Blik, yes that does suck, maybe next time... I really enjoyed the challenge as well. I would like to figure out some method to make a more generic platform that doesnt take so much effort to keep updated - e.g. automatically updating prices would help alot, then a platform where we can create challenges, set how many shares and expiry dates. Maybe we can work on something like that. I just need to find the data providers, so far i didnt have any luck, they wanted to charge me so much money that it wouldnt make any sense. I guess if we can organise something with the data we could create a very interesting platform... I dont know if any of you have more details on how one could get data, end of day is perfect, end of week would also do, that can be programatically sucked into a website's database that doesnt cost lots or can be arranged as a sponsor? One could create advertising for such type of entities and open the site to anyone who wants to create a challenge.
