On my TWS, SPX shows a close of 1406.27. The CBOE gives 1409.84. Please give accurate SPX prices... nitro
TWS has been messed up for the last few days... not to mention the backfill -- seriously considering a paid datafeed... guess you get what you pay for ?
Sad to say, you may be right. One day, a week or so ago, I think maybe it was a Monday or Tuesday, I had problems with ES. The quotes just suddenly dropped out. Prices were just frozen on the screen. That could be a real bad deal in some circumstances
