Graham,
Thanks for the explanation. I think we may be trying to achieve
different things here. This is the description of the diferrent ways
of running QT (from the Amibroker site):
>>
QuoteTracker plugin currently works in TWO modes:
daily mode - plugin adds and updates the last (todays) bar with the
most recent quotes in nearly real time- it means that you have to
use it in conjunction with already existing end-of-day database.
intraday mode - plugin provides one day intraday historical data -
more days can be accumulated if AmiBroker with QT is launched
everyday so AmiBroker can save histories to its local database.
>>
I'm trying to get option one, just to add an additional 'live' bar
of data for the current trading day to my existing Metastock
database, so that I can see how my indicators are developing in real
time (are my stops being hit during the day, for example).
I think maybe you are using option two - the intraday mode?
