What’s new in v2.3 (August 2026)

This release is mostly repair work: several indicators were quietly computing something other than what they described, one of them since v2.0. Everything new below is optional and off by default.

Two things after updating:

  1. Remove the old version first. NinjaTrader will not import over an already installed assembly (see Updating to a new version below). Your license and chart settings are preserved.
  2. KaizenBigTrades: set Aggregation Window (ms) back to 5. The parameter now measures something different (the gap between the fills of one sweep, not between ticks at the same price). A value carried over from an old template — usually 30 — merges separate orders into one bubble and overstates volume by roughly 13%.

Fixed

  • KaizenAlertLine finds your lines again (broken since v2.0): the indicator never detected a single horizontal line since v2.0. Detection no longer depends on the failing type check and now also finds lines in sub-panels and lines attached via Attach to → All charts.
  • Opening type (AMT) on 24-hour charts (values change): the OAR/OAV/OIV/OBV/OBR class is now taken from one shared source anchored to the 09:30–16:00 ET RTH session, independent of the chart’s trading hours. KaizenTPO, KaizenStatsProfile and KaizenVolumeProfile now agree. The label appears from 09:30 ET.
  • CustomTime windows were off by one bar at each end (profiles shift): the window is now evaluated as (start, end]. Affects KaizenVolumeProfile, KaizenTPO and KaizenDeltaProfile, so POC and value area shift slightly.
  • KaizenStatsProfile used an RTH open that was too early (probabilities change): the session boundary used the bar stamped 09:30, which still contains premarket. Some opening types and their conditioned probabilities differ from v2.2; the new values are the correct ones.
  • KaizenBigTrades was missing the largest orders (more bubbles): a sweep across several price levels is now stitched into one aggregate instead of breaking into pieces below the minimum volume.
  • Divergence lines in KaizenCVD and KaizenDeltaCandle detached from their pivots when scrolling back through history; KaizenCVD also drew a false divergence across the session reset. Both fixed.
  • Bar index in the bot API (for developers): indicators hosted inside a strategy calculating on bar close returned bar data off by one index. Review any rules built on those values.

New

  • KaizenVolumeProfile — low volume nodes (LVN), opening type (AMT class) above the profile, and a weekly profile from the session open (Week Starts).
  • KaizenFootprint — delta and volume side by side (DeltaAndVolume display mode).
  • KaizenTPO — Draw In Front Of Bars.
  • KaizenAnchoredVolumeProfile — mirrored delta histogram.

Requirements

  • NinjaTrader 8 (tested on 8.1 and above).
  • Tick Replay enabled for accurate historical data in all order flow indicators (Footprint, CVD, DeltaCandle, BigTrades, StackedImbalance, ClusterSearch, VolumeProfile in Tick mode, Speed of Tape). Without Tick Replay, history is computed from minute data only and loses accuracy.
  • Your license key in the format KAIZEN-XXXXX-XXXXX-XXXXX-XXXXX (it arrives in your purchase email). It works on up to 2 computers and is shared across all Kaizen indicators.

Step-by-step installation

  1. Download the file from the link in your purchase email. Do not unzip it.
  2. Open NinjaTrader 8.
  3. Go to Tools → Import → NinjaScript Add-On… and select the downloaded .zip file.
  4. Confirm the import. NinjaTrader installs and compiles the indicators automatically.
  5. Add any Kaizen indicator to a chart (Indicators → Kaizen folder).
  6. In the indicator properties, under “0. License”, paste your license key.
  7. Done. The key is saved once and works for all Kaizen indicators.

You will see the entire catalog of indicators in the list. The ones your license includes are drawn normally; the others show the notice “Visit kaizen-daytrading.com/upgrade to unlock it.” — you can expand your license at any time.

Enable Tick Replay

For accurate historical data, enable Tick Replay on the chart’s data series:

  1. Right-click on the chart → Data Series…
  2. Set Tick Replay to On.
  3. Apply and reload the chart.

The license key is stored in %LOCALAPPDATA%\KaizenIndicators\license.key.

Does NinjaTrader flag it as unknown?

Because this is new software, Windows SmartScreen or an antivirus (for example Norton) may show an “unknown publisher” warning the first time. This is a common false positive with recent NinjaScript installers: choose “More info → Run anyway”. If your antivirus quarantines the file, restore it and add it to the exceptions. If in doubt, write to us at support@kaizen-daytrading.com.

Updating to a new version

  1. Control Center → Tools → Remove NinjaScript Assembly → KaizenIndicators → Remove.
  2. Restart NinjaTrader.
  3. Tools → Import → NinjaScript Add-On → select the new .zip.
  4. Restart NinjaTrader.

Your license is preserved (no need to re-enter the key) and your chart settings are kept; new options appear with their default values.

When upgrading to v2.3 specifically, reset KaizenBigTrades → Aggregation Window (ms) to 5 (see What’s new in v2.3 above).
