Flow Gauges for Sierra Chart

Floating arc gauges that turn volume, delta, CVD, and tape speed into a single visual read. Each gauge runs as its own study, floats over any Chart or DOM, embeds/floats with a double-click, and is freely resizable.

Note: The same gauges will be available with configurable data source inputs in a separate bundle.

No credit card required.

Volume Flow

Total volume per bar on a single gauge. Same data as Sierra Chart’s built-in Volume study. Auto-color gradient shifts from low to high as the gauge fills.

Bid Volume Flow

Bid-side volume on its own gauge. Same data as Sierra Chart’s built-in Bid Volume study. Pair with Ask Volume Flow for a side-by-side read.

Ask Volume Flow

Ask-side volume on its own gauge. Same data as Sierra Chart’s built-in Ask Volume study. Pair with Bid Volume Flow for a side-by-side read.

Bid vs Ask Volume Flow

Dual gauge with Bid Volume on one side and Ask Volume on the other. Optional gap value shows delta, total, or percentage.

CVD Volume Flow

Cumulative delta on a bidirectional gauge. Same calculation as Sierra Chart’s built-in Cumulative Delta Bars – Volume study. Positive fills one direction, negative fills the other.

Delta Flow

Per-bar delta (ask minus bid) on a bidirectional gauge. No cumulative tracking, just the raw delta for each bar.

Tape Flow

Measures tape speed from raw Time and Sales data. Count trade prints or sum volume over a configurable rolling window.

Key Features

Float or Embed – Each gauge runs in its own floating window. Double-click to embed directly on the Chart Region, Scale Region or DOM Column. Right-click for the context menu while floating.
Resize – Drag the window edge to make a gauge larger or smaller. Text and arc thickness scale proportionally.
Auto Range – The gauge max automatically ratchets up to the highest value seen during the session. The peak never decreases on its own. Right-click the Gauge submenu and select Reset Auto Range to recalibrate after a spike.
Threshold Markers – Place a tick mark at a specific value on the arc. Bidirectional gauges mirror the threshold as +/- automatically.
Auto Markers – Evenly spaced division marks across the arc for visual reference. Set 1 to 5 markers, or disable with 0. Markers adjust automatically with the current max value.
Anti-Aliased Rendering – Floating mode uses smooth arc rendering. Embedded mode uses Sierra Chart’s native GDI, which may show minor arc artifacts at smaller sizes. Disable anti-aliasing on the Gauge tab to match rendering between modes.

Auto Color Gradient – Unidirectional gauges can color the arc through a low, mid, and high gradient based on fill percentage. Bidirectional gauges use positive, negative, and zero colors.
Subgraph Output – Every gauge outputs its current value as a subgraph, matching the output of Sierra Chart’s built-in study of the same name. Use it for spreadsheet logging, alert conditions, or as input to other studies. Tape Flow also outputs its peak value.
Settings Window – All configuration is managed through a tabbed settings window with Gauge, Display, and Data tabs. Right-click the chart and select Open Settings, or use the context menu on the floating window.
Presets – Save, load, and share named configuration presets. Each gauge type stores presets in its own file. Export a preset to share it and import to restore settings.
Right-Click Quick Toggles – Toggle Auto Range, Flip Vertical, Auto Color, Show Label, Show Value, and more from the Gauge submenu without opening the settings window.
Theme Support – The settings window supports dark and light themes to match your Sierra Chart color scheme.

The Gauges

Each gauge is a standalone study. Add any combination to a chart or DOM. All seven share the same floating window framework, settings window, and configuration options. The difference is what data they display and how the arc behaves.

Unidirectional gauges (Volume, Bid Volume, Ask Volume, Tape) show a single positive value. The arc fills from zero to the current value, with an optional gradient that shifts color as the gauge fills. These are best for tracking magnitude.

Bidirectional gauges (CVD, Delta) show positive and negative values. The arc fills in one direction for positive, the other for negative. Separate colors for each direction make it easy to read the sign at a glance. These are best for tracking net direction.

Dual gauges (Bid vs Ask) show two values on a single gauge, one arc on each side. The gap between the arcs can display delta, total, or percentage. This is the only gauge that shows two independent values simultaneously.

Setup

Each gauge is a separate study in the gcUserStudies_FlowGauges DLL. Add the ones you want from Analysis > Studies.

