Correcting Runtime Errors in Indicators Due to Maximum Number of Bars Study Will Reference Setting

Runtime errors can occur if you incorrectly define the maximum number of bars back (Max bars back) an indicator references instead of using the auto-detect feature. The reason for the runtime error is displayed in the Runtime error window. The most common cause of a runtime error is when an indicator needs to reference more bars of data to perform its calculation than specified by the user-defined Max bars back.

A runtime error automatically disables the indicator by turning its status to Off. To correct a runtime error, you must modify the Max bars back the indicator will reference to either Auto-Detect or, if you still want to specify the Max bars back a study references, enter a value that allows the indicator to complete its calculation. Once this is corrected, you must also enable the disabled indicator. For more information, see Disabling an Indicator.
