Big Trades PRO
Orderflow indicator for NinjaTrader 8.

Big Trades PRO includes four detection engines: Impulse Run, Price Node, Single Print, and Market Aggression. It also features Big Trades Zones for tracking historical absorption and exhaustion, full NinjaTrader strategy automation outputs, and three aggressor detection methods.

Single Print mode identifies individual block trades executed in one immediate event. Market Aggression aggregates smaller trades hitting the bid or ask over a short time window at a single price. This helps reveal large iceberg orders absorbing retail flow.

Impulse Run looks for short-lived directional bursts, then checks whether they were actually clean enough to matter. It first requires at least one aggressive trade to execute at the current best bid/ask, plus minimum traveled range, then uses three quality gates: counter-volume ratio (did the other side fight back too much?), one-wayness (did price get there cleanly or through chop?), and front-load urgency (did the directional volume hit early, or only build late?). The goal is to avoid marking every random sweep and instead surface cleaner participation events you can combine with structure and levels.

Use the Price Node engine. It identifies the single dominant price level within a completed bar, effectively a micro Point of Control for that bar. Price Node then filters that level by absolute size and node dominance, so you are not just plotting every random bar POC. With Zones enabled, those accepted levels become clean intraday support/resistance references.

When a bubble forms, Big Trades Zones projects a horizontal zone forward as a support/resistance reference area. You can enable or disable zones, control Zone Padding for SinglePrint and PriceNode signals, choose how long zones extend with Zone Max Bars, and decide whether extension stops immediately once a zone is consumed. In MarketAggression and ImpulseRun, the zone uses the event's natural high/low range. Consumption is evaluated on completed bars: HighLowTouch uses wick overlap, BodyEnter uses real candle body overlap, and FullCrossThrough is directional close-through (buy zones require close below zone bottom, sell zones require close above zone top). Buy and sell zone colors plus opacity are configurable as well.

No. Big Trades PRO calculates aggression and block trades directly from raw tick data. You do not need the extra Orderflow+ add-on to visualize these orderflow events.

To reconstruct historical 'Big Trades' bubbles accurately on chart reload, NinjaTrader needs to 'replay' individual ticks. Without Tick Replay, NinjaTrader only provides OHLC data, hiding the intra-bar bid/ask intent required for detection.

Yes! Big Trades PRO exposes full public properties for all its modes, enabling you to build automated strategies catching momentum ignition and spoofing directly in NinjaTrader's Strategy Builder or via C# scripts.

Free Big Trades stays on Bid/Ask only. That method compares the execution price to the inside quote and is the most direct classification when quote data is fresh. PRO adds Up/Down Tick, which classifies from trade-to-trade price direction, plus Adaptive, which keeps using Bid/Ask while quotes are fresh and automatically falls back to Up/Down Tick when the last quote update is older than your stale-threshold setting.

No. Big Trades PRO does not repaint. Once an orderflow event meets your engine criteria and the bar closes, the bubble and its zone stay on the chart permanently.

Yes. You have complete control over the mathematical scaling. You define the Minimum Volume Threshold to trigger an event, and control the visual bounds via Orb Min Size and Orb Max Size settings.

Price Node is selective. It always resolves the winning node of the completed bar, but it still requires that node to pass both Min Volume Threshold and Min Node Dominance. That means the level must be large enough in raw size and concentrated enough relative to the rest of the bar. The result is a cleaner acceptance map rather than a noisy POC marker on every candle.

Yes. Big Trades PRO includes optional sound alerts under the Alerts settings group. Enable Sound Alerts, pick a WAV from the dropdown (it scans NinjaTrader's sounds folder), and optionally filter by side, minimum market volume, or cooldown. Alerts fire in realtime only and are PRO-only; the free indicator does not include them.

No. Big Trades PRO is a one-time purchase with a lifetime license. There are no recurring fees.

Your license allows for up to 2 simultaneous machine activations. You can deactivate an old machine to activate a new one via the dashboard.