Add a Gauge – Open Analysis > Studies, search for “gc:” and look for the Flow Gauge studies. Add one to your Chart or DOM.
Position It – The gauge appears as a floating window. Drag it where you want it. Double-click to embed on the chart. Double-click again to float.
Configure – Right-click the floating gauge and select Settings, or right-click the chart and select the study’s Open Settings menu item. All options are in the tabbed settings window.

What is the difference between the gauges?

Volume, Bid Volume, and Ask Volume are unidirectional arcs showing a single positive value per bar. CVD and Delta are bidirectional arcs showing positive and negative values. Bid vs Ask is a dual arc with both sides visible and an optional gap value. Tape Flow processes raw Time and Sales data to measure trade activity rate over a rolling time window.

Can I run multiple gauges on the same chart?

Yes. Each gauge is its own study. Add as many as you need to the same Chart or DOM. Each instance runs independently with its own settings, position, and size.

Can I use my own data source from other studies?

That will be released in a separate bundle within the next week. Flow Gauges was designed to be simple and self contained. Each gauge reads its own data with no setup required. The same gauges will be available with configurable data source inputs.

How do I switch between floating and embedded?

Double-click the gauge to embed it on the chart. Double-click again to float. You can also right-click the chart and select the study’s Float menu item. The context menu with display settings is only available while floating.

Can I resize a gauge while it is embedded?

Not directly. Embedded gauges use the size they had when embedded. To resize, double-click to float, resize the window, then double-click to re-embed at the new size.

How does Auto Range work?

When enabled, the gauge max automatically increases to match the highest value seen. It never decreases on its own. To recalibrate after a large spike, right-click the gauge, open the Gauge submenu, and select Reset Auto Range. You can also set a fixed max value by disabling Auto Range in the settings window.

What happens to Auto Range when I close and reopen the chartbook?

Auto Range peak is runtime-only and resets when the chartbook is closed or the study is removed. The gauge rebuilds its peak from live data after reopening. Your visual settings (colors, thresholds, label) are saved with the chartbook.

What does the Tape Flow gauge measure?

Tape Flow reads the Time and Sales feed directly and counts trade activity over a configurable time window. In Ticks mode it counts individual trade prints. In Volume mode it sums the lots traded. The interval (in seconds) controls how wide the rolling window is.

Does the Tape Flow gauge work during replay?

Yes, it processes replayed T&S records. After a Reload and Recalculate (Insert key), the gauge briefly reprocesses the T&S buffer before resuming. This is normal.

Can I use these on a regular Chart or DOM?

Yes. The gauges work on both chart windows and DOMs. Each gauge uses the same underlying data as Sierra Chart’s built-in studies of the same name (Volume, Bid Volume, Ask Volume, Cumulative Delta Bars). The Tape Flow gauge reads from the Time and Sales feed, which is available on any chart receiving live or replayed data.

Will the gauge follow the Sierra Chart window when I move it?

Floating gauges are anchored to the chart they were added to but do not currently follow when you move the main Sierra Chart window. If the gauge appears to drift or sit in the wrong position after moving the window, right-click the gauge and select a position preset, or drag it back into place. Improved window tracking is planned for a future update.

What happens when I attach or detach a chart?

The gauge detects chart attach/detach transitions automatically. In some cases the floating window may briefly reposition. If the gauge does not appear after an attach/detach, check the SC right-click menu for the study’s Float menu item to bring it back. The gauge location can also become out of sync when floating on detach depending on where the detached chart position ends up. To solve this completely, you can embed the gauge to the chart.

Can I access settings while the gauge is embedded?

The right-click context menu is only available while floating. To open settings from embedded mode, right-click the Chart or DOM Region and select the study’s Open Settings menu item. You can also set the “Open Config Window” input to Yes in Study Settings.

How do I choose which symbol the gauges display?

Each gauge uses the symbol of the chart it is added to. To monitor a different symbol, add the gauge to a chart configured for that symbol. A future update will explore the ability to target a user-specified symbol from any chart, allowing multiple gauges for different instruments on a single chart.

What Sierra Chart version is required?

The gauges are built for Sierra Chart version 2784 and above.

v1.0.0 Changelog:

Initial release with seven gauges: Volume Flow, Bid Volume Flow, Ask Volume Flow, Bid vs Ask Volume Flow, CVD Volume Flow, Delta Flow, Tape Flow
