# Direction Symbols

> Two profiles: Legacy (Unicode) and ASCII. Both parse identically.

| Legacy   | ASCII  | Meaning                         |
| -------- | ------ | ------------------------------- |
| `π:`     | `ID:`  | Identity prefix                 |
| `←`      | `<-`   | Derived from (evidence pointer) |
| `→`      | `=>`   | Transition / becomes            |
| `↑`      | `up`   | Increasing / bullish / rising   |
| `↓`      | `down` | Decreasing / bearish / falling  |
| *(none)* | `EQ`   | Sideways / stable / neutral     |

<Info>In v2.1, → served double duty as "sideways" and "transition." v2.2 splits this: EQ = stable, => = transition.</Info>

**Legacy** (GPT-optimized):

```
π:MED-03|YLD.60|$BTC|from:BEAR→NEUTRAL|RE:OCH-01|NOW
```

**ASCII** (universal):

```
ID:MED-03|YLD.60|$BTC|from:BEAR=>NEUTRAL|RE:OCH-01|NOW
```

A v2.2 parser MUST accept both forms. Both produce identical parse results.
