Real-time forex quotes: the most-traded pairs, each with a display name.
The feed carries 1,550 pairs in alphabetical order, which is far more than one
response can hold — so this returns the most prominent `limit` of them (majors
first, then by volume), and the response states how many were left out. Pass
`symbols` for specific pairs, or call get_forex_quote for a single one.
Read `note` before summarising: it says how many pairs the slice covers out of
how many exist, so a "top pairs" answer is not mistaken for the whole market.
`volume` on a forex row is a per-venue tick count, not market turnover — FX is
over-the-counter and most pairs report 0. It does not rank the market.
Args:
symbols: Comma-separated pairs (optional; overrides the ranked slice)
limit: How many ranked pairs to return (optional)
