cross exchange
Queries Binance, Coinbase, Kraken, OKX and Bybit in parallel for one BASE/QUOTE pair, four seconds per exchange. An exchange that does not answer drops out with a stated reason and the call stays valid; venues_failed lists them. oldest_age_ms is mandatory and states the age of the oldest quote that entered the comparison, because differences taken from unequal points in time are the most common error in this kind of table. With an optional size the visible book of each exchange is walked as.
