Support and resistance

Support and resistance label price areas where prior trading behaviour is studied; they are not guaranteed barriers.

Plain-language meaning

Support and resistance label price areas where prior trading behaviour is studied; they are not guaranteed barriers.

Why it is useful

Support and resistance is useful as descriptive evidence when it is compared on the same definition, source, period, unit and exact listing. It is one input to research, not a verdict.

Where it appears in XMarketRadar

Look for Support and resistance in Advanced Chart settings, indicator panels, screeners and technical research for the selected listing and bar interval.

How it is calculated or sourced

Support and resistance is sourced or derived according to the definition shown above and the screen's disclosed provider, inputs, window and as-of time. Missing required inputs produce an unavailable result.

Inputs, period and unit

Read the disclosed inputs or source, observation period, bar interval, unit, native currency and scale. A value without its source and as-of context is incomplete; unlike units must not be combined.

Worked example

Illustrative only: If price repeatedly traded near ₹95 and reversed, a researcher may mark ₹95 as an area of prior support; a later trade at ₹94 shows it was never a guaranteed floor.

What high and low mean

A higher or lower Support and resistance value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.

Positive, negative and genuine zero

Positive and negative Support and resistance values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.

When it is unavailable

Unavailable (—) means Support and resistance is absent, unsupported, stale under the screen's rules or not computable from verified inputs. It must never be converted to zero or a neutral signal.

Limitations and common mistakes

Support and resistance may differ by provider definition, observation time, instrument and venue. Common mistakes are dropping units or dates, comparing unlike scopes, and treating a missing value as zero.

Market-specific differences

The concept is used across all supported markets, but currency, price scale, session calendar, source field and regulatory definition can differ. XMarketRadar preserves the exact exchange context.
