Steve, I know it's only been running less than a month and it's too soon to see the long-term profitability, but a decent Expert Advisor (My EA, haha), seems to be able to give you those 20% return a month (so far mine's at 30%), all while you sleep. Under these circumstances I have no problem waiting for that 'full-time' income.
On the other hand, trading other peoples money, would suit me fine, I think it's a question of making it very, very clear to investors, that the possibility they could loose their whole investment is present. It may get you less customers, but they won't (at least I think so) come after you afterwards. In my case, with the 6% a month target, I'd have to say that I won't expect net profits until after the 1st year, because I want to have room for a constant DD of 50%, due to the nature of my strategy. Therefore I need long-term investors that are aware of this. And that's also why I'm reluctant to take on any investors until i have at least that 12 months traderecord.
If net profits is reached earlier, well, that's just a bonus, both for investors and myself 😄.
I have set up a PAMM at Instaforex, with minimum 1$ deposit, and if any investors sign up I'll tell them the above situation before accepting their investment. Because my EA is not older, I've also started with a 10% fee of profits for managing, where most others charge 30-50%.
If my EA is still profitable after 6 months, maybe I'll sign up for an Alpari PAMM, under the same circumstances, knowing that I might never get any customers.
Once I have the funds and the programming skills to move to Dukascopy, that's where my future PAMM will be...
My point is, fulltime trading might not be necessary to get those 20%, and then a 100$ seems to be the perfect investment if you can wait for the steady income.
Cheers, and good luck with your own Expert Advisors.
