I'm unsure how you are proposing to build a sustainable business with such low fees. Assuming you need say 5 full time employees to run something like this somewhat robustly, and back of the envelope your expenses are say 2 million a year (which doesn't afford you to pay anyone particularly well), you'll need a 160k users (!) and you are only breaking even. And you have no chance in hell to provide decent support for that many users in an area as gnarly as finance. You'll be facing a firehose of support requests all the time. I'm sorry to sound negative, I really wish you all the best, but even from your post it looks like you had little to no idea what you are doing when you started this (you didn't know stock tickers are ephemeral?). And yet you are asking people to trust you with their money? With the only selling point being that you seem to be unsustainably cheap? What made you decide that you have the knowhow to do this well and safely?
