UI as so: two textboxes to capture username and password details. button to login to betfair. option to capture mins before race to check for qualifiers (3 options: 1 min, 2 mins, 3+ mins) drop down or radio group. option to capture price move to report on (5 options: 1, 1.5, 2, 2.5, 3+) drop down or radio group option to capure what to report on: (3 options: steamer, drifter, both) drop down or radio group option to capture action to take (3 options: back steamer, lay drifter, back steamers and lay drifters) drop down or radio group The required rules are as so: 1. At one hour PRIOR to a UK horse race going live, the software need to store any selections in that race that fall within the "option to capture mins before race to check for qualifiers" + 5points, so if the "option to capture mins before race to check for qualifiers" is 2, the application records all selections inclusive of the prices 2.00 to 7.00. 2. At "option to capture mins before race to check for qualifiers" the software checks against the stored selections at rule 1: If "option to capure what to report on" is "steamer" or 'both" and the price of the selection has REDUCED <= "option to capture price move to report on" and option to "capture action to take" is "back steamer" or "back steamers and lay drifters": present simple screen to place BACK BET as per standard place bet functionality at betfair. If "option to capure what to report on" is "drifter" or 'both" and the price of the selection has INCREASED >= "option to capture price move to report on" and option to "capture action to take" is "lay drifter" or "back steamers and lay drifters": present simple screen to place LAY BET as per standard place bet functionality at betfair. Standard validation is required - i.e check and report invalid betfair credentials, etc I have the code for this application, but it is written in VB.NET, I basically need it converting to objective-c as I don't know the language, don't have the time or desire to learn it!
