I agree, events like this occur 4 months out of a year, and its possible.
Nevertheless 1k to 10k at a 10 days is possible with 1:200 leverage and accepting ideal setups on atleast 3 currencies i.e gbp/jpy, gbp/chf and GU. This can be trading on 5min and 15min charts.
Personally, I like threads like these. This man is bold enough to post his FXCM statement. I mean, how many of us can say we turned 1K to 126K in a week?
This answer a lot of questions which people have: Would you really make money trading FX? Just how much is possible? etc..
