It really depends on the chart.. some of these charts have very thin books.. So when a big order hits there just arent enough buy orders on the bid to handle it for a secons or two and the price drops to fill that one order.. this is not support, because if the guys supporting it had time to react they would have never allowed it to drop that low.. thats why within seconds its back at a more reasonable area.. so support really is where the bigger players wont allow it to go any lower and then you usually get a nice bounce from there.. So most of the long wicks (like the one on BLTZ) dont count..
