hi
yes this is possible.
i have included a set of triggers for you to use and learn.
in the constants you can set
amount of ticks to green up
amount of ticks to stop loss
maximum back price
minutes before the start time to stop betting
selections rank
option to repeat bets or once per market
bet amount
Also, if I start with 100 pounds in my betfair account, what is a realistic amount I can expect to earn off each race?
the amount of profit is increased by setting the amount of ticks higher for greening,BUT the higher the ticks the more chance of not getting matched for the green up, so this is up to you to learn the best amount for yourself, risk verses profit.
please use test mode until you are happy with your settings
