Hi - From yesterday my algo that was running normally stopped working and shows this error that is related to the data I assume. I really appreciate it if you could help me with it. The error is as below:
[ERROR] FATAL UNHANDLED EXCEPTION:Engine.Run(): Error running algorithm System.ArgumentException: Unable to locate next market open within two weeks., at QuantConnect.Securities.SecurityExchangeHours.GetNextMarketOpen(DateTime localDateTime, Boolean extendedMarket) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Securities/SecurityExchangeHours.cs:line 317, at QuantConnect.Scheduling.TimeRules.<>c__DisplayClass16_0.<AfterMarketOpen>b__1(DateTime date) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Scheduling/TimeRules.cs:line 168, at System.Linq.Enumerable.SelectEnumerableIterator`2.MoveNext(), at System.Linq.Enumerable.WhereSelectEnumerableIterator`2.MoveNext(), at QuantConnect.Scheduling.ScheduledEvent.get_NextEventUtcTime() in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Scheduling/ScheduledEvent.cs:line 80, at QuantConnect.Lean.Engine.RealTime.BacktestingRealTimeHandler.<>c.<GetScheduledEventsSortedByTime>b__11_0(KeyValuePair`2 x) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Engine/RealTime/BacktestingRealTimeHandler.cs:line 158, at System.Linq.EnumerableSorter`2.ComputeKeys(TElement[] elements, Int32 count), at System.Linq.EnumerableSorter`1.ComputeMap(TElement[] elements, Int32 count), at System.Linq.EnumerableSorter`1.Sort(TElement[] elements, Int32 count), at System.Linq.OrderedEnumerable`1.GetEnumerator()+MoveNext(), at System.Linq.Enumerable.SelectIPartitionIterator`2.ToList(), at QuantConnect.Lean.Engine.RealTime.BacktestingRealTimeHandler.GetScheduledEventsSortedByTime() in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Engine/RealTime/BacktestingRealTimeHandler.cs:line 156, at QuantConnect.Lean.Engine.RealTime.BacktestingRealTimeHandler.Setup(IAlgorithm algorithm, AlgorithmNodePacket job, IResultHandler resultHandler, IApi api, IIsolatorLimitResultProvider isolatorLimitProvider) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Engine/RealTime/BacktestingRealTimeHandler.cs:line 52, at QuantConnect.Lean.Engine.Engine.Run(AlgorithmNodePacket job, AlgorithmManager manager, String assemblyPath, WorkerThread workerThread) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Engine/Engine.cs:line 291

Hey!
Seems like a Lean bug related to a recent change. Could you please share, here or with support, and algorithm reproducing the issue?
Thanks, we will fix this ASAP

Hi there, I got the same issue with an old algo that use to run with no issue (though I am back to QuantConnect just today after 1+ year away, so the issue might have been around for longer). Were you able to sort it?

Hey!
Believe the issue was because the algorithm was trying to use ‘TimeRules.AfterMarketOpen/BeforeMarketClose’ for markets which do not close, like crypto or custom data, instead can use 'TimeRules.At(9, 30)' for example. Note it's also not possible to place ‘MarketOnOpen’ and ‘MarketOnClose’ type of orders for these assets for the same reason.
