I have upgraded FuturesTrader to support IB API 8.61 Beta.
Now, if you update your IB API to 8.61 you no longer need an external datasource to request historical data.
Select the symbol you want historical data from, connect to IB TWS, click download and after 1 or 2min you should see the message
At the moment I can request just 1 week of data from IB, but this might change in the future.
Be aware, that IB API 8.3 and IB API 8.6 are incompatible. So if you have programs, which require IB API 8.3 you should not upgrade.
