@ Irawan:
ETX Capital is a UK broker regulated by the FCA, one of the credible regulatory bodies. Its profile can be read at: Broker ETX Capital
This broker with multi platforms, which has been around since 2002, also took over customers from Alpari UK which went bankrupt due to the SNBomb in January 2015.
ETX Capital is a good broker that is quite well-known in Europe, but less popular in Indonesia. As far as I know, there are no IBs for Indonesia yet. If you want to try trading with this broker, you are welcome to.
