so it's almost 10pm Pacific time and i'm not sure exactly when this new price popped up, but the Interactive Brokers last price for SDS on trader workstation was $40.46 (which happens to be the the Wed. Nov 4 close). i say "was" because it just now reverted back to the Thurs Nov. 5 close price of $38.94. At first I thought SDS was still trading somewhere (eg, overseas) and that that price was feeding into IB Trader Workstation. But it appears this is simply an IB glitch. Has anyone else seen this error?
