VendorLicense() issues

[snoussi]

Hello,
I have a question regarding the VendorLicense() variable, can it affect the outcome of a strategy?
Because I made exactly the same script, one without the variable and the other with the variable that I shared with clients, but I notice that we do not have the same entries at all, while the code is exactly the same.

thank you for your reply

You think that's the only possible difference that could
explain what you're seeing?

You want to know another thing that is different?

The data.

[bltdavid]

Differences in data are the more likely explanation.

When you and your client run the exact same script.
-- I mean the exact same DLL, same parameters,
same everything -- are you saying you both see
the exact same results? All the time?

Are they being run on the exact same chart or on different charts with the same settings?

Thank you for your feedback.
1. It's exactly the same chart and the same timeframe and for the same instruments
2. The settings are exactly the same for everyone
3. But from time to time the execution is not done at the same price.

I tested the 2 scripts at home, one without the variable and the other with the variable and I don't have the same entries, although everything is the same, so I was wondering if this variable had an impact or not and if yes, how to fix it

Hello snoussi,

Thanks for your notes.

It is not expected that the VendorLicense() section of the code would interfere with a NinjaScript strategy placing orders. The NinjaTrader Vendor License Management service is a user authentication feature that provides the following capabilities:

• User authentication using a unique ID generated from the PC machine ID* and a user defined ID.
• Create, update and manage user licenses through a GUI
• Create time based licenses
• Create free trial based licenses
• Process friendly and efficient authentication process that is approved by NinjaTrader
• Authentication for both indicators and strategies (NinjaScript objects)
• Authentication executed on NinjaTrader hosted primary and secondary (backup) servers
• License management information maintained on NinjaTrader hosted servers including backup

Typically, if you see a difference in the strategy placing trades between a client and yourself, it is likely that the data the script is being run on is different. This could be a difference in the chart interval (1-minute, 1000 Volume, 100-Tick, etc.), data provider, latency, etc.

You could consider testing the script using the Playback connection with Market Replay data to mimic the strategy running realtime. This would allow you to try to reproduce the behavior. Note the time the behavior occurs when testing in Playback. You could then further debug your strategy and settings to narrow in on the cause of the behavior and test your code at the the same point in Playback where you saw the behavior occur.

To ensure the data is the same between tests, you could consider downloading Market Replay data on one machine and copy the downloaded data to the second machine. Market Replay data is stored in the Documents\NinjaTrader 8\db/replay folder.
