Stake is an Aussie Fintech which allows to trade more than 3000 stocks and ETFs on the S&P500 and Nasdaq for free. There is no brokerage.
They make their money mainly by charging 70 pips when converting funds between AUD & USD ($0.7 for every $100 converted) but have a few other fees outlined here.
Been using them for over a year now (since their beta days) and reckon their offer unbeatable value as well as great UI and UX
They have (finally) launched their android app and running a one day referral promo to 'celebrate':
Droiders rejoice, we've made it into the Playstore! To celebrate, we're having a 24hr party where both you and any friends who sign up and fund today get $20.
Fund before 10pm today AEST and your money will be ready to trade TONIGHT. If you miss the 10pm threshold - no worries. You can give $20, get $20 until midnight.
Mod: Removed referral info. Referral system now set up for invite code.
The referral system was previously set up and disabled. Perhaps the old format expired. Please let us know what the referral info is : Format, benefits for referrer and referree. Please don't add comments with referral codes or solicit referrals until then, thanks.
