I strongly recommend Pepperstone to service clients in Asia.
Their Australian office is ASIC regulated, excellent execution quality, and great customer service. There's a promo on right now for clients in Asia / Australia that makes your first 20 trades commission free if you use the promo link below:
That's a great way to test out their execution quality and platforms (cTrader, MT5, or MT4) without much cost. Consider that someone testing out trade execution quality on a $1M clip size (10 standard lots) would be saving ~$75 AUD per trade for 20 trades.. that's huge.
