classifying a trade as buy or sell is a mystery which only few people understands and i am certainly not one of them. All i can see is a trade whether at 0.012 or 1.12 . I can also see x nuber of buyer or sellers at y price and whether at a price buyers or sellers are more.
beyond that is byond me especially when I am sober, may be on a weekend I may be able to come with some iraational logic and call it a buy or sell but on weekdays its just a trade
