Pattern log

Time is when the pattern's last bar closed. "Followed through" = how often price closed in the pattern's direction 6 bars later, versus after any bar, on NIFTY history. Patterns are descriptive; none of them showed a reliable edge in testing.

Planning tool only: you place the orders yourself. Probabilities are market-implied, not a forecast. Stops: a premium stop (% or price) is turned into the spot level where the option's model price reaches it; a spot stop is exact. The curve assumes a leg is stopped out when expiry spot is beyond its trigger, so a whipsaw through two stops is shown by "Loss if all stops hit".
