What is RSI (Relative Strength Index)?
Relative Strength Index compares average gains to average losses over a lookback (commonly 14). Readings above 70 and below 30 are traditional extreme zones — not automatic reversal signals.
Formula
Above 70 = overbought; Below 30 = oversold
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 RSI (Relative Strength Index) shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
Nifty at 24,300 printing RSI(14) above 70 on the 15-minute chart after a gap-up open often coincides with mean-reversion toward the session VWAP — tag “RSI OB” in your journal and review hit rate separately from cash hours.
Reliance Industries perspective
Reliance at ₹1,300 with daily RSI near 32 after a three-day slide from ₹1,360 is oversold on Wilder’s default — many swing traders wait for a close back above 35 with volume before entry.
Bank Nifty futures perspective
Bank Nifty futures at 55,000 holding RSI above 68 through 10:30 IST sometimes marks exhaustion before lunch compression; pair with relative volume, not RSI alone.
| RSI zone | Common misread | Journal habit |
|---|---|---|
| > 70 | Must sell | Tag trend vs mean-reversion setups |
| < 30 | Must buy | Note support structure separately |
| 50 cross | Trend filter | Pair with higher timeframe bias |
