I think we at nearly there, this is exactly what I want. Just one thing, would it be possible to write into this trigger a rule where you lay first and then it's gets you out of the market by backing, at the moment it just backs and then lays.
Sorry for messing you about but this is the first trigger I have asked to be written so I am very new to this.
I appreciate all the hard work you have done with this and how frustrated you must be with me.
Thanks again.
