This idea has been mentioned in a number of previous posts. The idea is that as an alternative to entering a buy/sell/short order as a price, it could be entered as a price relative to the feed. The advantages in being able to do this could be that orders do not need to keep getting monitored and shifted around as BTSX moves around, which also incurs new fees, and it might be easier for market-makers to set a spread relative to the feed price. Maybe the idea has been superseded by a better approach to solve these problems, or maybe the technical difficulties are the problem? In any case, I was wondering what the status is.
