If you use this ea I would recommend using 4 SL and 1 TP. Starting lot should be .01. If you want to use the percentage high risk would be 50%. It goes up .01 every odd hundred at 50%. Such as 300 is .02 then 500 is .03 and so on. Fridays have killed this EA almost everytime so far. Mondays are 50/50. Tuesday, Wed, and Thurs do very well. I've used E/U and G/U. Every other pair I've tried has too many losses. I'm currently playing with the trailing but it doesn't work the way I want it to so I don't use it.
