I was able to negotiate 75% payout from 50% I'm trading high volume ETFs.

Hi. I just joined Trader2B and asked the same questions in their chat. They are open and honest and they want traders to make money for them. You win, they win. Once you pass the challenge you get your money back once going live. The payouts I believe, and you can ask them, are something like 50% under $5,000 so you would keep $2,500. If $10,000 a month which is possible you get to keep 90%. I get it since it's their money you get to trade with and you get your money back once you pass the challenge. I would reach out and ask them many questions on the chat as you can and I recommend getting a copy of the transcript sent to your email. Hope this helps and good luck!
