To Silva,
All the brokers you mentioned above are quite popular among Indonesian traders. Both FBS broker and XM broker have long been trusted by millions of traders in the country. Although both brokers are included in offshore licensed brokers, this does not make their reputation bad. In fact, until now these brokers are still actively operating with a fairly good reputation (no negative reports such as fraud or scams).
Although they are trusted by millions of traders, it does not mean we should be careless. We must remain vigilant about the worst-case scenario, considering that offshore licensed brokers do not have strong regulatory security guarantees. Therefore, we advise you not to transact in large amounts (no more than USD 5000) with brokers whose regulations are offshore.
Hope this helps
It seems like many Indonesian traders use FBS. Also Instaforex. But there seem to be a lot of complaints about Insta.
