EMA pair · 9/21
9/21 EMA crossover
on NIFTY & BANKNIFTY.
Fastest standard pair. Used for intraday momentum on 5m & 15m.
The 9/21 EMA combination is the most-used fast pair on Indian-index intraday charts. It reacts quickly enough that crossovers print 1–4 times per session on volatile days, which means edge depends entirely on whether the market is trending or ranging — a classic application for a regime filter.
