I will use Forex when I have to cause either can't get filled in futures or spread too wide in futures, but always I hedge. I been hedging for very long term, and yes there are "tricks" on how to do it, volumes required and when to put on. And yes, I think young traders should stay away and do a great deal of back testing before using hedges. Putting them on wrong just makes for losing worse especially when your basic system for entering currency pairs on directional signals is limited amount of back testing. Your system for entering overall must be profitable first and only then applying hedges can make a good system even better. But the costs are very high if you are entering on trend signals.
There many areas of trading, and I am certainly not at expert level on most of them, just wished there were more hours in a day to study.
