Ever thought about just setting up a sub-account? It's heck of a lot easier than opening a new account. Here's the instruction. https://faq.ampfutures.com/hc/en-us/articles/10798190609047-Steps-to-set-up-Sub-Account
I'd be careful with that approach. A few years ago, I remember reading a complaint from a trader on the AMP forum: He had a personal account at AMP and was trying to open a second account. He then mentioned something that suggested he was thinking of trading someone else's account. Not only did AMP Compliance deny his new account request, they also closed his personal account. Once that happens, there is no forgiveness, no way to reverse AMP's decision to cut you loose. ...recent regulation is that you must TRADE YOUR OWN ACCOUNT or ACCOUNTS. Multiple accounts not funded by same bank raises a red flag also multiple routing can trigger Pro Rates. you could also be trading other people funds which is not authorized or allowed. IMO, it's not worth the risk.
Copy trading is not the same as "trading for others". Otherwise they would've shut down sites like collective2, isystems etc long time ago. Unless you were thinking of actually accessing their accounts to trade, then that's wrong..and dumb.
