Backtesting doesn't run

Based on the information provided, it seems like you're experiencing an issue with backtesting on QuantConnect. This could be due to a temporary issue with the backtesting system or a problem with your specific project or code.

Here are a few things you can try:

1. Check if there's a temporary outage or issue with QuantConnect's backtesting system. You can check the QuantConnect Status Page for any ongoing issues.

2. Try running a backtest on a different project or algorithm. If the issue persists across multiple projects, it's more likely to be a system-wide issue.

3. If you're using a custom algorithm, ensure that your code doesn't contain any errors or infinite loops that could cause the backtest to hang.

4. If you're using a large dataset or a long time period for your backtest, it might take longer to complete. Consider reducing the size or duration of your backtest to see if that helps.

5. If you're a paid user, you might want to consider upgrading your backtesting node for faster backtest speed.

If none of these steps resolve your issue, I recommend reaching out to QuantConnect's support team for further assistance. They can help investigate the issue and provide more specific guidance.

There seems no incidents on the page so far. I just used the default template code, but still seeing the same issue.

# region imports

from AlgorithmImports import *

# endregion

class MeasuredFluorescentPinkShark(QCAlgorithm):

    def initialize(self):

        self.set_start_date(2022, 11, 19)

        self.set_cash(100000)

        self.add_equity("SPY", Resolution.MINUTE)

        self.add_equity("BND", Resolution.MINUTE)

        self.add_equity("AAPL", Resolution.MINUTE)

    def on_data(self, data: Slice):

        if not self.portfolio.invested:

            self.set_holdings("SPY", 0.33)

            self.set_holdings("BND", 0.33)

            self.set_holdings("AAPL", 0.33)

I'm sorry to hear that you're having trouble running a backtest on QuantConnect. Your code seems fine at first glance.

Here are a few things you can try:

1. Ensure that you're using the correct syntax and that there are no errors in your code. The code you've provided seems to be correct, but it's always a good idea to double-check.

2. Try running a backtest on a different project or algorithm. If the issue persists across multiple projects, it's more likely to be a system-wide issue.

3. If you're using a large dataset or a long time period for your backtest, it might take longer to complete. Consider reducing the size or duration of your backtest to see if that helps.

4. If you're a paid user, you might want to consider upgrading your backtesting node for faster backtest speed.

If none of these steps resolve your issue, I recommend reaching out to QuantConnect's support team for further assistance. You can do this by clicking on the "Support" tab on the left side of the IDE and submitting a support request. Make sure to attach your project to the request and grant permission for the support team to review it.
