I've set up Quotetracker to use the feed from Westpac Broking and it seems to work quite well, but I've noticed that at best it seems to update the data in one big lump every 15-20 seconds. While this is acceptable for the time being, I have noticed when watching other trader's live videos on Youtube etc that their data is continually updating (streaming), with many movements a second. Is it possible to get this using Westpac Broking and Quotetracker? If so, how?
Also, I haven't as yet figured out how to set up Quotetracker to actually trade using Westpac (it isn't available in the dropdown list on the trading tab in settings), so if I want to make any trades I have to login to the Westpac Broking website (and close Quotetracker, as the website doesn't seem to want to allow two concurrent connections and they keep closing each other's session)... obviously this isn't ideal. Is it possible to configure Quotetracker to use Westpac or is this just not something that either QT or WB support?
On a different note, I was considering switching to Interactive Brokers as their brokerage/commissions are substantially lower. Any downsides to this? Is their feed also be substantially better in terms of streaming data? I'm a beginner when it comes to trading platforms so any advice would be appreciated.
