# Markets

Starting Price (SP) markets are regular markets where the final odds are unknown at bet time.

### Identify an SP market

Check the `Market.ExtraParameters`.

* `Market.ExtraParameters : { "IsSp": "true" }` for SP markets.

Example:

<pre class="language-json"><code class="lang-json">{
  "extraParameters": {
    "MarketFeatures": "None",
    "ScratchedPositions": "[]",
    "IsExotics": "false",
    "IsFixedExotics": "false",
<strong>    "IsSp": "true"
</strong>  }
}
</code></pre>

### Selections in SP markets

Before the event starts, selection `price`/`startingPrice` is `null`.

You can still receive an indicative price. For example `originalPrice`. Do not treat it as the final SP odds.

Example:

<pre class="language-json"><code class="lang-json">{
  "id": 12345,
  "name": "Goway",
  "probability": 0.39130363,
<strong>  "price": null,
</strong>  "originalPrice": 2.15,
  "status": 0,
  "settlement": 0,
  "deadHeatFactor": 0,
  "extraParameters": {},
  "isBetBuilderSupported": false,
  "competitorId": 54321
<strong>  "startingPrice": null
</strong>}
</code></pre>
