What is ADX (Average Directional Index)?
Average Directional Index quantifies trend strength on 0–100. High ADX suggests strong trend; low ADX suggests chop — regardless of up or down.
Formula
Below 20 = no trend; Above 40 = strong trend
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 ADX (Average Directional Index) shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
ADX on Nifty (24,300): on the 15-minute chart, combine with session VWAP and 9:15–10:00 liquidity — index adx signals misfire on expiry Tuesdays without volume confirmation.
Reliance Industries perspective
ADX on Reliance at ₹1,300: daily vs hourly settings diverge around results and ex-dividend dates; note corporate events in journal when adx readings spike.
Bank Nifty futures perspective
ADX on Bank Nifty futures (55,000): first-hour signals differ from post-14:30 behaviour; avoid standalone entries when banking names lead the move.
| ADX zone | Market character | Strategy fit |
|---|---|---|
| < 20 | Range / chop | Mean reversion, smaller targets |
| 20 – 40 | Developing trend | Breakout continuation |
| > 40 | Strong trend | Trail stops; avoid fading |

Moving Average Convergence Divergence plots the gap between two EMAs, a signal line, and a histogram. Traders watch crosses and momentum fades for timing — always within a higher-timeframe bias.
A moving average is the average price over N bars, recalculated each period. Simple (SMA) weights periods equally; exponential (EMA) weights recent prices more.
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.
FAQ
What is ADX indicator?
ADX measures how strong a trend is, not its direction. It ranges from 0-100. Below 20 = weak/no trend. 20-40 = developing trend. Above 40 = strong trend. Above 50 = very strong trend.
How do you read ADX?
ADX below 20 means ranging market—use range strategies. ADX rising above 20 signals trend emerging. ADX above 40 means strong trend—use trend-following strategies. Direction comes from +DI and -DI.
What are +DI and -DI?
+DI (positive directional indicator) measures upward movement. -DI (negative directional indicator) measures downward. When +DI is above -DI, trend is up. When -DI is above +DI, trend is down.
What ADX settings should I use?
Default is 14 periods. Shorter (7-10) is more responsive but noisier. Longer (20-25) is smoother but lags more. 14 works well for most timeframes and markets.
How do you trade with ADX?
Use ADX as a filter. Only take trend trades when ADX is above 20-25. Avoid trend strategies when ADX is below 20. Combine with +DI/-DI crossovers for direction signals.
