EA is designed to be used with inverted pairs.
Open one E/$ and one $/Chf chart.
Attach EA to each.
Assign seperate magic number to each.
Select both charts for long only or short only.
Choose account management true or false whichever.
Use the defalt martingale and pipstep for testing's sake.
Or change these settings for more frequent trades. 
Initiate autotrading then notice both charts opening trades after ticks move.
Wait for a secong trade to open when price move against.
Then notice how the trade is then closed at loss.
Then figure out why it is doing this.
The proper function is:
Open two seperate accounts same broker.
Run the same two charts with two longs on one account and and two shorts on the other.
Positions will be opened as pipsteps are inputed. One chart/pair will be in your favor and the other chart/pair will be against. But there will always be some slight hedge for protection. As profit percentages are hit then new positions open.
This is the overall general idea of operation.
But as you will notice, the positions will be limited to just one opening at a time. I have never gone into source code to adjust anything so I'm not sure why it is doing this.
Hopefully you can help. Thank you
