NinjaTrader 8 Order Flow Indicators: Footprint vs Candle Signals

An order flow indicator for NinjaTrader 8 reads the bid/ask volume traded inside each bar and shows you who was aggressive: buyers lifting the offer or sellers hitting the bid. The tools split into two families: footprint charts that show every number, and candle-based indicators that mark the conclusions on your existing chart.

Most "best order flow indicator" lists ignore that split. They line up footprint tools against each other and call it a day. But the first real decision is not which tool. It is which approach matches the way you actually trade. This guide covers both, with honest pricing and a clear note on where each one falls short.

What order flow actually measures

A standard candle shows open, high, low, and close. It hides what happened inside the bar. Order flow tools open the bar up and separate volume by aggressor:

• Ask volume: buyers crossing the spread to hit the offer
• Bid volume: sellers crossing the spread to hit the bid
• Delta: the net difference between the two

From that raw split you can spot absorption (heavy aggression that fails to move price), trapped traders (aggressive orders left on the wrong side of a reversal), and imbalances (one side stacking far above the other at consecutive prices). Every order flow indicator below is built on this same tick-level data. They just present it differently.

The two families

1. Footprint charts: show every number

A footprint (or volumetric) chart replaces each candle with a grid of bid x ask volume at every price level. You see the complete picture: which prices traded, how lopsided each level was, where the point of control sat. Nothing is hidden.

The tradeoff is reading load. A footprint is a wall of numbers. In a fast NQ session you are scanning a dense grid while price moves. For traders who have put in the screen time, that detail is the edge. For everyone else, it is information overload.

2. Candle-based signal indicators: mark the conclusions

The second family runs the same tick math but does not draw the grid. Instead it marks the outcomes on your normal candlestick chart: a colored bar where absorption happened, a zone where imbalances stacked, a marker where traders got trapped. You read your chart the way you already do, with the order flow events highlighted.

The tradeoff is the reverse: you trust the indicator's logic instead of reading every cell yourself. You get speed and clarity, but less raw detail.

Neither family is "better." They serve different traders.

Native option: NinjaTrader Order Flow+

NinjaTrader ships its own order flow suite, Order Flow+, which includes volumetric (footprint) bars, volume profile, a native cumulative delta study, and a few other tools.

• Price: Included at no extra cost with a funded NinjaTrader brokerage account or a NinjaTrader Lifetime license. Without a funded account, it is a $59/month standalone add-on. (Source: NinjaTrader support documentation.)
• Best for: Traders who already fund a NinjaTrader account and want native footprint detail with no third-party install.
• Limitation: It gives you the raw tools, not pattern detection. There is no automated trapped-trader, absorption, or confluence logic. You read the footprint and draw your own conclusions. For automated delta divergence, Cumulative Delta PRO is the WickLabs alternative.

If you have a funded account, start here before paying for anything. It is the honest baseline every other tool is measured against.

Third-party footprint suites

If you want a deeper footprint than the native tool, two are worth knowing:

• TradeDevils (TDU) Footprint: A feature-heavy footprint with 25+ imbalance detection modules, alerts, and 101 NinjaScript plots. $55/month or $459 lifetime, with a 7-day trial. (Source: TradeDevils product page.)
• MZpack: Tick-based footprint, heatmaps, and auto-generated S/R zones. MZpack also gives away a free tier (mzFootprint, mzVolumeProfile, mzBigTrade) with a paid full version. (Source: MZpack site.)

There are also genuinely free footprint indicators, such as Praveen Orderflow, that cover bid x ask clusters, value area, and stacked imbalances at no cost. If budget is the only constraint and you are willing to read a grid, a free footprint is a real option.

Candle-based option: WickFlow PRO

WickFlow PRO is our order flow indicator for NinjaTrader 8, and it sits squarely in the second family. It processes tick-by-tick bid/ask data and marks the events on your candles instead of drawing a footprint grid.

