How to read NSE candlestick charts

An NSE candle is four prices in one bar: open, high, low and close. Indian desks read those four numbers against the cash session — 9:15 to 15:30 IST — not against a 24-hour crypto clock. Once you see the body versus the wicks, a 15-minute NIFTY chart stops looking like decoration and starts looking like a tape.

Open, high, low, close

The body is the distance between open and close. A green (bullish) body means close settled above open. A red (bearish) body means close settled below open. The thin lines — wicks — are the extremes: high above the body, low below it. A long upper wick after a rally into 15:15 is often leftover supply, not “more upside.” A long lower wick into 9:30 is often leftover demand from the auction open.

Heikin Ashi averages those four prints so the picture looks smoother. Use it for trend context. For entries on BANKNIFTY or a liquid stock, switch back to regular OHLC — you need the real high and low, not a constructed one.

The NSE session is the frame

Pre-open (9:00–9:08) and the 9:15 print set the first range. The first 15-minute candle of NIFTY or BANKNIFTY is a map, not a trade by itself: it tells you whether the open was accepted or rejected. Lunch hours can go quiet. The last hour — 14:30 to 15:30 — is where F&O desks square, hedge, or press. A candle that looks identical at 11:00 and at 15:20 does not mean the same thing.

• Mark previous day high, low and close before the 9:15 open.
• Read the opening range (9:15–9:30) as accepted value, not a breakout until it holds.
• Treat 15:15–15:30 wicks as expiry and square-up noise unless you trade that window on purpose.

What the wick is saying

A wide body with almost no wick is conviction: buyers or sellers walked the price and closed near the extreme. A small body with long wicks is a fight — useful near previous-day high, VWAP, or a round NIFTY strike. Doji and spinning tops are pauses. They are not automatic reversals on an index that can trend for twelve 15-minute bars after a RBI or budget print.

Timeframe that matches the desk

Intraday F&O: 5m and 15m. Swing on cash or futures: 1h and daily. A 1-minute chart will manufacture patterns that do not survive the next auction. If you keep NIFTY 15m and BANKNIFTY 5m on the same desk, you see index bias and the faster beta without flipping tabs.

Indicators sit on top of this structure — RSI and MACD, Supertrend, VWAP — they do not replace OHLC. Read the candle first.
