Levels where something actually traded

Commodities taught suspicion of old chart levels - the splice manufactures ghosts. Equities deserves a recalibration: a share's chart is one continuous instrument, and its old prices really traded. That honesty is worth something, spent carefully.

Why equity levels carry more memory

• No seams: a share needs no roll and no stitching - the price at any point in history is a price somebody paid for this exact instrument.
• Anchored prints: auction crosses are single prices where the whole market met - the close before results, the open after; heavy-volume days mark prices where large holdings actually changed hands.
• Real position anchoring: holders remember their entry; a price where millions of shares traded is a price where millions of decisions can break even - a mechanism, not just a line.

The honest uses, and the caveat

A level where a name repeatedly found buyers, on volume, is an observation with a mechanism - worth marking, worth watching for behaviour change, never worth trading on its own. And the one structural caveat: corporate actions re-base everything. A split divides every historical price; a large special dividend shifts the series; charts are usually adjusted, which keeps changes true but moves the levels - the equity version, mild but real, of the back-adjustment lesson. Module 8 covers what each action does; the reading habit until then is to check a name's action history before trusting a multi-year level.

Levels against the tiers

Module 1's tiers apply here too: a level in a megacap represents the memory of enormous, diverse participation - durable. The same-looking level in a micro-cap might be one market maker's old quote range - decoration. The chart draws both identically; the tier decides which deserves attention, which is by now this track's standing pattern: every reading tool inherits the liquidity context of the name it reads.
