for context, 4.0.3.12 is what we currently use in production, we really would like to prevent such surprises in future.

Hi Jason,

Thanks, I need to test it, but I think it will work once I switch to 4.0.3.44.

However,

1. Is 4.0.3.12 still supported? I had no news on it, so this really came as a surprise
2. Assuming it is, then this issue should be fixed at the LIVE server, yes?
3. If it is not, where do I sign up for updates?

Thanks.

Hi,

My Gf.Api.Dll version 4.0.3.12 is throwing an exception when logging into LIVE.
The same binary does not throw any exception when logging into DEMO.
Object reference not set to an instance of an object
The issue started today 21st May 2021. Please advise.

Hi Evgeny,

My customer complained using a compiled binary. Now his issue is gone.
What I'm trying to say here is, the code is unchanged, so I don't see how it is the issue.

The binary searches for GGCH by default.

I tested by changing to GGC to try and understand what's going on. Now I understand it only returned GGCF because the code was asking for only 1 result.

Hi Evgeny,

Ok, it was my mistake, now it is working.

But just to re-iterate, yesterday when I search GGCH, it was not working. And when I search GGC, only GGCF was returned.

Anyway, thank you.

The API account always expires, please issue me 1 if you require me to test against the API.

1. You asked for my account, can you check the logs on your DEMO server please?
2. Let's not get into a you say, I say situation. My code works for ESH, YMH and so on.
3. If I search for GGC, only GGCF21 is returned.

Once again, PLEASE check the server logs.

Hi Evgeny,

Our application has cleared the API stage and is in production.

I just checked again, `e.Contracts.Count` is 0, not just for my DEMO account `LSeong64` but for other traders who reported the issue.

The code works for ESH and other symbols in DEMO and LIVE. Only GGCH is affected.

Hi,


_frontEsSymbolLookupRequestID = client.Contracts.Lookup.ByCriteria(New SymbolLookupRequestBuilder().WithResultCount(1).WithSymbol("GGCH", TextSearchMode.StartsWith).Build())


I get no symbols with the above code, GGCH21 ought to match, right?

Is there a way to determine if the trader has datafeed permission for his requested symbol?

Feedback » Account confusion May 18, 2020 @ 10:45 PM (Total replies: 2)

Hi,

I'm quite confused with my account logins at the following places:

1. https://apisupport.gainfutures.com - TLau471, password A
2. https://myaccount.gainfutures.com/Account/Login - TLau471, password B
3. API - TLau471, password B

I can change password B by logging into #2.
How do I change password for A?

API Support » Different behavior in API vs LIVE server May 18, 2020 @ 10:40 PM (Total replies: 4)

Hi,

I found a difference in behavior between the API and LIVE server:

1. API server, called Subscriptions.Ticks.Subscribe for 18th May 07:19:08 til 07:19:13, Subscriptions.Ticks.TicksReceived is triggered almost immediately
2. LIVE server, called Subscriptions.Ticks.Subscribe for 18th May 07:19:08 til 07:19:13, Subscriptions.Ticks.TicksReceived is not triggered

Please advise. Thank you.

Too fast? Sorry, but I don't think using sleep(10) is the robust approach to event driven programming.
I mean why 10? why not 1? or 100? It sounds more like a race condition. Can it be looked into?
I can't tell if the server is rejecting the connection or the API being unable to connect out..

Again, what I'm asking is B, what is the recommended way for API clients to perform re-connection.
Since client.Connection.Aggregate.Connect() is an asynchronous call, my first approach is to call it from inside the Disconnected event if the trader has specified to reconnect automatically.

Thank you.
