Get real time

[fx.practic]

Hello.

When I use DateTime.Now, I get PC time.

Can I get "real" world time (for example current qoutes server time)?

Depending on your data provider, the DateTime from Time[0] might be the server timestamp.

Thank You, Radical! It was real news for me!

But, in purpose to protect my scripts, I'd like to have possibility to determine current date using any provider.

[Radical]

I don't think that's possible, at least not directly through the Ninja API. You might contact your data provider to see if they have their own API that has this functionality, and then you could just get the time through that API right from your NinjaScript.

Well, and is there a way to determine the name of current connectivity provider from indicator code?

Your original question that was answered asked about Current Time. This response talks about Current Date. The date is the date. It is the same for every provider and the PC, unless your PC has the wrong date. Do I miss the import of the question?

Oh, I'm sorry. It was realy ambiguous.

I want to protect my indicators from unlimited usage.
Date (and time) on local PC can be changed manualy. So, I want to find way to check real date.

After Radical said, that "Depending on your data provider, the DateTime from Time[0] might be the server timestamp" I decide to check (if possible) broker's name to ban usage when connected to brokers which not give own time-stamp.

So, can any body tell how to check broker's name (when connected) or how to get real date?

Does anybody can help, please?

In that case, you need to be able to check the date and time from a NTP server. Here are some links that have code to do that. You are going to have to massage the code to use it in NT, but, hey, it is just C#.

Thank you!
I see, I get what to do nearest couple of weeks.
This looks like universal solution.

This seems to be a simpler, NT specific solution to the same problem. In fact, I think I am going to implement it myself. Just check the exchange time, and I will get the real time, even if the computer time has been turned back.

Somehow though, I wonder if this is even necessary. I seem to remember that the exchange does not send data if the local clock date is different from the exchange date. I will have to cross-check to be sure, though.

koganam, thanks a lot!

I made a little investigation. Results - on screenshot, indicator in attach.
I changed PC date and time and print it in all known ways. (My provider - AMP, they assign to ticks native time.)

Сonclusion: DateTime.Now == Bars.MarketData.Connection.Now == PC Time


There is once more way: to bound indicator to futures name:

if( Instrument.FullName != "CL 11-12" && Instrument.FullName != "ES 12-12" ) //get out

But this way is not very universal.

So it appears then that AMP/CQG provides the actual time stamp to its data, so that Time[0] is actually the correct time? Hm. Not sure that all providers do that. You may still need to check that NTP Server, for a universal solution.

8 providers support and 7 not support native Real-Time Timestamp.

So, I agree with You - It's better to check some SNTP servers.

Aaaaghh. Back to the drawing board it is then.
