Hi, I too experienced the same 2 problems.
As regards to the backfill problem, I resolved it by backfilling through the AA window first, as opposed to manually pacing through the symbols: I run a simple exploration with "wait for backfill" switched on, on all quotations. Once this is done all quotes are updated and streaming. I have not yet found a solution for the IQFeed delay. All I can say is that it appears when there are a considerable number of streaming symbols - if I have 5-10 symbols only which are streaming then the data is fine, but if I run the backfill on all my database (approx 450 symbols) then I am also experiencing a huge delay. I do not think this delay is due to the connection speed - I am currently putting it down to the processing speed of my PC and am looking to upgrade, but I am not sure this will resolve the problem. I currently work around this by only subscribing to the symbols I will be using for the day (by running the above routine I mentioned only on a watchlist), then I update all the other symbols at the end of the day in order to stay updated from a historical perspective. hope this helps. Let me know if you find out something else about the IQFeed delay :) claude --- In [email protected], "gsmservplus" <[EMAIL PROTECTED]> wrote: > > hello, > > AB 5.20,windows vista,iqfeed client 4.4.0.3,virgin uk broadband > internet provider with up to 3 Mb speed. > > my problem is: when i load my iqfeed data base after some time i get > time delays on my stocks, forex ant futures RT data compare with my > PC time.every time delays are different from couple secs to over the > minute.as longer i`ve got AB and IQfeed opened as bigger delay is.but > it happens not always,but very often.IQfeed said is everything > alright with my data and could be problem with software or ISP. > p.s. time difference between IB TWS and my PC time is only couple(1-3 > sec.)seconds and never changes. > > > another problem is: when i start AB and start go through my tickers > to backfill current day data(as i understand it can backfill only 5 > tickers at the time, so every time when i start AB i`ve got to go > through all my database,i have around 200 tickers database)sometimes > some tiskers gives wrong data, i mean, only one very long candle for > current with huge volume in hourly chart.after i start "force > backfill"for those wrong ticker it gives right data then.and again it > happens not always, but very often. and IQ feed cust.service told me > could be problem with AB. > > any ideas about those two problems? thanks >
