No, I haven't got OptionTrader yet. The trading platform I'm using is TradeMonster.com. There's a row of buttons at the top of the options page that allow you to view whatever month or week chain you choose. You'll only get one week at a time except for Thursday and Fridays when 2 weeks will be displayed, the current week about to expire and the following week. OptionTrader might have the same thing where you toggle the chains you want to view, you'll have to contact Support on that one..
There is no new weekly options issued for the week when monthly options expire either..
All the best,
