# Marketlab v0.1.91 (/changelog/v0.1.91)



## Three New Strategies [#three-new-strategies]

* **[POV](/strategies/pov)**: size orders as a percentage of live traded volume.
* **[Iceberg](/strategies/iceberg)**: work one smaller limit slice at a time.
* **[Scale](/strategies/scale)**: place a ladder of limit orders across a price range.

```bash
mlab strategy run scale BTC --venue bulkf --testnet \
  --side buy --size 0.01 --start-price 78000 \
  --end-price 80000 --levels 5 --duration 900 --dry-run
```

Example prices. `--dry-run` previews the orders; replace it with `--yes` to submit.

In **Furge**, open **Strategies**, choose a strategy, enter the inputs and preview. The terminal's **Execution → Strategies** menu carries the selected market into the form.

Runs report submitted and filled amounts and attempt to cancel their remaining orders when stopped or expired. A duration does not guarantee a full fill.

## Upgrade [#upgrade]

```bash
mlab upgrade
```

This release updates the daemon protocol. Restart your daemon after upgrading. Managed deployments must update both the CLI and daemon image to v0.1.91.
