The pros of trading with First Securities include its wide range of financial products, such as equities, derivatives, and fixed-income securities, making it suitable for diverse investment strategies. The platform is regulated by TPEX, which provides some level of security for local traders. However, the cons include the lack of global regulation and transparency, especially with the "Unreleased" regulatory license number. The platform’s fee structure is also not entirely clear, which could make it difficult for traders to assess costs upfront. Furthermore, its limited international presence may not appeal to global traders.
