FlexMeters is an RTX extension designed to enable Investor/RT users to display customized meters of market behavior within multi-pane charts. This flexible tool draws meters showing the present value of some price or computed value as compared to a specified range of values seen in the past. FlexMeters can be drawn using a variety of shapes, colors, dials, positions, titles, and labelling options. The underlying data values of a FlexMeter can be price values of the associated instrument, or values computed via an RTL custom indicator; thus there is unlimited flexibility in the kinds of market behavior gauges that can be available at a glance to the trader. The range or scale of the meter may be specified manually or it can be computed from minimum/maximum values of a recent period of trading. Even more flexibility can be achieved by specifing the range using C# or V# user variables that may be set by the user or computed by some RTL indicator elsewhere in the trader's workspace.
