TickFeed

interface TickFeed : AutoCloseable

Pull-based source of Ticks.

Implementations: HistoricalTickFeed (in-memory), CsvTickFeed (CSV files), ConcatenatedTickFeed (sequential merge), MergingTickFeed (k-way merge by time), RangeClippedTickFeed (date-window filter), MockTickFeed (deterministic synthesizer). Live vendors implement TickFeed too — the backtest and live runtime use the same shape.
