US brokerage for International trader

[Guest]

Hi let me introduce myself first, i'm Indonesian and live in Indonesia. I currently trade with Interactive Brokers (IB) and enjoy it. I use thinkorswim (tos) paper account to help analyze my position because my internet provider block some IB feature such as risk navigator, etc.. I love thinkorswim platform and many people told that we can negotiate their commission. So, i considered to open an account with TDA but I found that TD Ameritrade can't process applicant from my country. Is someone at this community can help me to open an account at TDA or share another analysis platform?

I see that tradestation and livevol can accept Indonesian applicant, but their commission is more expensive than IB.. If someone trade with them, please share your review about those brokerage..

Thanks a lot.
