The most common questions when installing and using the Kaizen indicators in NinjaTrader 8. If your case is not here, write to us at support@kaizen-daytrading.com.
An indicator does not draw / shows “Visit kaizen-daytrading.com/upgrade to unlock it”
That notice means the indicator is not included in your license. The indicators your key covers are drawn normally; the rest show that message. You can expand your license at any time from kaizen-daytrading.com/upgrade. If you believe it should be included, check that you pasted the key in the “0. License” section of the indicator’s properties.
History looks wrong, empty, or “floating” (footprint, CVD, delta)
It is almost always Tick Replay. All order flow indicators (Footprint, CVD, DeltaCandle, BigTrades, StackedImbalance, ClusterSearch, VolumeProfile in Tick mode, Speed of Tape) need Tick Replay enabled to compute history with the correct bid/ask classification.
- Right-click on the chart → Data Series…
- Enable Tick Replay (On).
- Apply and reload the chart.
Note that your data provider must deliver historical ticks with bid/ask. Some feeds do not backfill them, and then the historical footprint loads blank even with Tick Replay enabled. See the data and brokers for NinjaTrader guide if the history is still empty.
It asks me to activate the license even though it is already valid
On some installations (especially with KaizenAnchoredVolumeProfile and KaizenAnchoredTPO) that message appeared despite having the correct license. It is resolved in the recent versions: update to the latest version (see below). The key is stored in %LOCALAPPDATA%\KaizenIndicators\license.key.
Windows or the antivirus flags the installer as “unknown”
Because it is new NinjaScript software, Windows SmartScreen or an antivirus (for example Norton) may show an “unknown publisher” warning the first time. It is a common false positive: choose “More info → Run anyway”. If the antivirus quarantines the file, restore it and add it to the exceptions.
The profile starts at the wrong time in CustomTime mode
It was an offset caused by the daylight-saving change (DST) between the Windows time zone and the chart time zone, which affected KaizenTPO, KaizenVolumeProfile and KaizenDeltaProfile. It is fixed in the current version (the conversion goes via UTC). If you see it, update to the latest version.
On how many computers does my license work?
The key KAIZEN-XXXXX-XXXXX-XXXXX-XXXXX is the same for all Kaizen indicators and works on up to 2 computers. You only enter it once.
How to update to a new version
- Control Center → Tools → Remove NinjaScript Assembly → KaizenIndicators → Remove.
- Restart NinjaTrader.
- Tools → Import → NinjaScript Add-On → select the new
.zip. - Restart NinjaTrader.
Your license and your chart settings are kept; new options appear with their default values. See also Installation and getting started.
