Can a PAMM-Trader disactivate the PAMM-service (refuse from participation in monitoring)?

Unfortunately, you cannot deactivate this option. However, if you want to register with the PAMM system as another participant (PAMM investor or PAMM trader, or vice versa), you just have to open a new trading account. InstaForex does not set any limits to the number of opened trading accounts. Soon, the option ""Hide account from monitoring"" will be launched and it will allow you to remove account from the monitoring list.
