How to install NinjaTrader 8 indicators
Seven steps, about two minutes. The one people get wrong is step 3, so it has its own warning.
You need the platform itself before step 1 — a Precision indicator is an add-on that runs inside it, not a program of its own. The download is free and a simulated account costs nothing, which is enough to install this, drag it onto a chart and click around before any real money is involved.

- Download your Precision indicator ZIP and keep the file zipped.
- In the NinjaTrader 8 Control Center, choose Tools → Import → NinjaScript Add-On.
- Select the downloaded ZIP. Do not select an extracted folder.
- After the import completes, restart NinjaTrader.
- Right-click a chart, choose Indicators, and add your Precision indicator. Read the Machine ID displayed by the indicator.
- Use My Account to activate your paid indicator with that Machine ID. For the free Candle Countdown, use its claim form.
- Open the indicator settings, paste the key in 0. License, and click OK. Review the setup in simulation before live use.
Installing Signal Engine or News Notifier? The ZIP import process is the same; each tool has its own license and settings.
If it still will not appear
The indicator is not in my list after importing
Restart NinjaTrader — the list only refreshes on restart. If it is still missing, the import probably failed silently because the zip was unzipped first. Re-download and import the zip untouched.
I get a compile error when importing
That is almost always another add-on on your PC that already had errors — NinjaTrader refuses to import anything while any custom script is broken. Open New, NinjaScript Editor, press F5, and the error list names the file at fault. Fix or remove that one and the import will go through.
The indicator says UNLICENSED on my chart
There is no valid key in its settings. The Machine ID it needs is printed right there on the chart — copy it, activate at My Account, and paste the key into 0. License.
It says my key is not valid for this machine
The key was minted for a different Machine ID. Usually the ID changed, or the key came from another PC. Re-activate in My Account with the ID the indicator is printing right now and you get a fresh key free.
