Betfair trading software

Hi, Looking for a simple trading software to trade selected horses at a set time before the off and to trade out either before the off or during inplay for a set percentage or £ amount. For example we can produce a number of horses/selections during the race day which we believe will trade higher or lower during inplay, i.e we believe after making an initial back selection at 10 minutes before the off at odds of 10.0 the horse will eventually trade lower at approximately 8.0 or below, the bot would trade out if our target profit is achieved, the opposite will also be required for a horse we believe will rise in price. The bot will need to have options of the following which can be altered before the days activation i.e:- Target profit per trade i.e £1 Max exposure per trade selection Min market volume before initial trade entry Max/Min odds the horse will use at initial trade entry A list would be genertaed by the bot with all selection for the day, a check box will be next to the horse to signify whether the initial trade should be a back bet i.e we believe price will reduce or an initial lay bet if we believe price will rise. Would be a bonus if it could trade below the £2 minimum for testing purposes. I'm after someone who is experienced and can make minor adjustment if required within the agreed price.
