Can not receive lightstreamer parices

[oolinaroo 0]

Hello!

We using package 

"lightstreamer-client": "~6.1.4" (legacy-server-5.1.2)

Successfully authenticated, subscribed and recive next events:

CLIENT onPropertyChange [|LightstreamerClient|1|5|2|]
SUBSCRIPTION onListenStart subscription=[|Subscription|5|0|1|1|2|]
CLIENT onStatusChange CONNECTING
CLIENT onStatusChange CONNECTED:STREAM-SENSING
CLIENT onPropertyChange serverSocketName
CLIENT onPropertyChange serverInstanceAddress
CLIENT onPropertyChange keepaliveMillis
CLIENT onStatusChange CONNECTED:HTTP-STREAMING
SUBSCRIPTION onSubscription
 

And never receiving event onItemUpdate:

For testing we using marketId:

{ Markets: [ { MarketId: 401449250, Name: 'EUR/USD', Weighting: 300 } ] }
 

Please help receive stream data.

Hi,

To help us troubleshoot:

• Please provide the code snippets you are using to perform the login and subscription to the price stream. 
• Which account operator are you with? Is it Forex.com or City Index?

Kind Regards, PM

Hi,

Thank you for the code snippet. Is your account with Forex.com or City Index?

Also, are you using a Demo/Test or Live (real money) account?

Kind Regards, PM

Account on  Forex.com

It is Live account

[Physicsman 25]

Thanks.

I'm sending you a forum private message with credentials to a Forex.com Demo/Test account that I know works fully with streaming price data. When you have a moment, please try using your code with the Test account and inform us of the result.

If it works 100% with your code, then we can probably look into investigating your Live account and eliminate a problem in your code. If you see the exact same fault as you do with your Live account, then it's likely the problem is in your code and your Live account is fine.

This quick trial will help us narrow down what we investigate further.

Kind Regards, PM

Thx!

Same situation...

this.subscription.setItems(["PRICE.401155666", "PRICE.401484347"]); 

/*

{ Markets:
   [ { MarketId: 401155666, Name: 'EUR/USD', Weighting: 958 },
     { MarketId: 401484347, Name: 'EUR/USD', Weighting: 300 } ] }
*/

Rates not stream. Firewall is off.

OK - we're making progress.

It looks as though the problem is somewhere in your code. We can look into that a bit deeper and see if we can spot anything. We'll reply again after we've looked it over. 

Kind Regards, PM

Thank you!

Waiting for feedback.

Hi,

According to the Lightstreamer documentation at https://lightstreamer.com/docs/client_javascript_uni_api/Subscription.html#setItems:

Quote

Any call to this method will override any "Item List" or "Item Group" previously specified.

 

It would appear in your code that this is redundant since your subscription call already specified an item list. Try commenting out the setItems code line and see if that helps.

Kind Regards, PM

Did not help.

[Physicsman 25]

Sadly, we've reached the limits of our expertise in Lightstreamer since this forum is for support on the REST API. 

Your last recourse is to try the Lightstreamer official forums at: https://forums.lightstreamer.com/ and see if they are able to troubleshoot your code. 

Kind Regards, PM

Also question:

When we pass presented fields in streaming data:

this.subscription = new this.ls.Subscription("MERGE",["item1","item2","item3","item4","item5"],["QuoteId","OrderId"]);
this.subscription.setDataAdapter("QUOTES");
We have same problems like in "PRICES" (no any data)

But if we add absent fields:

this.subscription = new this.ls.Subscription("MERGE",["item1","item2","item3","item4","item5"],["stock_name","last_price"]);

this.subscription.setDataAdapter("QUOTES");
We get:

{"py":2,"oy":"item2","hu":true,"ja":{"Xb":null,"xb":2,"list":["stock_name","last_price"],"Vs":{"stock_name":1,"last_price":2}},"Pd":[1,2,null,null]}
{"py":3,"oy":"item3","hu":true,"ja":{"Xb":null,"xb":2,"list":["stock_name","last_price"],"Vs":{"stock_name":1,"last_price":2}},"Pd":[1,3,null,null]}
{"py":1,"oy":"item1","hu":true,"ja":{"Xb":null,"xb":2,"list":["stock_name","last_price"],"Vs":{"stock_name":1,"last_price":2}},"Pd":[1,1,null,null]}
{"py":4,"oy":"item4","hu":true,"ja":{"Xb":null,"xb":2,"list":["stock_name","last_price"],"Vs":{"stock_name":1,"last_price":2}},"Pd":[1,4,null,null]}
{"py":5,"oy":"item5","hu":true,"ja":{"Xb":null,"xb":2,"list":["stock_name","last_price"],"Vs":{"stock_name":1,"last_price":2}},"Pd":[1,5,null,null]}

But event "onItemUpdate" is not coming.
