I have a long running issue with TWS spread orders- Sometimes my spread orders are displayed, and sometimes they don't show up at all. Check out this example from today: <img src=http://www.elitetrader.com/vb/attachment.php?s=&postid=3823495> I'm bidding for a 5-lot at -1.70, so the displayed bid size shouldn't be less than 5 total. Yet, this spread is quoted as having a bid size of only 3 contracts at that price. How? Why? Where's my size? In other words, whenever I put in an order to buy or sell any given spread, sometimes my order is displayed in the quoted bid/offer for that particular spread, and sometimes I'm completely invisible for some reason. Why would my orders ever be invisible? Anyone understand what I'm talking about? Anyone having the same problem? Thanks and have a nice day!
