What date was it?

Wick on a candle is included in the gap analysis. The gap analysis on the candles includes the high and the low, not much to do with open and close (as with full candle).

For an up gap to form, the low price after the market closes must be higher than the high price of the previous day. Up gaps are generally considered bullish.
A down gap is the opposite of an up gap; the high price after the market closes must be lower than the low price of the previous day. Down gaps are usually considered bearish.
