I am just using the recommended settings and manually adjusting my lot size.
I was having a lot of trouble to until I used an EA to get my GMT offset value.
Just run this once on a separate chart and you will get a pop up window with your GMT offset value.
I did not create this EA, it was pointed out in the forex peace army forums.
Until I fixed that it was not working.
If that does not fix it, then I have no idea what to tell you.
All I know is it's working for me as you can see.
That sound you hear is God laughing as he hears traders say "I know for sure what way the market is going".
