[amibroker] scanning live data

Trading Reference Links


I have been playing w/ a concept that looks promising (on back 
testing) that relies on 3 minute data bars.

I can manually enter watch lists each day of the 100 or so stocks 
most likely to trigger a signal (those that have earnings reports, 
upgrades, etc)  but there could be others that occur to other stocks 
during the day.

I currently am using esignal for my real time data but am limited at 
their lowest level.   

I don't have a grasp on how grabbing and scanning live data would 
work.

Questions:

1. If I paid esignal to retrieve thousands of stocks at a time can 
amibroker scan through thousands of stocks every minute to see if a 
trigger has been hit?
2. If I wanted to keep scanning the entire market (for argument sake 
say 6000 stocks) do you know how many I'd need to buy from esignal?  
For instance, they have one price tier that says I have unlimited # 
of symbols, 1000 at a time.   Could Amibroker grab 1000, scan 
through it in, say, 10 seconds, then do this for the next 1000 and 
so on?    So, if I had 1000 at a time viewable I'd get through 6000 
stocks every minute?
3. Is there any better way to do this?  

Thanks; any explation or insight would be helpful.

Mike
