Subject : Procedure Call or Argument is not Valid Posted : 5/2/2015 3:58 PM Post #35357
I have just installed OT 2015 and PR 2G on a new PC and I get the following error message when clicking on a symbol: "Error 5: Procedure call or argument is not valid. Occured in routine - COptionable .Save".
The error happens when 'On Demand Downloading' is checked under Data Settings and OT is attempting to load more data for the symbol.
After clicking OK on the error message the data for the symbol loads as normal.
I also get this error when trying to enter a trade using Trade Manager.
