How we detected it
We find the last up-swing: the highest high from 45 to 3 days ago, and the lowest low in the 40 days before it (at least 5 days earlier). It must have risen at least 8%. The lowest low since the swing high is nearer the 50% level than the 38.2% or 61.8% levels, and within 4% of the swing’s size from it. The close is above the 50% level and more than 1% above that low. We count the first day this is true.
How traders read it
Halfway is a natural place for a trend to resume, but not a guarantee. Traders look for a reversal candle there and keep a stop below the pullback low.
A signal is a probability, not a promise
Even the most reliable signal in this study was followed by the opposite move 37% of the time. A signal tilts the odds; it doesn’t decide the outcome.
Signals work better when they agree with the trend and with each other. Whatever the signal, decide your stop-loss before you act.

How is “Fibonacci 50% retracement” defined here?
We find the last up-swing: the highest high from 45 to 3 days ago, and the lowest low in the 40 days before it (at least 5 days earlier). It must have risen at least 8%. The lowest low since the swing high is nearer the 50% level than the 38.2% or 61.8% levels, and within 4% of the swing’s size from it.

How these numbers were made
We ran the same signal detector MarketSeekho uses to grade players over every trading day of 187 NIFTY 200 stocks, Jan 2021 to Oct 2025, using NSE end-of-day prices (1,54,833 stock-days). We counted the first day a signal appeared, then ignored the same signal on the same stock for 12 trading days so results don’t overlap. Windows with splits, bonuses or trading halts were left out.
“Any day” is the baseline: the same measure after every day in the data, signal or not. It matters because 2021–2025 was mostly a rising market, so stocks were higher after 12 days more often than not anyway. Past results don’t predict future ones, and this is not investment advice.
