If you have resident visa or permit living in Indonesia, you can buy stock in Indonesia Stock Exchange, the only stock market in Indonesia. Although some brokerage company may not ask those letter, but better to do research before trusting brokerage company. It is a must to have resident visa and tax number or NPWP to register in IDX.
Many foreign brokerage had register in IDX, you can check on IDX website whether those brokerage operate also within your country. But again always double check the performance of those brokerage through IDX site and usually IDX publish their activity or sometimes IDX suspend also if found irregularity on those brokerage.
Technology had change a lot in IDX so you will find real time market activity on all brokerage. It will help you find a good stock to start investing in Indonesia. And also kindly always careful choosing brokerage based on fees, because some brokerage give very less fees but hide something behind. Always read all their fees, not only for buying fee and look for testimony from other member for security reason.
Requirement to buy stock are very simple, I think same thing in your country also. Have a copy passport, sign agreement letter with brokerage, pay deposit on your securities account and wait till your account have approval.
For beginner better start with small amount, just to feel how the market flow. Although all market are the same like in your country, in which market drive by "whale", So always buy stock on the "dip" and sell the stock on "rally", this is the important point to save your money. All here are to gain the profit and not to lose.
Always keep enough money for reserve when market "bearish" and don't catch the falling knife, buy when really market stable and always research. Sometimes good news doesn't mean anything than the "whale" try to sell their stock.
