Angelo, If you're just watching one symbol, it updates with every data value received from your data vendor. The "current bar", be it 1 minute, 5 minute or an hour, is continually updated.
Please note that, all though you can see what's going on, you really can't trade until the entire bar is history because that is when your signal, if you get one, is final (assuming your code depends on more than just the open of the bar). How much data is saved by AB is a function of the File->Database Settings and what interval you setup your database as. I use one minute and IB, but trade on 15 minute bars. Also note that Tomasz has explained that IB does not provide true tick data, but rather periodic "snapshots". The periods are quite frequent, like 1 second or maybe faster, I don't know. Just be aware it is not a true tick data source (which doesn't sound like a problem for your intended purpose). -- Terry -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Angelo Sent: Friday, August 25, 2006 09:37 To: [email protected] Subject: [amibroker] Re: Simulating the trading of a system in real time. --- In [email protected], jppt0k <[EMAIL PROTECTED]> wrote: > > Angelo, > > if you need to generate buy or sell signals, the Scan option with Run > every (you may set it to run every n seconds) is what you need.

Check if AMB can control if there is a BUY/SELL signal on every tick of price change (and not using historical price series, but in real time, with prices coming from my broker platform). I settled for a scan every 10 seconds (thanks for reminding that one minute was not the minimum of the range) and this is probably as near I can go to reality (or at least, to my idea of reality), without the IB demo account.
