Re: [amibroker] Why is NinjaTrader Better at Backfilling IB Data?

[Tomasz Janeczko <groups@xxxxxxxxxxxxx>]

Hello,

Also read this (to the VERY END of document):
http://www.amibroker.com/ib.html

With default settings AmiBroker attempts to backfill not 5 days but *30* (THIRTY) days
and that is 6 times more than IB capability per single request (IB allows only 5 days in one request).
To get 30 days program needs to split it into 6 requests.
So if you are comparing to 5-day only backfill you are comparing apples to oranges.
So you would  need to change backfill length to 5 days in the plugin status menu
as explained in the document referenced above.

Best regards,

Hello,

It works just fine with AmiBroker and exactly same speed (or better).
Something is wrong with your setup (probably incorrect database settings).
You need to configure database exactly as shown in the video:

I always had problems backfilling data from Interactive Brokers into AmiBroker, but then I started using NinjaTrader and I haven't had much problem with it. In NT, I am able to load up to 20 different futures charts with 15 days of 5 minute bars without a problem, and it only takes about 1 minute to do so. I just tested it with AmiBroker using only 1000 5 minute bars and it keeps choking on a single symbol. This makes me think that either something is wrong with the IB plugin for AmiBroker, or NT figured out a clever way around the throttling issue. Is there anyway we can look into the IB plugin to make it work better? I really want to use AmiBroker with my IB datafeed.

Thanks,
Chris
