Looking for a simple Scalping trigger

Hi

I am looking for something as described below - can anyone help please?!

*10 mins before a UK horse race - back 1st fav for £2 (customisable amount so can be changed)

*Lay immediately placed for a 20% return on stake (green up book) so in this case 40p

*if not matched after 5mins then the lay changes to 10% return on stake (20p)

*if not matched 10 seconds before the race start then lay @ SP to either green or red up

*STOP LOSS - if price moves -20% of stake the close the bet and take loss


thanks 

Hi
If you want a trigger written exactly to your specification it is best to put in a trigger request.
but you can also adapt one of the scalping triggers available here
and also have a look at the many greening up triggers see if one fits your requirement.
