RealtimeBulkQuoteRequest

A request to REALTIME_BULK_QUOTES, which returns a current snapshot for many tickers in a single call, up to a hundred of them.

It answers the same question as QuoteRequest — what is this trading at now — but amortises one round trip and one rate-limit charge across a whole watchlist instead of paying both per ticker. It is a premium endpoint, and its snapshots carry extended-hours figures that GLOBAL_QUOTE does not.

Because the endpoint takes its tickers as one comma-joined parameter, forSymbol accumulates rather than replaces — the one place in this package where calling a setter twice keeps both values. See that method for what this means for callers used to the inherited behaviour.
