Quote from GatorTrader:
what % stop do you use if you want to write the trend, but not get stopped out if the ride isnt straight up? i would use moving avg crossovers to find the trend, but do i always need a stop if riding the trend without being stopped out along the ride up? or a mental stop?
and what market is best for beginners? mini gold, crude, & mini dow?

Of course it's up to you to backtest whatever method you use for following a trend.
The most important thing (!) about trend following is that you must have reentry rules if you get stopped out. Whatever rules you use you will likely get stopped out at some point. If you just walk away you could easily miss a large part of the trend, so you must get back in on the trend ASAP.
