Is it possible to post a chart of that option and the run from 1 to 175? Thanks

What kind of model is used to price SPX options, their volatilities and skew? Is there a model that calculates the change of IV over time (IV surface)? Thanks

@jeb9999 Thanks for the links. I always thought that IB holds the GTC order on their servers and submits these orders each day. So I was wrong :-( Thanks

Hello, I'm trading ober IB and oftenn using good till canceled orders. GTC orders aren't supported by Globex and the order is sent by IB to the exchange at the opening. I want to be on the first place in the orderbook and therefore it's important to enter the orders faster than others...

@DestertTrader Thanks a lot for your detailled answer. Election deadline was Dec. 19th Election was on Dec. 23th. One thing is confusing me. On Dec. 22th I had 3100 short GW and I bought them back that day. My broker statement says that it was a "closing buy" and for the following 8...

Hello, can anybody explain how the GW options are priced? Puts have a much higher IV than the calls and there is a pending merger with "PDS". Thanks

@dmo Thanks for the good link.

It's possible to short GM. Not all the time, but it is possible (@ IB)
