Edo Reaction Zones is a trend and reaction indicator built on a simple idea: moving averages are not exact lines but zones where price tends to react. It wraps five exponential moving averages (9, 20, 50, 100 and 200) in adaptive bands whose width is computed from the ATR, so each zone widens when volatility rises and narrows when the market calms down. Each band turns green when price is above its average, acting as potential support, and red when price is below, acting as potential resistance.
