Thanks for sharing your experience....@San - Like @BenTen said you need to test what works best for you and your style. I like n @ 21 for 8 tick range bars. Someone else more than likely would use something else. I do not trade minute charts but 21 seems to paint a lot of lines, too many for my taste. I like a clean chart with only key points marked. More is not better from my experience. The best to you.
