# Build a strategy

> Use the Miramarket strategy builder to create a valid strategy.

This workflow applies to humans using the canvas and AI agents reasoning about the same structure.

## Choose a starting point

Start with either a condition or an action.

Choose a condition when the strategy should wait before committing capital.

Choose an action when the strategy should allocate capital immediately.

## Add actions

Actions represent what the strategy can do with capital.

Common actions include:

* Buy a market outcome.
* Sell a market outcome.
* Hold a market position.
* Move capital to a wallet.
* Move capital to a vault.

Each market action should include a market, outcome, and token ID in the exported strategy JSON.

## Add conditions

Conditions watch signals and decide when actions become eligible.

Use conditions for:

* Price thresholds.
* Time-based triggers.
* Return or PnL thresholds.
* Resolution timing.
* Multi-clause `AND` logic.

## Create a decision group

Place one condition and its eligible actions in the same decision group.

For one selected action, use `SINGLE`.

For multiple selected actions, use `SPLIT_100` and set every action's `allocation_pct`.

Example split:

| Action    | `allocation_pct` |
| --------- | ---------------: |
| Buy `YES` |             `60` |
| Hold      |             `40` |

The total must equal `100`.

## Continue after an action

Add a child condition after an action when the strategy should continue after that action runs.

In strategy JSON, this continuation is an edge from the action to the next condition.

Do not connect a condition directly to another condition. Do not connect an action directly to another action.

## Set risk guards

Market actions can include optional risk guards.

| Field                    | Meaning                                      |
| ------------------------ | -------------------------------------------- |
| `min_edge_bps`           | Minimum expected edge in basis points.       |
| `max_spread_bps`         | Maximum acceptable spread in basis points.   |
| `max_slippage_bps`       | Maximum acceptable slippage in basis points. |
| `max_data_staleness_sec` | Maximum age of market data in seconds.       |

Risk guards help prevent execution when market conditions no longer match the strategy design.

## Validate before export

Validation catches structural errors before you rely on a strategy.

Fix every validation error before treating strategy JSON as ready.
