上周打电话给IB，刚刚又打电话给Questrade，比较了一下，买ETFs还是去Questrade比较实惠。ETF免买的commission fee，而且电话一下就打通了，接电话的人解释得很清楚。打给IB，告诉我会把我电话转给她加拿大的同事，两天都没动静。户开了一半，搁浅。。。
Questrade有$5000的软门槛是这样的，如果账户里现金和stock市场价加起来不足5k，账户里也没有任何买卖点话，会收取inactivity fee， 一个季度$24.95, commission fee按照trade收取，（之前听论坛的大侠说到过），$4.95－9.95之间。ECN费不是Questrade收到，是exchanger收的。可以通过设定limit price规避这个费用。即使收取，金额也不大。
Questrade网站发现一个promo code分享。感兴趣的到网站看具体说明。

QuestTrade买ETF不收费，但是卖的时候收费，加上ECN费用，也不低。
demo一笔要收20.39USD, 而且也不把ECN费列出来？
