Working in the software field I'm aware that beta software can have flaws but if there are critical "showstopper" bugs then it doesn't get released to the public. NDAX apparently has no issue with this. Thanks to their portfolio calculations not updating correctly to accurately reflect trades it has cost me hundreds of dollars due to incorrect information. Having sent in a detailed explanation with screenshots and step by step instructions to their support department in order to bring this bug to their attention (at the very least) I'm left with the question. Support? what support? Day 4 and not even a first reply. Clearly time to be moving platforms
