Support-Resistance Flip (Role Reversal)

One of the more useful ideas in technical analysis is that support and resistance are not fixed lines painted on a chart forever, they can trade places. When a resistance level finally gives way and price closes above it, that same price zone frequently becomes support on the next pullback. The logic is behavioral: traders who missed the breakout are waiting to buy on a dip back to the old ceiling, while traders who sold short into that resistance and got proven wrong now have an incentive to buy back their position near the same area, adding fresh buying pressure exactly where old selling used to sit.

The same flip happens in reverse when support breaks down. A floor that held for weeks or months, once broken, tends to attract sellers on any bounce back up to it. Buyers who bought that support and are now underwater often sell into the retest just to get out near breakeven, and new sellers see the old floor as a logical place to enter short, reinforcing the level as resistance going forward.

A classic example is a stock that bounces off 50 dollars three separate times over a few months. When it finally breaks below 50 and later rallies back up to test it from underneath, that retest at 50 frequently stalls and reverses lower, confirming the flip. Traders who understand this pattern often wait specifically for that retest rather than chasing the initial breakout, since the retest can offer a lower-risk entry with a clear invalidation point just above or below the flipped level.

This concept only works reliably when the original level was genuine, tested multiple times with real reactions, and when the breakout itself showed conviction rather than a thin, low-volume poke through the line. A flip that fails, where price pushes back through the old level without hesitation, is itself useful information and ties directly into the idea of false breakouts covered next.
