RE: Update to net8.0
firemyst said:
Definitely!
It should be a relatively easy transition/update since they already have version 6 supported.
Net6.0 is officially out of support as of 12th November 2024. Which implies CTrader.Automate 1.0.9 is now not production worthy.

RE: CAlgo objects failing to serialize via ToJson
EDG777 said:
I think the error is due to the presence of curly braces that the formatting system interprets as placeholders. To fix it, escape your braces or ensure the string passed to the logging/printing function doesn’t contain unintended formatting tokens.
Maybe it will help:var jsonString = Account.ToJSON();jsonString = jsonString.Replace("{", "{{").Replace("}", "}}");Print("[OnStart] Account:\n" + jsonString);
Thank you for the tip. It worked fine for the serialising case. But l am finding deserializing the resulting json string back to the object errors with the following:-
15/12/2024 08:35:50.035 | Info | [OnStart] {JsonReaderException} Exception : Invalid property identifier character: {. Path '', line 1, position 1.
This error occurs for both Newtonsoft.json and system.text.json

I have reverted to CTrader version 4.8(909) and the cbot is working fine on there. I think there is a bug in version 5.0. I need version 5.0 because it is the only version on MacOS with backtesting capability. I would be eternally grateful if you could you sort it out please.
I have reinstalled Ctrader for mac version 5.0.22 and ran the cbot under backtesting and the error has emerged. See screenshot attached. There id a comms bug in Version 5.0.

Check this thread below
The Klein sample does not work properly, use the console sample and adapt it to your code. You also need a broker to authorize your CTrader account to access the OpenAPI platform. If you are in the UK, you would have your work cut out finding such a broker. Having a CTrader account for desktop or Mobile Apps do not automatically grant you access to the OpenAPI service l have found. Contact your broker to negotiate access.

RESOLVED
The solution was to define the redirect urls correctly. Your redirect should be set to http://localhost:5035/redirect for example. Or https://{your domain url}:[your preferred port}/redirect. Also bear in mind that the OpenAPI Client requires two loops of authentication to get going. You application have to authenticate via Oauth, thereafter, the application also need to authenticate the Account you wish to use for trading. The OAuth authentication requires you to log into the OpenAPI platform and authorize your application to access the platform. This act issues an Authcode to your application which it uses to obtain an Access Token to complete the authentication. From here on, the fun begins.
Thank you for your help PanagiotisChar.

RE:
PanagiotisChar said:
Hi there,
The samples definitely work, probably you are doing something wrong in the process. Try asking in the samples GitHub repository too, maybe you will get some help by Python users.
I have retried the Klein sample and it does not work. The basic example on the Python SDK page connects successfuly with my credentials. But it does not carry out a OAuth authentication that
should provide an Authcode. The Console sample successfully conducted a basic OAuth authentication but failed due to redirect URL.
The default redirect URL for the application is as shown below. The authentication process only works when l use the "https://openapi.ctrader.com/apps/4012/playground" redirect URL which fails to provide an Authcode. I have added the second redirect URL which unfortunately produces the error in the image above. Any other permutation of the redirect URL produces the errors that l previously mentioned in my previous posts. I am guessing that this is the case because l do not have a live account yet.

Hi there,
I am not familiar with Python, sorry :(
Has anyone ever connected to the CTrader Open Api successfully using Python or the samples offered on the Applications website, l wonder? I am hopeful that those samples has been tested and are fit for purpose. My expectation is that they should be able to establish a connection to the OpenApi platform.

Hi there,
I am using the python example based on Klein and Twister to verify the connection. The information provided is from the initial stages of the code as shown below:-
I have adapted this code to test the authentication and the result is what l posted previously. My code is based on the same principle but using flask and connextion. The result is the same. It is probable that the server version has moved on and the sample code is no longer valid. If that is the case, please can you advice me on what has changed?

Hi there,
The client ID you are using does not seem correct to me
This is the full URI:-
authUri: https://openapi.ctrader.com/apps/auth?client_id=4012_1kzEubcpMG4qFkGmyWjGxvL94iU5eJVSs9jz1xvGTlAbZuQxo3&redirect_uri=http://demo-eu.ctraderapi.com:5035/redirect&scope=trading
authcode: {'errorCode': 'ACCESS_DENIED', 'description': 'Access denied. Make sure the credentials are valid.'}
The account is active and the credentials is valid, l checked before putting up this post. There appears to be something wrong at the server end.

The issue might be with the credential which incidentally has a status of ACTIVE.

RE: RE: CAlgo objects failing to serialize via ToJson
ctid402288 said:
I finally got this to work. It turns out that the string from ToJSON is not a valid Json. To make it a valid json you also have to convert all double quotes in the string into single quotes as below:-
jsonString = jsonString.Replace("{", "{{").Replace("}", "}}").Replace("\"", "'");This would transform the string into a valid json which can be deserialized or sent over http. [Always a good etiquette to provide the solution so other can benefit from it]
