It's important to keep in mind that for anyone trying to pass funded accounts, you might end up blowing more accounts than what the client has paid for. Each exam comes with a cost, and this can be a limiting factor.
Additionally, prop firms are not fond of services from professional traders or copy trading systems. They monitor accounts closely, keeping track of details like the time the trade was opened, the symbols traded, and the IP address used (you must ensure you’re using the same IP location as your client). In some cases, they may even ask how you managed the account or which EA you're using. This is to prevent the use of the same EA on multiple accounts, as it helps them minimize their funding risk.
This is a solid guide, but it’s not suitable for the average trader. Personally, I wouldn't be able to do it.
