Distinguish an expected timing difference from a data error across the board, weekly candles and settled-week results.

Read the price session, weekly anchor and publication time together. A refresh timestamp alone does not establish freshness.
US regular-session closes carry the US trading date, while a snapshot may publish the following morning in Korea. Reading Monday’s US close on Tuesday in Korea is expected. Identify the price’s session before checking whether publication occurred today.
The board’s regular-session close, the last weekly candle and quotes in the separate leverage calculator need not share an observation time. Treating the board as an intraday live feed causes misleading comparisons. Check each view’s source and timestamp first.
When the next weekly band is set, its anchor and reference close can coincide at 0σ. The new week’s displacement has not yet been observed. Last week’s movement still exists and must be evaluated against its own anchor and width.
A weekend chart showing the completed week needs that week’s band. Overlaying the newly established range on old candles cannot evaluate what the options market expected at the time. Match the candle period and band period before interpreting a breach.
Historical closes can exist without the corresponding anchor’s weekly width. SigmaRange leaves that result empty rather than filling it using current implied volatility. Using present expectations as if they were known in the past distorts historical position and performance.
This week’s +0.5σ and last week’s +1.0σ may use different reference prices and dollar widths. A change in normalized position is not the same as a change in dollar distance. Compare prices, anchors and widths together.
The GEX panel carries a separate options-data date. Do not assume it belongs to the same information set as the latest candle. A historical signal evaluation needs both the record date and its actual publication or availability time.
Support and resistance labels describe selected gamma-related price levels. They do not guarantee a reversal. Reversal predictiveness is unvalidated; use these levels as context to corroborate or contradict other evidence.
