Interactive broker data feed not working

Hi,

I connected IB data feed to Ami broker but i do not see any symbols.
Even in real time quote window I cannot add any symbol.

Do i need to take subscription from interactive broker to get data feed ?

I do not need historical data but real time data only to do trading.

Log into your IB account on their website. Go to the section where you select what real-time market data subscriptions you want. The monthly fees will be there for whatever you choose. After that, you won't have any problems with Amibroker / IBController concerning real-time market data for what you want to trade.
