Backtesting with IB intraday data

[arzoo]

I currently use IB and read it can be used to provide data for backtesting with NT. I'd like to know how far back the historical intraday data from IB works with NT.

And, do you have to 'collect the bars' or are they imported from TWS?

Thanks.

Welcome to our forums arzoo, historical minute and daily data can be downloaded from TWS / IB if you're connecting to a live account (not their free demo).

Tick data needs to be collected live with NT, as the connection would not provide a backfill for it.

I believe their minute data on the servers goes back about a year.

Thanks Bertrand.

I'll give it a try. Hopefully I'll be able to connect and test without too many problems.
