Support and resistance are price areas where buying or selling interest has previously appeared. Traders use them to organise chart observations, but they are not guaranteed turning points and can break or become irrelevant as conditions change.
What do the terms mean?
Support describes an area where a decline has previously slowed or reversed. Resistance describes an area where an advance has previously slowed or reversed. These labels describe past behaviour, not a promise about what happens next.
How can you identify an area?
Review multiple visible reactions in context, note the timeframe and avoid false precision. Different traders may draw slightly different zones because price rarely respects a single exact line. Use a consistent method and record the evidence.
What can go wrong?
A level can break, be crossed temporarily or fail to matter in new market conditions. A screenshot may also omit the history needed to judge a zone. Consider invalidation and risk before treating any area as part of a plan.
