Lay shortly before the off, then tick offset in-running

[montague]

I'm new to BA but very, very impressed.

I have an existing betting model that I have to run manually, but I want to automate it through BA if possible. Basically, I identify races where I want to place a lay bet a minute or two before the off at the prevailing price (let's assume it's a favourite trading at 2.0). I don't want to enter the market earlier in the day because of market fluctuations, non-runners, etc. As soon as my lay is traded just before the off, I want to back the same horse and keep the bet in-running for a level profit across all runners (via the great 'tick offset' and 'auto level' feature in BA). Let's assume I choose a tick offset back price of 2.5. I am working on the belief that the favourite will drift to at least 2.5 during the running of the race.

Can anyone advise me how I could automate this through BA? I presume I'll need to do it via Excel scripting but don't have the necessary knowledge. I understand that the BA software will need to be running all day until the race takes place (while I'm at work). The key thing is knowing how to set up a lay that doesn't take place until a minute or two before the scheduled 'off' time of the race.

I hope some of you BA experts can point me in the right direction. I will typically be placing two or three lay bets a day using this model.

Cheers,

Montague
