Yes, you can decline any investments that you are not interested in. I also have a PAMM account, I manages 5 PAMM investors since October. Pamm system is very profitable.

I think you are allowed not to accept the investment request in your PAMM account.

All the PAMM managers are allowed to accept and decline investments anytime.

Of course! You are allowed to accept and reject investments from other people.

All brokers allowed the PAMM manager to refuse any investments. The managers have the right to choose/

I asked my friend about this, and he told that it is possible to cancel the investment that you are not interested in.

If you are not interested to a specific investment, then you have the right to refuse nor reject the investment.
