Betfair free API horse racing software

I need a bot written for Betfair that will allow me to trade on the daily horse racing markets and use the free API , so no API fees are desirable but should still have a decent refresh rate on the prices/odds to making trading [login to view URL] bot would need to do the following : I need to be able to select several horses from any race and place these in a ladder, so to [login to view URL] say i want to monitor the price movement of the first 3 horses in the betfair display table, then all i would see is those 3 .I could select as many runners as i wish, though in reality this would be the first 3 or 4 horses only. Next, the bot need to monitor the price movement of EACH horse at the same [login to view URL] notes whether the prices are going up or down a tick depending on what i have selected.I would need a general settings tab to select the parameters of how i wish to trade, notably stakes , the tick movement i wish to monitor ie, if each horse moves an x amount of ticks up or down then this is symbolized by an indicator ie green arrow or whatever when this movement occurs.I would need to make a bet from a one click option on the ladder interface and an automatic opposing bet would be placed at whatever tick less i specify ( if backed ) or above ( if layed ) to lock in a small profit. Example before i monitor the prices i want to be able to select a price movement of anything between 1 tick and say 5 ticks up or down ie, if i select 2 tick movement and the price goes from 2.1 to 2.14 (up ) OR 2.1 to 2.06 ( down ) i need to be able to see this visually by lets say a green arrow pointing up or [login to view URL] if the first 2 horses prices go up by 2 ticks then the bot is configured to show this movement by the arrows and then if ( and only if ) the remaining horse prices of the third horse has taken an opposite trend ie of going down by the same ticks ( or more ) then i can either manually place a bet on the third horse or even better if an automatic bet can be placed and once matched a corresponding opposite bet can be placed to lock in a small profit. The general settings tab will include the trading parameters before the bot starts. I would need a reset button to reset the monitoring at any time, so if i started to monitor the prices for tick movements and then wanted to reset this again the bot would start monitoring the new prices from the time it is reset then check fro any tick movements in accordance with the [login to view URL] it would be a reset/refresh button that would start the monitoring process from the start again. A manual green up button to equalize a profit or loss if it goes wrong is needed. I would need all source at completion also. ONLY THOSE WHO HAVE BETFAIR API EXPERIENCE PLEASE. THANK YOU IN ADVANCE.
