Betangel scalping

Bet angel is one of the bet fair software. Basically what I want is a pre live automation which works for 15 min before a horse race starts. This strategy can analyse the behavior of the market if is going up or down (follow the trend) for just one horse. So if the price (odd) is going down he makes a back bet with 1 trick offset (take profit) and 2 tricks of stop loss. Now here is the point, if the market price (odd) goes up in one trick he places a bet in order to recover the money, this would mean recover the loss, This order should only get triggered if the market goes up 1 trick (negative side). The whole idea is to keep betting continuously during the 15 min of pre live.
