You can choose everything, or just one. For Zulu, many brokers are available for you to choose from, and the minimum deposit as far as we know is $500. Meanwhile, Insta and Roboforex can be done with funds under $500. The plus side is you can get profit without having to bother with analysis, with the note of choosing a provider with a good track record. Meanwhile, the downside is that there are losses that you have to be prepared to bear.
Thanks
@ Afrian Sujadi:
If you choose a trader from Zulutrade, I think it's best to follow the Zulutrade platform, or adjust it to the platform of the trader you choose because the trading signals provided (buy or sell at a certain level, SL and TP) will be more accurate if they match the trading platform used by your chosen trader.
