Trades

Each live trade contains only:

{
    "price": 1927.5,
    "size": 0.25,
}

trades = history.source("btc@trades@bulkf")
latest = history.source("btc@trades@bulkf", 0)

The selector already identifies the symbol, exchange, and provider. Timestamp and aggressor side remain internal.

Trade records are live-only and cannot be used in backtests. See Trades Source.
