Does anyone's system allow them to know when openbook has updated. For example you have open book open and it counts down to "0" then boom "update". then 10,9,8, etc.
For example if I pull up LEH and want to get a look at the open book it would be nice to know if it just updated 1 second ago or 8 seconds ago.
The 10 second refresh is a constant is it not? However not every open book updates at every 10 second interval during the day does it? I mean C may be updating then 2 seconds later JPM updates etc correct?
Anyone else want to offer up thoughts on how to profit from OB even with the 10 second delay.
Also if anyone could share whether or not they know when the 10 second update on open book hits that would be helpful.
(obviously the OB providers I have seen don't beep or flash or signal you when it has just updated, and since the NYSE likes to control this data and limit what other firms might do to enhance it as a trading tool, maybe nobody has this or maybe someone does, if they do please post or PM me. I am using OB more lately but still click through a lot of symbols and it would be extremely useful to me to know which OB quotes just refreshed vs. the really stale ones.)
As for anyone that wants to post, that OB is worthless and that real traders don't need it and all that B.S. Don't waste your time, the guys that are using it are using it for very specific types of trades and doing pretty well.
Am just trying to gain some knowledge for myself here as I mostly trade nasdaq and only recently have begun to use the book during dead times to find some opportunities in lower vol names.
