Fields

time_bars_build_with_no_updates: bool

If time bar aggregators will build and emit bars with no new market updates.

time_bars_timestamp_on_close: bool

If time bar aggregators will timestamp ts_event on bar close. If False, then will timestamp on bar open.

time_bars_skip_first_non_full_bar: bool

If time bar aggregators will skip emitting a bar if the aggregation starts mid-interval.

time_bars_interval_type: BarIntervalType

Determines the type of interval used for time aggregation.

• LeftOpen: start time is excluded and end time is included (default).
• RightOpen: start time is included and end time is excluded.

time_bars_build_delay: u64

The time delay (microseconds) before building and emitting a bar.

time_bars_origins: HashMap<BarAggregation, Duration>

A dictionary mapping time bar aggregations to their origin time offsets.

validate_data_sequence: bool

If data objects timestamp sequencing will be validated and handled.

buffer_deltas: bool

If order book deltas should be buffered until the F_LAST flag is set for a delta.

emit_quotes_from_book: bool

If quotes should be emitted on order book updates.

emit_quotes_from_book_depths: bool

If quotes should be emitted on order book depth updates.

external_clients: Option<Vec<ClientId>>

The client IDs declared for external stream processing. The data engine will not attempt to send data commands to these client IDs.

debug: bool

If debug mode is active (will provide extra debug logging).
