Bar Field
Extracts one scalar value from a connected bar.
Extracts one scalar value from a connected bar.
When to use
Use it when a consumer needs Open, High, Low, Close, Volume, or another available bar field instead of the complete bar.
Example
Extract Close from the latest bar and compare it in Condition.
Extract one value
Connect a Bar payload from a bar-close event to Bar Field: Bar and choose Close. For an illustrative completed bar with Open 100, High 112, Low 98, Close 108, the active Close output is a price value of 108. Connect that value to a compatible numeric or price input such as a comparison. Choosing Volume instead exposes a number with different meaning; do not compare volume to a price threshold without explicitly changing the rule. The extractor reads the supplied bar and does not fetch a later bar or trigger control execution.
Common problems
Connect a bar value, not a collection of bars. Recheck the selected field after changing the upstream event or data source.
