Unit 7 of 10 · Intermediate

Compression and expansion

In one read

A squeeze is compression: price coils into a tightening range as buyers and sellers reach a standoff and volatility falls. A breakout is the expansion that follows, when price leaves the range on a burst of range and volume. The two are one cycle. Reading it means telling a real breakout from a fakeout: the genuine move holds beyond the range's edge and carries volume, while the fakeout pokes out and snaps back inside. Compression tells you energy is building; it never tells you which direction the release will take. This unit walks the cycle on a generic session — the coil, the expansion, and the give-back — then hands you a real volatility session you can run and recompute, so the shape stops being folklore and becomes a receipt you can check.

Compression and expansion are one cycle

Markets alternate between two states. In compression, price coils into a tightening range: each swing is smaller than the last, volatility falls, and buyers and sellers settle into a standoff. In expansion, that balance breaks — price leaves the range on a burst of range and volume, and the quiet becomes a move.

A squeeze is the compression phase; a breakout is the expansion that follows. They are not two separate events but two halves of one cycle, and the whole skill of reading them is knowing which half you are in.

A worked example

Take a generic broad-ETF session — call the instrument GENCO. Early on, the candles shrink: narrow bodies, overlapping ranges, a coil. That is the squeeze, and it tells you energy is building. It does not tell you which way the release will go — compression is direction-blind.

Then the coil releases. Price pushes past the range's edge; the candles grow; volume steps up. That is the expansion. The test that separates a real breakout from a fakeout is simple to state: a genuine move holds beyond the edge and carries volume behind it, while a fakeout pokes out and snaps back inside the range within a candle or two. Later in the same session the move gives some of it back — expansion is not a straight line, and the give-back is part of the shape.

See it in kestrel

Read the cycle off a real recorded session instead of taking anyone's word for the shape:

npx kestrel.markets sim s-p-500-etf-pandemic-volatility-crash

That runs a deterministic simulation over a generic broad-ETF session with a genuine compression-then-expansion sequence — managed licensed data, no wall time, no signup, no card — and prints a certified proof URL. Recompute the whole record on your own machine, byte for byte:

npx kestrel.markets certify https://kestrel.markets/proof/art_66d7dda7f0466f69c123463c

Keep the tool one command away: drop the kestrel.markets MCP server into your client, and the next session you want to read is already wired up.
