Data request failed: unable to access cache data.

Sometimes you can get the message: ”data request failed: unable to access cache data” in Tradestation. An easy solution to chart issues is normally to hit ”Ctrl R”. Which refreshes your chart and solves most issues that come up. However, sometimes you might get an error message that says: ”data request failed: unable to access cache data” and shows a black screen.
