What it is

When price falls clearly below the 61.8% level, it has given back most of the previous rise. Sellers have overwhelmed the buyers who usually defend this zone.

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 close is below the 61.8% level by more than 2% of the swing’s size, so more than 63.8% of the rise has been given back. We count the first day this is true.

How traders read it

Many traders treat this as the point where the uptrend has failed and exit there. It does not say price must reach the swing low, so they watch how it behaves at the 78.6% level and the low.

How to use this

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 “Break below Fibonacci 61.8%” defined here?

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.
