Quote from illiquid:
Trendfollowing will usually work when there is a trend, and will likely fail when there isn't one. To me it's like asking if being long works better than being short.

Quote from spike500:
There is ALWAYS a trend, but you have to look in the right timeframe.
It is not the same as asking if being long works better than being short. Because to know if long is better than short you need to know the trend. If the trend is short, short is better than long; if the trend is long, long is better than short. It's as simple and logic as that.
