When data shows a dash or unavailable
Updated 6 August 2026 · 2 min read · 10 Contents
Plain-language meaning
A dash or unavailable label means verified evidence is absent, unsupported, stale or not computable for that exact field. It is a deliberate honest state, never a rendering defect to ignore, and it is never silently replaced with a guess.
Where it appears #
Unavailable markers appear across quotes, financials, screeners, derivatives, funds, portfolios and official data, usually with a reason or source label nearby.
Step-by-step workflow #
1. Read the unavailable reason or source label. 2. Confirm the exchange and exact listing are the ones you intended. 3. Check the as-of timestamp against the venue's session calendar. 4. Reload once to rule out a transient fetch failure. 5. Check whether the field is supported for that market at all. 6. If a field you saw populated earlier is now blank, report it through Feedback with page, symbol and time.
Worked example #
A newly listed company can show unavailable RSI because 14 completed sessions do not exist yet, while its price is populated. Both states are correct at the same time: the price has evidence and the indicator cannot be computed honestly.
How to interpret the result #
Populated-with-date means evidence exists for that time. Unavailable means evidence is missing, not that the value is zero. A genuine zero is displayed as 0 with its source.
Limitations and common mistakes #
Do not treat unavailable as zero in comparisons, and do not assume a dash means the product is broken: incomplete provider coverage, market holidays, warm-up windows and unsupported market fields all produce honest dashes.
Market-specific differences #
Coverage differs by exchange because official sources, licensing and provider fields differ; an international venue can be provider-required while NSE is fully populated.
