Api Error

Mischa Paalvast | 17 days ago

Hi guys,

I keep getting these errors;

API Error Message: Error retrieving backtest chart, please try again later

API Error Message: Error retrieving orders result, please try again later

At first I tried to use the ES mini futures:

future = self.AddFuture(Futures.Indices.SP500EMini, Resolution.Minute)

I thought maybe it had trouble to fetch Futures data so I switched over to the CFD but still got the same error.

self.contract = self.AddCfd("SPX500USD", Resolution.Minute).Symbol

Any ideas?

Thanks in advance!

To help Mischa resolve the API errors and code issues, here are some steps and observations:

API Errors: These errors typically occur when the system is unable to fetch backtest charts or orders due to server-side limitations or a large volume of requests. Here are some steps to potentially resolve these issues:
- Reduce Frequency of Requests: Lower the frequency at which data is requested by using a lower data resolution or reducing the number of securities being requested simultaneously.
- Check System Overload: Ensure that system overload isn't causing these errors by checking QuantConnect's system status page or waiting for less busy times.
- Keep Retrying: Given that the error message suggests trying again later, periodic retries could be helpful.
Code Adjustments: Based on the analysis, there were some issues in the code, particularly with the enumeration of futures. Here's a corrected version of the code:

class MischaAlgorithm(QCAlgorithm):
    def initialize(self):
        self.set_start_date(2022, 1, 1)
        self.set_end_date(2022, 1, 31)
        self.set_cash(100000)
        self.future = self.add_future(Futures.Indices.SP500E_MINI, Resolution.MINUTE)
        self.contract = self.add_cfd("SPX500USD", Resolution.MINUTE).symbol
    def on_data(self, data):
        if not self.portfolio.invested:
            self.set_holdings(self.contract, 1)

Data Availability: Ensure to verify your subscription to QuantConnect data feeds, especially for US futures and CFDs, as these may impact algorithm functionality.

Following these steps should assist in mitigating the API errors and aligning the code with QuantConnect best practices. If problems persist, considering reaching out to QuantConnect support can be beneficial.

Hello,

Same error message here. I think there is currently an issue with the QC platform.

Hi Narloc

There should be a temporary API connection issue back then. If this problem persists, please contact support@quantconnect.com
