Currently, OEC is supporting both 3.4 and 3.5 versions of the OEC Trader.

Version 3.5 was introduced to support stocks, ETFs, options, and mutual funds and is not a mandatory upgrade. However, to trade these instruments you must use version 3.5. Follow the user's guide link below to explore the new features of version 3.5.

Version 3.4 is still supported and users can continue to run this version. As noted above, this version will not support equities accounts.
