I just did some calculation on this system. I think you need to be careful trading this system. If you have you
broker 
offering 1:500
leverage 
then you need $2.00
margin 
to trade 1 micro-lot. If your take profit is 20 pips and open trades every 20 pips that
margin 
requirement can rise to a staggering $4,094

if the market spikes 200 pips without retracing. You will also be down $4,072, so in total if you are 200 pips down you need more than $8,166 in your account.
Now I've been trading this market long enough to know that a 200 spike will come when you least expect it and it most likely not be a scheduled news event.
The only safer option would be to wait for IBFX to open their London office next year. They will
offer 
nanolots and upto 1:500
leverage 
. Forex4you offers nano lots but they are not regulated by the FSA and are located in BVI. No thanks.
