Fade the gap or chase it? NIFTY opening gaps, tested
NIFTY opens away from yesterday's close all the time. The eternal question: does a gap fill (fade back toward the prior close) or does it run (continue in the gap's direction)? We took every day NIFTY gapped more than 0.3% — 194 of them over two years — and tested both plays: fade the gap (short a gap-up, long a gap-down), or chase it. Enter at the open, exit at the close.
Fading edged it out
Fading the gap won 52.1% of the time and netted +1,328 points. Chasing did the exact opposite — it's the mirror trade, so it lost the same 1,328 points and did it with a bigger drawdown (−3,306 vs −2,150). Over this window, the crowd that bought the excited gap-up and sold the panicked gap-down was, on net, wrong.
Takeaway
On average, NIFTY gaps mean-revert more than they continue — a mild edge for faders. But the margin is thin and the drawdowns real. The signal is a lean to combine with context (news, trend, level), not a standalone system.
