Why Two Crypto Chart Providers Disagree on the Same Candle

Two chart providers show different highs for the same hour. Before calling one wrong, check what each is actually charting.

Short answer

Two providers disagree on the same candle for checkable reasons: different venue or market (spot vs perp, aggregated vs single exchange), different timezone or candle boundary, open-time vs close-time labelling, different trade filtering (some exclude outlier or off-book trades), different price type (last vs mark vs index), and late corrections. Match venue, market, timezone, convention and price type first; remaining small differences are usually filtering or timing.

Example

Illustrative: provider A shows the 14:00 BTC 1h high at 61,420; provider B shows 61,180. A is a perpetual on one exchange; B is an aggregated spot index. On the same perpetual, B shows 61,410; the 10-point residual comes from B excluding a single outlier print.

Documenting your source

When you share a chart or level, add a short source line: provider, venue, market type, interval, time zone and price type. For example: 'Venue A BTCUSDT perp, 1h, UTC, last price.' That line answers most of the questions that otherwise lead to arguments about whose chart is right.

Conclusion

Match venue, market, boundaries, timestamp convention and price type before calling a candle discrepancy an error.
