Easy way to automate single trade

[woohoojd]

I want to automate a trade. Very simple. I want to lay at 4.00. If the odds ever go above 4.30 I want to back and green out and take an equal profit across all selections (but if they shoot from 4.00 to 6.00 then I don't want to simply be accepting 4.30 - I hope this makes sense)! If odds go below, say 2.00, I want to 'red out' and take an equal loss across all selections.

Can I use a stop loss and set it as the ticks from 4.00 to 2.00? When I use stop losses they always seem to leave me with a larger loss on one selection then the others so I still need to be present and manually 'red out' - am I correct in thinking this is how they operate or am I doing something wrong.

Also if I use an offset, it would simply take the bet at 4.30 rather than getting me the 6.00 I could achieve - again I hope this makes sense.

Note - the initial lay is pre-off but the subsequent bets are in-play.
