I read a bit about IB market data fees in non-US stock market. And I would like to take this opportunity to comment about it. There is no stock market data which is free (except US stock market but free only if you meet the commission requirement). The majority of the stock market costs more than 10 USD. These are the stock market which costs more than 10 USD (the dearest being ~32 USD or 320% difference): Australian Stock Exchange AUD 37.50 Hong Kong Stock Exchange HKD 200.00 Osaka Stock Exchange (GL) YEN 1200.00 Tokyo Stock Exchange (GL) YEN 2400.00 German Stock Bundle (excl. SWB) Level I EUR 15.00 German Stock Bundle (excl. SWB) Level II EUR 20.00 Euronext Data Bundle- Level II EUR 30.00 Venture Market by Price Level II CAD 12.00 Canadian Stock Bundle Level I (Non Canadian Residents Only) CAD 13.50 I don't know much in the US. But 10 USD is rather expensive according to my country living standard (comprises 10% of the salary of the low income groups). The deal in US stock market is competitive in my opinion. You can save that cost if you meet certain commission which is another big plus. However it sucks like hell in most stock markets. No exemption. Damn expensive especially the Australian Stock Exchange which cost as high as 32 USD. I can get at least 50% cheaper, getting much deeper discount if I subscribe multiple market data. When you subscribe to multiple market data, the cost does add up. Seeing the price of other competitors (data providers), they should be able to earn some good money even after offering a competitive price, don't they? I believe IB earns some handsome profits on data subscription too. I think it makes some sense to subscribe to third party datafeed. However the bad thing is IB forces you to subscribe expensive market data if you still want to trade on that market via IB. I say " IB forces you" because it pops up a warning every time you place or change an order, telling you to subscribe market data first before you should trade. The popup annoyance will make you impossible to trade. That's why I said "IB forces you to subscribe its expensive market data", probably to their own benefits.
