I've been a long time fan of Louise Yamada. Calm, straightforward analysis.

My favorite quote:

this ‘prediction’ thing is not at all about being right. It’s like a road map you look at. If price action supports your analysis, you stick to what your analysis implies. If price action doesn’t confirm what you think should happen, you adapt. That means you re-assess the new situation and you devise a new road map or plan of action
