I am about to open a daytrading account and I narrowed it down to 2 brokers: Interactive Brokers and Lightspeed. I'm wondering if there are people who prefer Lightspeed to IB and why? Lightspeed appears to be slightly more expensive but I do like their platform better (perhaps because I practice on it since it works in real time as opposed to the IB's demo, which seems to be totally random). Also IB is giving me a lot of grief with financial suitability requirements bullsh!t with approving my account for margin. (What does it matter how much money I have overall if I'm giving you 25 grand? - really pisses me off!). On the other hand I hear a lot of great things about IB and I'm wondering if it's better than Lightspeed when it comes to functionality/speed/ease of use and other things that matter. I intend to trade stocks only. Thanks.
