Understanding range highs and lows are all you need. #stocksBack on October 27th I made a post highlighting a potential reversal as we approached the range lows from back in June. Over the future months the stock tested the lows, found support, and is not heading toward highs. Range highs and lows and major support and resistance areas have value because they indicate where there is likely to be heavy order flow. In this case it AMGN reacted well and held the lows creating a great risk/reward opportunity.
