I've solved the x15 algorithm with the right miner i've messed up while moving files.

Hmm,...regarding trademybit prices when I've first launched the app there were no prices, then after a while trademybit x13 price showed up, and then little bit later also trademybit x11,...but no x15 and nist5,....strange.... and i've checked the api url+key manually and get all the prices
