At ikofx, I think 0.2 lot equal to around 0.2 cents per pip. With leverage of 500:1, the margin to buy 2000 units of GBPUSD is around $6 (I think). So, yes, it's possible.
At the top of this page it says leverage is 1:0 which I doubt it, since his main page doesn't show leverage status. Plus, what's 1:0 leverage?
