Key takeaways
- Support levels mark historical price points where buying interest has slowed a decline.
- Resistance levels mark historical price points where selling pressure has capped an advance.
- Classic pivot points use yesterday's high, low, and close in a mechanical calculation.
- These levels are backward-looking descriptions of past behavior rather than future predictions.
What support and resistance represent
Support and resistance are price levels derived from recent trading activity — support marks a level where buying interest has historically been strong enough to slow a decline; resistance marks a level where selling pressure has historically capped an advance. They're descriptive of past price behavior, not a prediction of what happens next.
Descriptive Price Levels in Trading
The classic pivot-point formula
One standard, widely used method calculates these levels from the most recently completed trading session's high, low, and closing price: Pivot = (High + Low + Close) ÷ 3. From there, Resistance = (2 × Pivot) − Low, and Support = (2 × Pivot) − High.
This is a purely mechanical calculation — the same formula applied identically to every company's most recent completed session, with no subjective input.
Pivot-Point Formula Components
| Component | Source Input | Mathematical Function |
|---|---|---|
| Pivot | Most recent high, low, and close | (High + Low + Close) ÷ 3 |
| Resistance | Pivot and most recent low | (2 × Pivot) − Low |
| Support | Most recent high and pivot | (2 × Pivot) − High |
The honest limits of this
These levels are backward-looking by construction — they describe where price reacted recently, not where it's guaranteed to react next. Markets can and do move through both levels, especially around news or results. They're best treated as one data point among many, not a signal on their own.
Monminds computes support and resistance for every tracked company using this exact pivot-point formula from the most recently completed trading session, shown alongside the rest of each company's risk metrics.
Evaluating Support and Resistance
Are the levels derived from recent data?
Confirm that the pivot-point calculation uses the most recently completed trading session's high, low, and close.
Are you treating the levels descriptively?
Remember that support and resistance describe past price reactions rather than guaranteeing future behavior.
Are you avoiding single-indicator reliance?
Treat these mechanical price levels as one data point among many rather than a standalone trading signal.

On NSE and BSE: what to keep in mind
- Daily high, low, and close data from NSE and BSE trading sessions are the standard inputs for these calculations.
- Corporate announcements, news, or earnings releases on exchange portals can cause prices to move straight through support and resistance levels.
- Monminds automatically computes these levels using the most recently completed session data alongside other risk metrics.
Frequently asked questions
Are support and resistance levels predictive?
No. They are backward-looking descriptions of where prices recently reacted, not guarantees of future price behavior.
What inputs are required for the classic pivot-point formula?
The formula requires only the high, low, and closing price of the most recently completed trading session.
Can markets move past support and resistance levels?
Yes. Markets frequently move through both levels, especially around news events or corporate results.
How does Monminds compute these levels?
Monminds applies the classic pivot-point formula identically to every tracked company's most recently completed session.
Editor's note
Monminds Research is an analytics, research-workflow, and decision-support platform — not a guaranteed-returns product, and nothing on this site is personalized investment advice. Charts and examples in this article use illustrative figures, not data on any real company.
The bottom line
Support and resistance levels provide a mechanical, backward-looking summary of recent trading ranges using high, low, and close data, serving as descriptive context rather than market predictions.
