Support & Resistance — A Practical Guide

Educational
What are they?

Support is a floor where buyers step in. Resistance is a ceiling where sellers emerge. They help spot reversals and breakouts.

Why they matter
  • Plan entries/exits near key levels
  • Place smarter stop-losses
  • Read trend continuation vs. failure
How calculators find levels
  • Classic Pivot Points (H/L/C)
  • Dynamic Moving Averages
  • Fibonacci retracements

Excel setup

Inputs: High, Low, Close of the period.

Pivot (P)(High + Low + Close) / 3
R1(2 × P) − Low
R2P + (High − Low)
S1(2 × P) − High
S2P − (High − Low)

Worked example (NSE)

Inputs: High = 500, Low = 450, Close = 480 → P = 476.67
Pivot (P)
476.67
R1
503.33
R2
526.67
S1
453.33
S2
426.67

Trading playbook

Three common ways traders use levels in day-to-swing setups:

Range trading
Buy near support, take profits near resistance; fade the extremes while the range holds.
Breakout confirmation
Enter on strong break and hold above resistance; look for volume/RSI confirmation.
Risk control
Place stops just beyond the level you’re leaning on; reevaluate if reclaimed decisively.

Benefits

  • Objective reference points (less emotion)
  • Fast, repeatable calculations
  • Cleaner stop placement and position sizing

Not just for stocks

  • Forex: time entries on volatile pairs
  • Commodities: manage swings in gold/crude
  • Crypto: structure trades in high-volatility regimes

Common mistakes to avoid

  • Ignoring trend, volume, and news context
  • Treating levels as static—update as price evolves
  • Relying only on history—blend with real-time signals

Backtesting & next steps

Validate rules around bounces, breaks, and retests using historical data before going live. Pair S/R with volume, momentum, or market breadth for higher-quality signals.

Bottom line

Quantify key zones, manage risk, and make more disciplined decisions in any market regime.
