The third candle is a black candle that opens within the body of the second candle and closes within the gap between the first and second candle.

Downside Tasuki Gap:
The market is in downtrend. The first candle of the formation is a black candle, followed by another black candle that has gapped below the low of the first candle. The third candle is a white candle that opens within the body of the second candle and closes within the gap between the first and second candle.

A xts object containing the columns:

`UpsideTasukiGap`	TRUE if Upside Tasuki Gap pattern detected
`DownsideTasukiGap`	TRUE if Downside Tasuki Gap pattern detected

The function filters patterns that look like tasuki gap patterns, without considering the current trend direction. If only upside tasuki gaps in uptrends should be filtered, a external trend detection function must be used. See examples.
