How is it that I went from 2% max draw down to 28.8% max draw down over night whilve my position is still open and is down just about half a percent total .50 even with my stop loss that is set there is no chance of there being a large drawdown like especially off of one trade. How are they calculating drawdown

Hi, Dan - We had a problem with our quotes last night. I will remove the erroneous data point shortly if it is related.
