RBOB Pricing Incorrect

[aarone]

Yesterday I charted RBOB Gasoline Futures and found that the pricing did not match my broker(IB) data, or DTNProphetX data. It was about 7 cents higher, thou the movements and chart formations were identical to the other charting recources. Is this still the same contract? Any idea why the price was off? What are the live trade implications if I wanted to trade from NT(ie entry price form NT chart or actual broker traded price)? Anything I can do to correct this?

Keep in mind, to get RBOB thorugh Interactive Brokers, I had to edit the instrument and used RBOB Gasoline, NYMEX, with IB set to RB. I also tried to set the financial futures as well as the GAS contract in NT, but could not get any data for those through IB. I only have DTN at work, so that's not a connection option right now. Admittedly, I don't know what that 'GAS' contract is either? 100 lot?

Any help appreciated... Thanks!
