What is EMA (Exponential Moving Average)?
EMA applies exponential smoothing — recent bars matter more than SMA.
Formula
EMA Calculation: Multiplier = 2 / (Period + 1) EMA = (Price × Multiplier) + (Previous EMA × (1 - Multiplier)) Example: 10-day EMA Multiplier = 2 / (10 + 1) = 0.1818 (18.18%) Yesterday's EMA: ₹100 Today's Close: ₹105 Today's EMA = (105 × 0.1818) + (100 × 0.8182) = 19.09 + 81.82 = ₹100.91 EMA moved from ₹100 to ₹100.91 (SMA would move less with same data)
Indian market context (NSE)
Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how EMA (Exponential Moving Average) shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
EMA on Nifty (24,300): on the 15-minute chart, combine with session VWAP and 9:15–10:00 liquidity — index ema signals misfire on expiry Tuesdays without volume confirmation.
Reliance Industries perspective
EMA on Reliance at ₹1,300: daily vs hourly settings diverge around results and ex-dividend dates; note corporate events in journal when ema readings spike.
Bank Nifty futures perspective
EMA on Bank Nifty futures (55,000): first-hour signals differ from post-14:30 behaviour; avoid standalone entries when banking names lead the move.