It runs seven order flow signals plus a confluence system (marketed as eight engines):

• Trapped Traders: aggressor-side concentration zones, separating who was aggressive rather than just where volume sat
• Absorption: single-bar and multi-bar clustering, with zones that project forward as support/resistance
• Stacked Imbalances: diagonal ladder scanning that walks the full per-tick price ladder
• Surge: dual-path momentum detection (magnitude and intensity) with a late-bar speed confirmation
• Delta Participation: swing-to-swing cumulative delta comparison for exhaustion and continuation
• Delta Flip: a two-bar opposing-divergence reversal pattern
• Unfinished Business: failed-auction levels tracked until price retests them
• Confluence System: highlights bars where multiple signals agree in the same direction

A few specifics that matter:

• No footprint grid required. Signals print on standard candles
• Runs on raw Level 1 bid/ask tick data. You do not need the Order Flow+ add-on for WickFlow to calculate aggression
• Tick Replay is required for accurate historical signals (this is a real requirement, not optional)
• Deterministic. Once a bar closes and a signal qualifies, the mark is permanent. It does not repaint.
• Best on Range, Tick, or Volume charts. Time charts are not recommended, because the engines read intra-bar speed and sequence
• Strategy Builder ready. 21 signal outputs export as public NinjaScript series
• Price: $259.99 lifetime, with a 7-day full-feature trial and no credit card required

The Stats Calibration Lab is the part traders tend to remember. It compares your current thresholds against recent completed bars and labels each engine as loose, calibrated, selective, or unreachable, so you tune to your instrument instead of copying a stranger's settings. The full walkthrough is in How to Calibrate WickFlow Engines.

Which should you choose?

• You already fund a NinjaTrader account and want footprint detail: Use Order Flow+ first. It is already paid for.
• You want the deepest possible footprint and read grids fluently: A dedicated footprint suite like TradeDevils or MZpack will out-detail the native tool.
• You are on a strict budget: A free footprint (MZpack's free tier, Praveen) gets you real order flow with no spend.
• You want order flow conclusions on your candles without reading a grid: That is exactly what WickFlow is built for.
• Delta and divergence are your main workflow: Cumulative Delta PRO is the focused WickLabs tool for that job.

When WickFlow is the wrong tool

Honest version, because it matters: if your edge comes from reading the raw footprint cell by cell, or you need a DOM heatmap or iceberg reconstruction, WickFlow is not what you want. It deliberately hides the grid. It also needs Tick Replay and works best on Range, Tick, or Volume charts, so a pure Time-chart trader will not get the most from it. Pick the family that fits your style first, then pick the tool.

Frequently asked questions

What is the best order flow indicator for NinjaTrader 8?

There is no single best one. If you want a native footprint baseline and already fund a NinjaTrader account, Order Flow+ is included. If you want maximum footprint detail, TradeDevils or MZpack go deeper. If you want order flow signals marked on standard candles instead of a footprint grid, WickFlow PRO is built for that approach. For automated delta divergence, use Cumulative Delta PRO.

Do I need NinjaTrader Order Flow+ to use a third-party order flow indicator?

Not always. WickFlow calculates aggression directly from raw Level 1 bid/ask tick data, so it does not require the Order Flow+ add-on. Footprint tools vary, so check each vendor's data requirements.

Can I get order flow on NinjaTrader 8 without footprint charts?

Yes. Candle-based indicators like WickFlow run the same tick-level bid/ask math but mark the results (absorption, trapped traders, imbalances, surges) on your normal candlestick chart instead of drawing a footprint grid.

Is there a free order flow indicator for NinjaTrader 8?

Yes. MZpack offers a free tier, Praveen Orderflow is free, and the NinjaTrader Ecosystem hosts community tools. We also publish a free Big Trades indicator that detects large prints and sustained aggression with no time limit.

Does WickFlow repaint?

No. WickFlow is deterministic. Once a bar closes and a signal meets its criteria, the marker, zone, or confluence highlight is permanent.
