You might want to check out Standard Bank OST platform. Its quite a nice online broker option if you're only going to invest in securities and ETFs.
Cheap option for ETFs is etfsa.co.za but their online system is horrible, worst than Satrix etc.
I use FNB Securities, but I am on a special pricing plan with my other accounts, so I don't pay any account fees, just brokerage, which works out to about the same as standard bank with the amounts I trade. (minus the monthly fee)
But keep in mind you can't buy any unit trusts with the above systems..
Well etfsa.co.za (This webpage is not available) so that's a no no.
Yeah, look if you want cheap, you can go Easy Equities. Simple and basic. That's why its so cheap.
There is a thread on Easy Equities that you might want to check out.
From the website:
Prices displayed on the website or the EasyEquities platform may reflect delayed prices, or may be the previous day’s closing price for that security as quoted by the recognised exchange. Your trades in securities will be executed at the prevailing market price, quoted by the relevant recognised exchange for that security, at the time we execute your trade as reflected in the Invoice (“Execution Price”). The execution price may be different to the quoted price, depending on how the security’s market price has moved during the course of the market day. We do not give any guarantee that the execution price will be at or near the quoted price.
That makes their platform absolutely of no help. So they seem like a no no too.
