// Specific error handling for: Data feed interruption
Log($"Error: Historical data request failed - {ex.Message}");
// Recovery strategy: Use cached data and retry connection
// Use cached data as fallback
var cachedData = dataCache.GetLatestData();
if (cachedData != null)
{
ProcessData(cachedData);
Log("Using cached data while retrying connection");
ScheduleRetry();
}
// Continue with fallback approach
return HandleFallback();
}
catch (Exception ex)
{
// General error handling
Log($"Unexpected error: {ex.Message}");
throw;
}

RECOVERY STRATEGY:
Use cached data and retry connection
MONITORING:
- Log all errors for analysis
- Track recovery success rates
- Alert on repeated failures

}
catch (Exception ex) when (ex.Message.Contains("Parameter validation failed"))
{
// Specific error handling for: Parameter validation failed
Log($"Error: Invalid learning rate value - {ex.Message}");
// Recovery strategy: Use default parameters and log warning
// Use default parameters

How do I implement the RequestAdditionalTime method in IIsolatorLimitResultProvider?
|
The RequestAdditionalTime method in IIsolatorLimitResultProvider Requests additional time from the isolator result provider. This is intended

resources available to fulfill the specified number of minutes. [Subscription] Use this method to subscribe to data or add components.. Implementation:
```lean
def RequestAdditionalTime : IIsolatorLimitResultProvider → Type := sorry
```

Handle this error scenario in Lean:
ERROR: Data feed interruption
CONTEXT: Historical data request failed
REQUIRED: Implement error handling and recovery
Provide robust error handling code.
|
ERROR HANDLING IMPLEMENTATION:
```csharp
try
{
// Primary operation
// ... main logic here ...
}
catch (Exception ex) when (ex.Message.Contains("Data feed interruption"))
{
// Specific error handling for: Data feed interruption
Log($"Error: Historical data request failed - {ex.Message}");
// Recovery strategy: Use cached data and retry connection
// Use cached data as fallback
var cachedData = dataCache.GetLatestData();
if (cachedData != null)
{
ProcessData(cachedData);
Log("Using cached data while retrying connection");
ScheduleRetry();
}
// Continue with fallback approach
return HandleFallback();
}
catch (Exception ex)
{
// General error handling
Log($"Unexpected error: {ex.Message}");
throw;
}
```
RECOVERY STRATEGY:
Use cached data and retry connection
MONITORING:
- Log all errors for analysis
- Track recovery success rates
- Alert on repeated failures
