A lot of traders will set a price they will stop their losses at...in other words, those who bought .63's the other day may say, if .59 breaks down, I will sell at loss to keep my losses at a minimum...I believe .58 was a major stop loss trigger on BAA...I see it the opposite, I see it as a major buy opportunity on the fear of others...usually they do these type of "sweeps" just before a big move to shake out weak hands & get shares cheaper before the move...I hope this helps, feel free to ask questions as you have them...Good luck!
