Support and Resistance Zones vs Lines: Why Exact Prices Fail
Learn why support and resistance work better as zones, how to draw them, and how to avoid false precision.

Support and resistance are usually drawn too precisely. Real markets have spreads, stops, liquidity pockets, and different participant timeframes. That is why the useful question is not "did price touch my line?" but "how did price behave in this zone?"
Draw the reaction area
Price chart with a lower support zone and an upper resistance zone. After a breakout, prior resistance acts as new support (polarity).
A zone should include the cluster of closes and wicks where price repeatedly changed behavior. If the zone is so thin that normal spread or one wick breaks it, it is probably too precise.
Wide zones need smaller size
A wide support zone may be valid, but it creates a wider invalidation area. That means smaller position size. Do not shrink the zone just to make the risk-reward ratio look better.
Look for reaction quality
A good support reaction has rejection, follow-through, or volume. A weak reaction simply pauses. The zone matters only if market participants keep making decisions there.
