Rate of change (ROC)

সহজ ভাষায় অর্থ

ROC expresses the selected price's percentage change from the value a configured number of bars earlier.

এটি কেন উপকারী

Rate of change (ROC) 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.

XMarketRadar-এ কোথায় দেখা যায়

Look for Rate of change (ROC) in Advanced Chart settings, indicator panels, screeners and technical research for the selected listing and bar interval.

কীভাবে হিসাব বা উৎস নির্ধারিত হয়

For configured period N, ROC = (current selected price / selected price N bars earlier − 1) × 100. It is unavailable when the reference price is zero or the history is incomplete.

ইনপুট, সময়কাল ও একক

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.

ব্যবহারিক উদাহরণ

Illustrative only: a user reviews Rate of change (ROC) over a stated 20-bar or FY2026 period, checks the displayed source, unit and as-of date, and keeps an absent field as — rather than guessing 0.

উচ্চ ও নিম্নের অর্থ

A higher or lower Rate of change (ROC) value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.

ধনাত্মক, ঋণাত্মক ও প্রকৃত শূন্য

Positive and negative Rate of change (ROC) values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.

কখন অনুপলব্ধ

Unavailable (—) means Rate of change (ROC) 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.

সীমাবদ্ধতা ও সাধারণ ভুল

Rate of change (ROC) 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.

বাজারভিত্তিক পার্থক্য

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.
