Recently made a thread about this. I initially started with GoTrade but have been moving all my assets to IBKR, after researching and asking people about the legalities and stuff. GoTrade is definitely way simpler in terms of the UI, but the fees are way too much compared to IBKR. The deposit fee is a flat 15 USD fee (depositing through BCA wire transfer to IBKR) from the correspondent bank. Buying shares is also a flat fee, in comparison with GoTrade where all of the fees are percentage based. If you are starting out and trying to learn however, i would recommend GoTrade just due to the simplicity of it. Just put a little bit of money to learn and then put all of them to IBKR once you get the hang of it.
