I have compared the Gannanalyst swing charts to my own hand drawn charts and to yours and Robb's on occasions when you have posted. Mostly recently I compared the Gannanalyst swing chart of MQG to yours. There are occasional differences, especially in the treatment of outside days, but basically they are the same. I'm not sure that I understand what you mean when you say they are opposite to yours??
I've posted a chart below of MQG with the Gannanalyst swings for the same time period as your MQG chart. The blue candles are inside and outside days.
