Forex has been discussed here many times before. And I think you are new to this. There are many people here already doing these things. There are many companies in Pakistan that offer to trade forex on you behalf (sort of like a fund).
I don't think you know what you're talking about. If you put in USD 5,000, you can't lose USD 5,500. Brokers at retail level don't allow that. Maybe if you are a very big institution, and put up significant assets in collateral, your broker might be willing to give you more room to play with.
On regular retail accounts, if you put in 5,000 and they have margin call at 70%, that means you can never have more than USD3,500 worth of positions in the market including the commissions/premiums etc. If you go above USD 3,500 on existing trades, they close your trades and you are left with USD 1,500. If you try to place orders worth more than USD 3,500 in the first place, they tell you you don't have enough money to place orders.
Also, most real/proper/regulated brokers don't allow you to withdraw anything unless all trades are closed. So if you have say USD 5,000 in your account with NO active positions in market, you have every right to withdraw all of it. If your broker isn't allowing that, your broker is an obvious scam.
And by the way this "olympusfx" is a scam. Try to get your money out of it before it's too late. You mentioned you have USD10k with them. And I don't think you made enough in 6 months of work with the group to do that. Instead your "employer" convinced you to put up your own money in olympus and you did. That's where your group makes money (they get paid very heavy commissions on clients they bring in, clients such as you). You effectively paid your own salary. Also, those withdrawals that you made must have been very small withdrawals, you just took out the profits that you made, right? Try to get all of it out, and see what happens.
