how to autome trading using a trailing stop

[pwsjames]

Hi
In the training video, 'fully automated hands off trading using a trailer stop',a lay bet is used with a 100 tick margin allowing the trade to go from lay@3 to back @13(drift possibly), with a stop loss of 5 ticks.

My question is this. Is it possible to do the exact opposite.

At the start of the race, is it possible to back first, say at 10(current odds), allow it to go in(hopefully steam in whilst in-play) as much as possible but stop it if it comes back by 5 ticks.
I have noticed a lot of BSP come in by at least 1.5 to over half the odds for quite a few of the runners

Sorry if i am being stupid.

Is it possible to fully automate this so that it could be done first thing in the morning so that i dont have to put the bet in just before the race
I would appreciate any help possible
Many thanks
