Option Master with IB account

Hi,

i have an active (not trial) IB trading account. i want to use protrader to trade stock options with better charts and analysis functionality, and am testing a trial version to see if it will work for me. i can already see that it is very powerful, but i am struggling a little.

I would like to use the option master, but I cannot seem to access data for any of my positions on it. it seems to stay empty. I have no problem on TWS mosaic, what am i not getting? I read elsewhere on this site that i might need a iqfeed subscription? how come if TWS can provide me an option chain when i select a position?

another quite simple thing i would like to do is to show the greeks in my watchlist as columns, but I can't seem to do this. i think the options master does it, but i can't get past the previous barrier (above) .

help, i am confused..! please dont tell me i have to pay an additional subscription to IQfeed to use PTMC to trade my stock options?

thanks
