Hi Jim,
I was going to answer before but there are some complex issues here and was hesitant because of the detail necessary to answer (am i'm still experimenting myself) but here are some comments....its always good to experiment yourself on backups and get to know whats going on first hand.
>1) Can I expect data lag and how much using the IB-QT-AB Pro realtime
>setup? I would have about 5 charts open and streaming.
It depends on whether you are using dialup or cable. I've been using this configuration over dial-up and with 10 tickers and surprisingly have found it very good. The speed of data flowing from IB seems to be quite ok.
>2) Are there any problems overwriting the intraday IB data with Lycos
>intraday every night?
There is a section in the users guide that talks about this practice and from my understanding of your requirements it should work ok
Users Guide: Tutorial-->Updating Quotes-->How to use AmiBroker in real time mode
(Read it all but in particular the section near the bottom titled: 'Things you should NOT do, or you should do very carefully')
>3) How much lag can I expect for the AFL formula (signal) to react to
>intraday data. Can I set it up to signal on 1 or 2 tickers (charts),
>the other charts are indexes?
I think the minimum time interval is 1 minute set in AA. You can set it up to produce a signal against various tickers by putting those tickers in a watchlist and setting the filter to that watchlist. If you want to see a signal in the chart itself then you could create a custom indicator that plots the buy sell short cover arrows.
>4) I installed a seperate instance of AB to another directory
>(/AmiBrokerRealTime) Amiquote appears to retain it's settings across

Installing two instances of AmiBroker is not something I would have done. If you are using Realtime then all you need is the realtime version installed for both RT and EOD data.
When you create an EOD or a RT database the data component is seperate but there are some components that are shared like Indicators, preference settings and default settings etc (this is a pain I know)
If you want it seperate you might have to put it on another PC.
>5) Any comments from users of this setup please feel free to comment.
I've just completed a trial of eSignal and will move to them as soon as possible, it really is the way to go but for now IB/QT/AB is the method I have to use and it does work.
There is one other issue that i'm currently not clear on and am in the middle of testing and that is the importing of 1 minute data from Quote.com
The problem is this: If you use QT as your datasource then your tickers will not have the option to store the data locally so how do you then import data from Quote.com and have it hold within a database.
I ran an autmation script over all the tickers to set the following property DataLocalMode = 1 (store locally)
Just prior to importing each time from Quote.com I run an automation script against all he tickers in this database to set the following flags DataSource = 1 (local only) then after importing, set it back to DataSource = 0 (default)
I'm not sure there is not a better way to do this but at the moment everything is working well. I'm open to suggestions from TJ or others on a easier (more correct) way to do all this that i'm currently just not aware of.

William Peters

Subject: [amibroker] TJ Help : AB Professional Upgrade
Hello
I am an AB EOD 4.0 registered user, going realtime (must upgrade).
I currently use IB-Quotracker and AB EOD for signals EOD.
I trade intraday using IB fed into QT (10 ticker symbols only).
I want to use my AFL formulas to provide real time signals on 1 and 3
minute charts in Amibroker Professional. "IB-QT-AB Pro"
I have considered Tradestation 7.2, however I do not trade intraday
every day, probably more like 8 or 10 days per month of "possible"
intraday trading (when I am not travelling-job), so spending $120
bucks/month makes me cringe (as well as learning another "not so easy
language").
I would use Lycos (free) for backfill of intraday data every night in
order to keep the database up to date.
Questions:
1) Can I expect data lag and how much using the IB-QT-AB Pro realtime
setup? I would have about 5 charts open and streaming.
2) Are there any problems overwriting the intraday IB data with Lycos
intraday every night?
3) How much lag can I expect for the AFL formula (signal) to react to
intraday data. Can I set it up to signal on 1 or 2 tickers (charts),
the other charts are indexes?
4) I installed a seperate instance of AB to another directory
(/AmiBrokerRealTime) Amiquote appears to retain it's settings across
directories? When I opened my EOD AB (/AmiBroker) Amiquote showed
Lycos 1 minute for download settings instead of my usual Yahoo EOD.
How can I fix this so I don't accidently "corrupt" the databases?
I would like the EOD and Intraday databases to be totally seperate.
5) Any comments from users of this setup please feel free to comment.
Thanks!
Jim
