The same asset can print different prices on different venues, and a tokenized stock can drift from its listing while the listing is closed. Before drawing a level to the cent, this check asks whether the price is one the wider market agrees with.
get_candles says which source its candles come from. Name it in the answer.compare_assets over the same window for the asset and a close relative (a token and its wrapped form, a tokenized stock and its sector ETF): a gap that opens and closes repeatedly is a basis, not a signal.level for a level both venues agree on, labelled with the venues (OKX + other).zone kind range between the two venues' prices where they disagree, labelled Basis.marker on a single-venue wick, labelled Venue wick.The check is stale as soon as either venue moves; re-read it with fresh candles when the analysis continues later.
Do not compare different timeframes or candle closes in different time zones. Differences of a fraction of the spread are noise.
