Which platform to use to DCA $100 monthly into USA/world stocks. Is it a good idea to use Syfe custom with (25% ARKK and 75% QQQ)? I'm holding CPSX via IB and aims to buy more cspx when market is bad

IBKR~ $0.35 per trade

For starting, with the small amount syfe will cost lesser, but once your amount become larger over the years, the annual fee still slowly build up~

And to me syfe select is kinda bad tool, you are forcing yourself to buy certain etf~

However they are releasing the syfe trade which gives you 5 free trade per month, may be that will suit you more if you don’t play margin
