Free NinjaTrader 8 Indicator

The tape’s pulse, inside the killzone.

Trades per second. Volume per second. The buy-vs-sell aggressor ratio. Tick Velocity puts the pace of the tape on the chart as a floating HUD, 1-second for scalping the auction, 5-second for steady tape reading, 30-second for catching regime shifts inside the macro. Three corners, three windows, every metric toggleable. Reads the tape without the separate Time & Sales window.

TICK VELOCITY

Read the tape without reading the tape.

A clean HUD that decodes raw tick activity into three numbers you can act on. When trades/sec spikes and the aggressor ratio tilts hard to one side, you've got an institutional pulse before the bar even closes. When velocity collapses into a key level, you've got absorption forming. The numbers tell you what the chart is about to confirm.
Tick Velocity HUD on a NinjaTrader 8 chart. TRADES/S 69.0, VOL/S 79.2, and a B/S ratio divergence bar in the top-left corner
Tick Velocity HUD anchored in the top-left corner, 69.0 trades/sec, 79.2 contracts/sec, with the buy/sell aggressor ratio shown as a divergence bar below.
Three live metrics
TRADES/S
Trades per second
Count of executed trades over your selected window. The raw pace of the tape. Spikes flag when institutional activity is firing through the book, calm periods flag low-conviction drift.
VOL/S
Volume per second
Aggregate contract volume over your selected window. Decouples velocity from size. High trades/sec with low vol/sec is small-order chop, low trades/sec with high vol/sec is large-size accumulation.
B/S RATIO
Aggressor ratio bar
Buy aggressors versus sell aggressors classified live from the tape (price at ask = buy, price at bid = sell, mid-prints neutral). Rendered as a divergence bar so you can read the imbalance at a glance.
Three windows, three corners
1s / 5s / 30s rolling windows

Switch the aggregation window with one click on the chart toolbar. 1s for scalping the auction, 5s for steady tape reading, 30s for catching slower regime shifts.

Top-left / Top-right / Bottom-right

Pin the HUD wherever it stays out of the way. The corner toggle on the pill lets you move it without opening settings. Useful when a moving setup needs the corner the HUD was sitting in.

Per-metric toggles

Show or hide Trades, Volume, and Ratio independently. Run a minimalist single-metric HUD or the full three-row read. Live-toggleable, no restart.

Real-time only. The HUD intentionally hides during historical bar load. The metrics are tape-tempo readings, not chart annotations, and showing stale historical values would be misleading. The moment NT8 hits Realtime state, the HUD appears.
FEATURES

Built for tape readers

Aggressor classification on every tick

Every trade is classified as buy, sell, or neutral the moment it prints. Buys hit the ask, sells hit the bid, mid-prints are counted in trades but excluded from the ratio. Pure Level 1 tape. No Order Flow+ subscription needed.

Tick-time aware aggregation

Bucketing is keyed on the exchange tick timestamp, not your PC's clock. The HUD reads correctly whether NinjaTrader is set to ET, CT, UTC, or any other timezone. The second boundaries always align with the exchange's tape.

Toolbar pill controls

Window (1s/5s/30s), corner (TL/TR/BR), and per-metric toggles (T/V/R) all live on a "TAPE" pill on the chart toolbar. No dialog, no restart. Settings gear opens the rest.

SharpDX-rendered HUD

Direct2D rendering with cached brushes. Zero flicker, zero allocation per tick. The HUD updates as fast as the chart refreshes without dropping a frame on a moving tape.

Keeps accumulating off-tab

Stays active when the chart tab is hidden. Switch to another tab, come back, and the velocity read picks up exactly where you left it. Consistent with how CVD and VWAP behave during workspace navigation.

Stackable with the suite

The "TAPE" pill participates in the unified FlowForged toolbar system. Master Switch toggle, draggable reorder, keyboard shortcut. Stack it alongside Hammer and Volume Profile for a complete tape-reading setup.
