Troubleshooting

Solutions to common issues with MZpack indicators for NinjaTrader 8.

Download Issues​

Download fails or shows an error after entering license key​

There are several possible causes:

  1. Typo or extra spaces in the license key — use copy/paste to enter the key instead of typing it manually.
  2. Wrong product selected — MZpack Indicators, MZpack Indicators w/ Divergence, and MZpack Single Indicators are different products. Make sure you select the one that matches your purchase.
  3. Expired subscription — check your subscription status at mzpack.pro under My Profile → Account → Orders.
  4. Not logged in — you must be logged in with the account used for purchase to see download links.

Installation Issues​

Indicators don't appear in NinjaTrader after installation​

Work through this checklist:

  1. Was NinjaTrader 8 closed during installation? If not, close and restart it.
  2. Open the Indicators dialog, type mz in the search box, and look under the MZpack/NT8 folder.
  3. If the indicators still don't appear, uninstall MZpack and reinstall.

See Installation — Verify for more details.

NinjaTrader shows errors on startup after update​

This usually happens when old and new versions conflict. To resolve:

  1. Close NinjaTrader 8
  2. Uninstall the old version via Settings → Apps → Installed apps (Windows 11) or Control Panel → Programs and Features (Windows 10)
  3. Install the new version with the latest installer
  4. Restart NinjaTrader 8

See Installation — Update for the standard update procedure.

License Issues​

Activation fails​

See Licensing — Activation Fails for the full checklist, which covers internet connectivity, firewall settings, retry steps, and contacting support.

Common license error messages​

See Licensing — Common License Errors for a table of error messages with causes and solutions.

License key not received after purchase​

License keys are sent within the next business day, usually within 3–5 hours.

  1. Check your spam, junk, and promotions folders.
  2. Some mail servers block messages from unknown senders — adjust your spam policy or provide an alternative email address (e.g., Gmail).
  3. If you still haven't received your key, contact support at mzpack.pro.

Data and Indicator Issues​

Footprint shows no data or all zeros​

Common causes:

  1. Tick Replay not enabled — MZpack processes historical data using NinjaTrader's Tick Replay feature. Enable it in your Data Series settings. See Order Flow — Data Levels for details.
  2. No tick data available — make sure your data feed provides Level 1 (tick) data for the instrument you're charting.
  3. Calculation mode mismatch — the default BidAsk mode requires bid/ask data in the tick stream. For instruments where this isn't available (e.g., Forex, crypto), use UpDownTick mode. For mixed scenarios, use Hybrid mode. See Indicators Overview — Calculation Modes for guidance.

Historical data looks different from real-time​

Without Tick Replay enabled, historical bars lack the tick-by-tick detail needed for accurate order flow reconstruction. Enable Tick Replay in your Data Series settings for consistent results between historical and real-time data.

Some features — such as iceberg detection and DOM pressure — require live data because NinjaTrader does not provide historical Level 2 data. These features will always show data only for bars built in real time.
