What it is
A bear flag is a sharp fall (the pole) followed by a short, tight drift sideways or up (the flag). Sellers are pausing; the break below the flag shows them pressing again.
How we detected it
The pole falls at least 7% from a high to a low over 3 to 10 days. Then, for 4 to 15 days, the flag stays above 0.5% below the pole low, wins back no more than half the fall, and ends no more than 0.5% below where it started. The breakdown is a close below both the flag low and the pole low. We count the breakdown day.
How traders read it
The flag often looks like a recovery, which is what traps buyers. Traders wait for the close below the flag and keep a stop above the flag high.
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 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.
