Personally I LOVE taking the other side of head-andshoulders set ups. I usually place stop order to get LONG and create a new position in these situations. I know most people use stop order to close out a position that is losing, but I do the opposite.
Once the index has breached a point where it should not go (the right hand shoulder) I have a stop order to get long there. Everyone is expecting the market to decline, so going through that number creates a massive short squeeze to the upside that is like a crash in reverse.
