Missing price data for CURE

To address the issue of missing price data for the ETF "CURE" in live trading, here are some steps and considerations based on the error message and relevant documentation:

1. Verify Data Subscription: Ensure that you have an active data subscription for the ETF "CURE". Sometimes, data subscriptions might lapse or change, affecting data availability.

2. Implement Warm-Up: Use the SetWarmup method in your algorithm's initialize method to warm up the algorithm with historical data before live trading begins. This ensures that your algorithm has sufficient data to make decisions as soon as it starts.

   def initialize(self):
       self.set_start_date(2023, 1, 1)
       self.set_cash(100000)
       self.add_equity("CURE", Resolution.DAILY)
       self.set_warmup(30)  # Warm up with 30 days of data
   

3. Check Data Availability: In the on_data method, use slice.contains_key(symbol) to confirm that the data for "CURE" is available before executing any trades. This prevents the algorithm from making decisions based on incomplete data.

   def on_data(self, data: Slice):
       if data.contains_key("CURE"):
           # Proceed with trading logic
           pass
       else:
           self.log("CURE data not available")
   

4. Review Custom Data: If you are using custom data, ensure that the 'Value' property is correctly set to provide accurate price data. This is crucial for the algorithm to interpret the data correctly.

5. Monitor Data Feed: Check for any interruptions or issues in the data feed from your brokerage or data provider that might affect the availability of price data. This might involve checking logs or contacting your data provider.

6. Log Data Events: Implement logging to capture data events and any errors related to data availability, which can help diagnose the issue.

By following these steps, you should be able to address the issue of missing price data for "CURE" in your live trading algorithm. If the problem persists, consider reaching out to QuantConnect support for further assistance.
