I just checked the fees for various stock brokers because I wanted to find out who is the cheapest. I found that commission makes a big difference to profits.

Most importantly, some brokers have a minimum daily fee, while others do not. If you’re buying stocks in small amounts, you should choose a stock broker with no minimum so you don’t end up being charged high commissions that aren’t worth it.

So I tried to compile information from 10 of the biggest brokers, such as Liberator, which offers 0% commission and no fees for trading through the app, with no minimum at all. SBI Online charges 0.075% for Cash Balance accounts and also has no minimum. Bualuang charges 0.15% and has no minimum as well. Krungthai XSpring charges 0.15% and 0.20%, and both have no minimum.

But other brokers, such as Kasikorn, Thanachart, UOB, and Phillips, all have minimums of 30–50 baht per day. If you buy in small amounts, you may end up paying commission at a higher proportion.

A stock broker with no minimum fee is definitely cheaper. If you’re an investor with a smaller amount of capital, you can save a lot on these fees. Choose one that fits your own trading style—whether you trade often or trade less, the commission can vary greatly.
