Help with automating with excel

[Pedromole]

I am after a bit of advice ..... as someone who has only traded on the ladder interface and manually traded in running I am completely ignorant of interfacing with excel and automating things with BA.

Sometimes at the moment I manually select races in which I am interested. I wait for the race to go 'in play' and then lay the entire field at say 1.2 so that any runners that drop to this level are picked up. Hardly a new idea and one which lots of people follow. However, The whole manual process is a little tedious and it seems to me that it could be automated.
So my question is: Can I get BA to automatically switch to the next race in my pick list as soon as it goes 'in play' and then trigger bets into the market from excel? Important point is that I want it to fire in fairly quickly for all runners after the race starts to ensure that I am near the front of the queue rather than wait for the price to begin trading before the bet fires, I only want to lay each runner once and I want to keep all the other bets live so that if more than one runner drops to that price then it is picked up as well.

Is this possible? And how the heck do I do it? I have looked at the sample spreadsheets including the 'trigger betting' one but to be honest I am a little out of my depth.

Any advice gratefully received.
Cheers

I thought there was a function in BA itself to Lay the field. If you don't want to hit a button to do it, there is a trigger called LAYFIELD from Excel to do it.
