spotware / openapi.net Goto Github PK

Hi,

I've been testing out the API with python, but I'm having some trouble with getting the initial authorization working. Would it be ok if I share the code here, work on it and once it works, clean it up and put it up as a simple python examples repository for OpenAPI?

Thanks!

There is no longer a response when using GetTrendbars in the APIService.cs (WPF.Sample project). I have had no issues previously. Note that I can still get a trendbar response if I use the winforms sample.

Hey, I just want to inform you that the link on NuGet is wrong.
It goes to afhacker instead of this repo. 👍

Hi,

i have the latest npm package and get issue sometimes in Rx.NET/Source/src/System.Reactive/AnonymousSafeObserver.cs:line 65

How fix it?

Despite our best efforts, bugs can slip into releases or corner cases forgotten about. We will try our best to remedy the situation
and/or provide workarounds. Note that certain (odd) behaviors are by design and as such are not considered bugs.

Which library version? last release

What are the platform(s), environment(s) and related component version(s)? dotnet

What is the use case or problem? Stream get sometimes canced

What is the expected outcome? transfer data as complete

What is the actual outcome? Stream will be closed

What is the stacktrace of the exception(s) if any?

How can i fix it?

I've come across an issue with the library where calling ProtoOAAccountAuthReq does not return any response, no errors or anything, it just waits for a response indefinitely. (The initial request to ProtoOAApplicationAuthReq always succeeded.)

This issue doesn't happen all the time, I feel like it only occurs if there is a deployment ongoing on the Spotware side, I'm not sure. I've seen this happen several times in the past and usually fixes itself after a few hours.

I have figured out the cause of the issue, and it has something to do with the proxy URL returned by ApiInfo.GetInfo(Mode). The GetInfo() method returns "demo.ctraderapi.com" or "live.ctraderapi.com".

however, based on the Proxies/Endpoints documentation (https://help.ctrader.com/open-api/proxies-endpoints/), there are several region-specific servers that should be used, such as "demo-sg.ctraderapi.com" or "live-sg.ctraderapi.com".

Since I started using this library, the examples specify that the way to initialize the SpotwareClient object should be done like this:

OpenClient client = new(ApiInfo.GetHost(Mode.Demo), ApiInfo.Port, TimeSpan.FromSeconds(10));

Which would return the "demo.ctraderapi.com" or "live.ctraderapi.com" URL.

The fix is to not use ApiInfo at all during initialization of the OpenClient object, instead, either retrieve the region-specific URL from your database or hardcode the URL during ctor initialization.

I am currently using v1.4.4 of this library.

Maybe an update to the ApiInfo code should be done to support these region-specific API servers?

When going through the file samples/Console.Sample/Program.cs came across the following code at line 88:

System.Diagnostics.Process.Start("explorer.exe", $"\"{authUri}\"");

Since this is valid only on Windows, it can be wrapped in an if statement checking

System.OperatingSystem.IsWindows()

For the rest of the operating systems, the final authUri can be printed to the console or appropriate process can be opened (in MacOS it would be open command).

I can't create and a branch and create a pull request so the fix is here:
MessageFactory in GetMessage this line is missing

(int)ProtoOAPayloadType.ProtoOaDealListByPositionIdRes => ProtoOADealListByPositionIdRes.Parser.ParseFrom(payload),

Hi, I'm creating a Node.js framework for automatically operating in financial markets: https://github.com/Reiryoku-Technologies/Mida.

I understand that you are allowing this through the OpenAPI referenced at:
https://connect.spotware.com/docs/open_api_2

I have a question:

1. Am I allowed to integrate your API in my framework and allow users to login in their cTrader broker accounts to operate?

Thank you.

Had a problem with sending/receiving over TCP, but
I had just forgotten to use a SSL stream.

I'm unable to query PnL because this message does not exist in the dll
