{quote} The trend is not a friend to grid systems. ~30% time market is trendy and ~70% ranged. The problem is nobody could tell when trend starts/ends. You can observe only post factum that it already started or ended.

I think the market is trendy and ranging when you define it as trendy or ranging. It is whatever you define it. Everyone has a different understanding of trend. I figure it's just all about risk management and being consistent in your strategy with a trading journal.
