Bar values represent the outputs of chart types|topic=Chart Types. For example:
Spread Bar: HLC3
Within formulas, bar values are formatted like this:
Bar parameters are also indicated. For example, (@,TFlowSimpleAggregation,1). These parameters can be changed.
Bar values also include three studies: Bar, CVB, and TFlow External Data.
Note about Current Values: Current values (such as CurrentBestAsk, CurrentBestBid, and CurrentTickVol) were designed especially for building trade systems. As input variables in trade systems, the current bar values recalculate on every tick within the trade system regardless of recalculation settings (Setup > Chart Preferences > Recalc). Regular bar values follow the recalculation mode setting.
Bar values have no special syntax highlighting.
Operators in formulas
Operators create relationships between formula components. You can type operators in a formula, or you can insert them using the Toolbox.
In Formula Builder syntax preferences, mathematical and relational operators, commas, and question marks are included in the Operator group. Logical and movement operators are in the Keyword group.
