Trading with market structure

How much importance do you give to market structure?

A chart can have several indicators showing different signals, but higher highs, lower lows, and important swing points can provide a clearer picture of price direction.

I'm interested in how other traders identify a change in market structure.

Do you wait for a break of structure, a retest, or a confirmation from another timeframe before entering? I'd like to hear how you avoid false breakouts.
