In plain English
What Resistance means
When price approaches a previous high or another watched area above the market, analysts may call it resistance because earlier buying lost momentum there or sellers became more active. Resistance is normally a zone, not a precise number. A price can briefly trade above it, touch it, or move through it without confirming a lasting change.
Why it matters
Resistance provides a practical reference for interpreting an advance and comparing it with prior price behavior. It can also help explain why a market pauses near a known area. It does not indicate that selling will prevail, and it cannot account for unexpected information or changing market liquidity.
Example
Assume GBP/USD reached 1.2750 on two prior occasions and then declined. When it later rises from 1.2600 toward 1.2750, an analyst may identify approximately 1.2745–1.2755 as resistance. A sustained move above that area could cause the prior resistance to be reassessed.
Quick answers
Common questions
Can resistance become support?+
It can. After price moves above a resistance zone, analysts may watch whether that area supports a later decline into it. The role reversal is possible, not automatic.
Is resistance always a previous high?+
No. Previous highs are one common reference. Analysts may also use moving averages, trend lines, round-number areas, or other technical methods to identify possible resistance.
