        Subject: Technical Issue: JSON Deserialization Error in Online Mode (2026)

        Message:
        Hi Algotrend team,

        I am writing to report a specific error with the "COT Institutional Sentiment Bot" on cTrader (purchased Jan 7, 2026). Since I cannot attach images here, I will provide the exact log details below.

        [My Environment]
        • Platform: The5ers Prop cTrader 5.5.13
        • Account Type: Live (Funded)
        • Symbol: EURUSD (h1)

        [The Error]
        When I set "Use COT History DLL" to "False" to fetch live data, the following error occurs in the log:
        TryFetchAndTrade error: System.Text.Json.JsonException: The JSON value could not be converted to System.Collections.Generic.List<cAlgo.Robots.CotApifySingleAssetBot+CotHistoryValue>.

        [Diagnostic Test Results]

        1. Online Mode (UseHistory=False): Fails with the JSON exception above.
        2. History Mode (UseHistory=True): Success. The log shows: COT: History loaded from DLL. Reports=40.

        [Conclusion]
        Since the core logic works fine with the DLL, the issue seems to be a mismatch between the current online data format (Apify) and the bot's deserialization logic for the year 2026.

        Could you please verify if the Apify data structure has changed and if an update is required?

        Thank you for your support.

            To provide you with a precise answer regarding this deserialization error, I need to check exactly how your parameters are configured and which version of the cBot you are currently running.

            Could you please share a screenshot of your parameters and the cBot version number?

            Since you cannot attach images here, please send them to me on Discord https://discord.gg/VcsszWc6z7 or upload them to a file sharing service and paste the link here. This will help me verify if the Apify endpoint or data format has indeed shifted for 2026.
