Unfortunately, when you updated your Tradestation version it created a new directory/folder which the TAS Indicators was not installed in that referenced directory/folder
THE CAUSE:During installation of the TAS Indicators, the files were installed in the correct directory/folder to match the user's version of TradeStation. THE PROBLEM:After update of the Tradestation and then attempted to add the TAS Indicators to the chart, the TradeStation platform does not show any list of TAS Indicators on the indicators list.
