# `zfin history`

Two modes in one command, selected by whether you pass a symbol.

```
Usage:
  zfin history <SYMBOL>     # last 30 days of candles
  zfin history [flags]      # portfolio-value timeline
```

## Symbol mode

With a positional symbol, shows the last 30 trading days of OHLCV
candles:

```bash
ZFIN_HOME=examples/pre-retirement-both zfin history VTI
```

```
Price History for VTI (last 30 days)
========================================
        Date       Open       High        Low      Close       Volume
2026-06-04       370.62     373.99     370.36     373.38    3,111,996
...
```

## Portfolio mode

With no symbol, reads your `history/*-portfolio.srf` snapshots and
renders rolling-window returns, a braille chart, and a recent-snapshots
table. (Build that history with [`snapshot`](snapshot.md).)

| Flag                  | Effect                                          |
|-----------------------|-------------------------------------------------|
| `--since <DATE>`      | Earliest as-of date (inclusive).                |
| `--until <DATE>`      | Latest as-of date (inclusive).                  |
| `--metric <name>`     | `liquid` (default), `illiquid`, or `net_worth`. |
| `--resolution <name>` | `daily` \| `weekly` \| `monthly` \| `auto`.     |
| `--limit <N>`         | Cap the recent-snapshots table (default 40).    |
| `--rebuild-rollup`    | Regenerate `history/rollup.srf` and exit.       |

Dates accept `YYYY-MM-DD` or relative shortcuts (`1W`/`1M`/`1Q`/`1Y`).

```bash
ZFIN_HOME=examples/post-retirement zfin history --metric net_worth --since 1Y
```
