People with options trading experience, what are the platforms a beginner can use to trade options for both Singapore and overseas stocks?

The absolute best one is Firstrade, where they offer $0 commission on Options, Stocks and ETFs trading, great for extensive options traders.

Here are their fees

Interactive Brokers is a great option. They charge USD0.25 per options contract (USD1 minimum), but they charge you USD10 per month -- unless you make 10 trades a month or maintain an account minimum of USD100,000.

You can also consider Saxo Markets. They charge USD3 per options contract (U.S. markets) and have an office in Singapore to facilitate any questions you may have.
