Just noticed the Thai broker fee structure. It turns out that when you buy only a small number of shares, the commission can be quite significant. But if you allow for a minimum fee, you may end up paying more than you should.

Judging by the current market, the broker with the lowest fees is likely Liberator, which offers 0% commission for trades made through its app, with no minimum fee—extremely cost-effective. SBI Thai Online is also interesting, with a 0.075% rate for Cash Balance accounts and no minimum fee, which is very economical.

If you want full-service support, Bualuang and Krungthai XSpring are also options. They charge 0.15% commission for Cash Balance accounts with no minimum fee, so even small purchases won’t incur additional commission costs. Most other brokers charge a minimum of 50 baht, which means you need to buy shares worth at least 33,000 baht for the costs not to increase.

Broker fees really matter because they directly cut into your profit. If you buy shares frequently, you should choose a broker with low or zero commission fees and no minimums. It’s better to review the details of each provider before deciding to open an account.
