quote lag, take a while for orders to appear in TWS after submission. i place order to sell @ 3.9 on some low volume nasdaq stock (it was the best offer at that time ) and it takes about 30 sec for order to appear. takes sometimes 2-5 min for data to appear, after you type ticker in TWS. sometimes it show you position,some bs PnL,high,low,volume, but no bid\ask
bid/ask didn't show on some of my stock symbols this morning. Re-started TWS, problem went away. build 882 with java 1.6.
