reactor: There's a substantial fact to be infered from bobcathy1's post, and that is that BB and Keltner will each give you different prices for your S/R. What's more, different settings for those different indicators will give you different prices. What's more, different time frames for those different settings for those different indicators will give you different prices. Whew. So, in short, S/R is effective so long as a good number of people get active at the same price, which is probably more key than which indicator, or which setting, or which time frame.
