Dale,
Yes that was their mistake, intentionally or unintentionally misled us, I don’t know, but I give them the benefit of the doubt 
As for the hedge strategy, by no mean is Risk Free, all trading systems, no matter how aggressive or conservative, have some weaknesses and involve risk more or less. Traders have to learn and adopt to market condition. There is no way we can just sit back and collect profit risk free, that is NOT true.
For those who read this thread. Do not rely on any opinion, but think for yourself, test it out, if you think it work, use it, if not, move on to any other method that you think more profitable.
Good trading,
