Window (gap)
A gap between two consecutive candles where no trading occurred — in Japanese candlestick theory, windows act as support/resistance the market tends to return to.
In Japanese candlestick terminology, a window (or ku) is a price gap between consecutive candles — a zone where no trading took place. A rising window (bullish gap) occurs when the current candle's low is above the prior candle's high; a falling window (bearish gap) is the reverse.
The old Japanese saying is "prices return to close the window" — gaps tend to act as magnets. A rising window acts as support on subsequent pullbacks; a falling window acts as resistance on subsequent rallies. In reversal patterns like the Abandoned Baby, the gaps around the star candle are what make the pattern significant.
Example
After a strong earnings beat, a stock gaps up and never fills the gap over the next three weeks. When price finally pulls back to the gap zone, buyers step in again — the window held as support exactly as the pattern implies.
