A Level That Held Before Offers No Promise of Holding Again

[Shadow Trader]

Support and resistance levels are among the most widely used tools in scalping, and one of the most persistent myths surrounding them is that a level which has produced a reaction in the past will produce another. Past reactions are evidence that orders once gathered there, not a commitment from the market.

Levels work through the orders resting around them, such as pending entries, stops and profit targets. Those orders change over time. Once they have been filled, cancelled or replaced, the reason for the earlier reaction may no longer exist. Repeated tests can in fact weaken a level, since each touch consumes some of the orders that defended it.

Context matters as well. A level tested during a quiet session can behave very differently when tested during a data release or a strong trend. Momentum often carries price through a level that held many times before.

A sensible approach treats levels as zones rather than exact lines, and as areas where something may happen rather than where something must happen. The useful question is what the trade plan says if price reacts and what it says if price slices through. A level used with a defined exit in both outcomes serves as a reference point. A level treated as a guarantee becomes a source of avoidable losses.
