I don't do hedging because it's just confusing. If you believe that your initial position is with the major trend, then you should stick with it because sooner or later, price will do a quick snap back towards the direction of the major trend. however, I have also experienced cases where price can go against you for some time even though your trade is with the major trend.
What I do is averaging my trade. For example, if I am caught in a change of major trend, and price is going against me without an opportunity to reverse, I will wait for an opportunity (at possible retracement points) to open a new contract that is 3-5x the size of the initial contract. I will wait for the price to perform the retracement I was expecting, and get out at BE.
eg. Long EURO. Down by 40pips. Enter 3-5x contract, wait for minor retracement (upwards) to take place. Get out with BE.
