How to use this calculator effectively

Why pivots matter

Classic pivots turn prior session H/L/C into objective support/resistance bands for the next session.

Use them as reference zones—combine with trend/volume for confirmation.
Pick the right timeframe
  • Daily pivots: intraday trading.
  • Weekly/Monthly: swing bias.
  • Align longer TF trend, execute on a faster TF.
Confirm levels
  • Watch Volume-by-Price or high-volume price zones.
  • Look for closes/strong reactions at P, R1/S1.
  • Prefer confluence (trendline, MA, round number).
Stops & targets
  • Place stops just beyond the level (or use ATR-based buffers).
  • Plan R:R with your stop distance before entry.
Pre-trade checklist
  • Trend on higher TF agrees with your bias
  • Level has volume/structure confluence
  • Stop placed beyond level (or ≥ 1×ATR)
  • R:R meets plan (e.g., ≥ 1:2)

Support & Resistance — quick guide

What are they?

Support is a floor where buyers step in. Resistance is a ceiling where sellers show up. Use them to time bounces, retests, and breakouts.

Why it helps
  • Plan entries/exits near objective levels
  • Cleaner stops & position sizing
  • Quick context for intraday swings
Formulas (Classic)
  • P = (H + L + C) / 3
  • R1 = 2P − L  ·  R2 = P + (H − L)
  • S1 = 2P − H  ·  S2 = P − (H − L)

Excel quick-start
