I just updated TWS to a newer version and noticed when I booted up I had all kinds of HUGE profits. Being the investigator I am I found out 1 second later that these 'profits' are due to all equities having an avg. buy/sale cost of 0 !! now, when I used to log in on different computers, the buy/sale avg. price info was always there, so I assume that this info is stored centrally with IB. Is this a problem of a simple server failure (I hope so) or is this data sweeped every now and then or ... ? Anyone know? Tiki
