennant; however, prices fake a move upward before doing what is expected with the pennant pattern by moving downward. The downward move is accentuated by a gap down, completing the long island continuation formation.
