Been scratching my head and come up empty

I'm toying with an idea of automatically backing all longshots over a certain price. Anyone got an answer on how to back only say $1.00 or less at BFSP by backing the minimum $5.00 stake and employing another strategy to reduce the stake?

a) It's automated, so I won't know what the price will be or close to.
b) I cannot lay these big prices because until the market goes in play, to try and lay bolters for $4.00 stake would be way too much liability on my bank, considering there will be hundreds of qualifiers a day. Also by automating, I won't know which horses fit the price cutoff.

Quite a conundrum.

It's impossible to watch each race with this method, I'd have to sit there 24 hours a day

Any ideas?
