How levels flip: support becomes resistance · Reading Charts: Price Action from Zero

One of the most reliable things on a chart is that a broken level changes sides. Old resistance becomes new support. Old support becomes new resistance. This is not a rule of thumb; it follows directly from the trapped-trader logic of Lesson 1. Once you see why, you will see it everywhere.

Breakout and retest. Price stalls under the same level several times, pushes above it, then drops back to touch it from above before carrying on. That touch is the retest, where the old ceiling is tried as a floor. A break that falls straight back under it is a false breakout.

The mechanism

Take a resistance level at 60. Buyers have been rejected there three times. Then one day price breaks through and closes at 62.

Three groups now exist:

Traders who shorted at 60 expecting a fourth rejection. They are losing. If price comes back to 60, they will buy to cover, relieved to get out flat.
Traders who bought the breakout at 60.50 to 62. They are winning. If price pulls back to 60, some will add to their position at what they now consider a discount.
Traders who missed the breakout and wanted in. They are waiting for a pullback. Many have picked 60 as the price to buy.

All three groups buy at 60. The level that used to be a ceiling is now a floor.

 Before the break: 60 is resistance

  60 ---|---------|----------|----------
        |         |          |
      +---+     +---+      +---+
      |   |     |   |      |   |
    +---+ |   +---+ |    +---+ |
          +---+     +---+      +---+

 After the break and retest: 60 is support

                                          +---+
                                        +---+ |
                            +---+     +---+
                          +---+ |   +---+
                        +---+   +---+  <- retest of 60, buyers show up
  60 ------------------|---+-------|--------------
                     +---+
                   +---+

The mirror case works the same way. Support at 40 breaks, price closes at 38. Traders who bought at 40 are trapped and will sell if price rallies back to 40. Traders who shorted the break will add. Traders who missed the break will short the pullback. The old floor is now a ceiling.

Why the retest matters

The flip is confirmed on the retest, not on the break. Plenty of breaks fail: price closes above 60, then falls straight back below and traps the breakout buyers instead. The retest is where you find out which story is true. If price returns to 60 and buyers show up (small wicks below, a close back above, momentum resuming), the flip is real. If price returns to 60 and slices through, the break was false and the original resistance is still in charge.

This is why "breakout and retest" is the first setup in Module 7. The retest is a moment where you can see, in one or two candles, whether the new side of the level is holding.

Key idea: When a level breaks, the traders who defended it become trapped, and the traders who traded the break want to add on a pullback. Both groups place orders at the old level from the other side. That is why resistance becomes support and support becomes resistance. The retest is where you confirm it.

A worked example in numbers

Day	Open	High	Low	Close	Event
1	58.0	60.1	57.6	58.4	Rejected at 60 (third time)
2	58.5	59.8	58.0	59.5	Approaching again
3	59.6	62.3	59.4	62.0	Break: closes well above 60
4	62.0	62.8	61.0	61.3	Pause, small red
5	61.2	61.5	59.9	60.8	Retest: wick to 59.9, close above 60
6	60.9	63.5	60.7	63.2	Buyers resume; flip confirmed

Day 5 is the whole lesson. Price came back to the old resistance, dipped a few cents below it, and closed above. The shorts from day 1 covered, the breakout buyers added, the latecomers got in. Day 6 was the result.

Now compare a failed version:

Day	Open	High	Low	Close	Event
3	59.6	62.3	59.4	62.0	Break
4	62.0	62.2	60.4	60.6	Sharp give-back
5	60.5	60.9	58.7	58.9	Slices through 60, closes below

Same break, different retest. On this version the breakout buyers from day 3 are now the trapped group, and 60 is back to being resistance, arguably stronger than before because a fresh crowd just lost money there.

What "flip" does not mean

It does not mean the level is now permanent. Flipped levels get consumed like any other. It does not mean every break flips; some breaks run so hard that price never comes back to retest, and some fail immediately. And it does not mean you can enter blind on the first touch of the old level. You still want to see the reaction: the wick, the close, the follow-through.

It also does not require exactness. The retest may stop 30 cents above the old level, or poke 40 cents below it. It is a zone. What matters is that price arrived near the level and the new side showed up.

Try it: Find a clean breakout on a daily chart, a close above a level that had rejected price at least twice. Scroll forward. Did price come back to the level? What did the retest candle look like? Then find a break that failed and compare. Keep both examples; they are the two halves of Module 7's first setup.

Recap

When a level breaks, its defenders are trapped and its breakers want to add. Both place orders at the old level from the new side, so the level flips.
Resistance becomes support after an upside break; support becomes resistance after a downside break.
The flip is confirmed by the retest, not the break. A retest that holds confirms; a retest that slices through means the break failed.
A failed break traps a new crowd and can make the original level stronger.
Flipped levels are zones and get consumed over time like any other level.
