US CFTC Forex Brokers, Copytrading, Metatrader 4 vs 5? VPS?

I’ve tested copy trading on MT4 in the past (paper money account). It was a few years ago. I can’t even remember the broker or the VPS I used.

I’m in the U.S. All I remember is that the number of traders available to copy on MT4 was WAY greater than the number offering MT5 feeds. Is that still the case? I assume it would also eclipse any other platform for copy trading Forex (like ACT.)

Can someone recommend a CFTC regulated US broker that MT version to use for copy trading? I assume none of the brokers including a free cloud-based MT login that supports copy trading? If so, cheap but easy VPS recommendation for low volume trader would be appreciated.

Don’t know much about copy trading or MT and VPs, but US brokers are really limited.

It’s IG, Oanda, Forex.com, Trading.com, and now Schwab.
