I have the latest version, and, after running IB Gateway for a few days, in conjunction with excel DDE, I have a problem with the "tickers" requests. They work fine only if I have a relatively fresh IB Gateway session. After a few days, on the "tickers" sheet, High, Low and Close are not showing any longer, and unless I reboot IB Gateway, there is no way to make them appear again. Did anyone have the same problem and did you solve it?
