Intraday Gap Fill Probability Calculator in India
The intraday gap fill probability calculator helps traders estimate how likely it is that a stock will fill its opening gap during the trading session. Gap trading is a popular intraday strategy in the Indian stock market, especially in NSE stocks that open sharply higher or lower due to overnight news or global cues.
However, not all gaps get filled. Many traders enter blindly, assuming every gap will close, which often leads to losses. This calculator introduces probability-based thinking to gap trading.
What Is a Gap in Intraday Trading?
A gap occurs when a stock opens significantly higher or lower than the previous day’s closing price. Gaps are usually caused by:
-
Global market movement
-
Earnings or news events
-
Institutional activity
What Is Gap Filling?
Gap filling means the price moves back to the previous day’s close during the same trading session. Small gaps have a higher probability of filling, while large gaps often continue trending.
