It is all up to you and your comfort levels. Maximal drawdown is the lowest point in your account balance during the testing. I know that clients of hedge funds do not tolerate drawdown, so this has to be very low for them. Profit factor is the total profit divided by the (total losses)*-1. I personally like to have a very high profit factor, but the most important to me s a low drawdown.
Hope that helps,
