Snapshot cadence and timestamps
Research is built from snapshots taken at intervals, and each quote shows its timestamp. Subscribers should not expect a streaming, tick-by-tick feed. A quote can already be stale by the time you view it.
After-hours and last-session research
Outside market hours, saved last-session research can be shown. Its timestamp indicates when it was captured, and option quotes can differ materially at the next open.
Quotes are not fills
A displayed bid or ask is a research input. Your broker's price, your order type and market movement determine your fill.
Coverage
Coverage starts from an index-based universe and major stock-index ETFs, adjustable with symbol additions and exclusions. Not every contract passes liquidity filters, so some tickers may show no candidates.
What public pages show
This public site contains no live market data. All examples are hypothetical, and one chart screenshot is explicitly historical.
