Lowest Cost Broker <5k
As far as I can tell EasyEquities is the lowest cost share trading platform for trades <$5000 (after that superhero is cheaper at $5 fixed). It is also the only broker I have found to offer no minimum investment value, you can literally buy or sell 1 share!
If you wish to dabble in small value investments or dollar cost average your investments, this could save you a ton in brokerage.
You can also trade US Stocks and set up automated recurring investments which is neat.
Is it CHESS sponsored?
No, easyequities has a similar HIN model to superhero, is an authorised rep of Sanlam (AFSL 337927), same as superhero, thinkmarkets, and a number of other brokers.
Make sure you give them a couple of days for the $10 to be deposited - if it doesn't show up raise a support ticket and they will credit you.
