Tick Field
Extracts one scalar value from a quote or trade tick.
Extracts one scalar value from a quote or trade tick.
When to use
Use it when a comparison or calculation needs a price, size, or other available tick field.
Example
Extract an ask price from a quote tick and feed it to an Expression.
Match the payload type
For a quote-tick event, connect the Quote Tick payload and select a quote field such as Bid or Ask. An illustrative quote with Bid 100 and Ask 101 has a spread of 1 in the same price units. For a trade-tick event, connect Trade Tick and select Last or Size as appropriate. The selected source type controls which fields and input are meaningful; a trade payload does not provide a quote's Bid/Ask pair. Inspect the active port after changing source type, and keep the Event Trigger's tick event aligned with this extractor.
Common problems
Choose the correct source kind first. A quote-only field is not available for a trade tick, and a tick is not a bar.
