# Stream live state

For live positions and orders, open a WebSocket instead of polling. The server pushes a full snapshot on connect, re-pushes it whenever the basket changes on-chain, and sends lightweight metric ticks in between.

## Connect

```
wss://flashapi.trade/owner/{owner}/ws?updateIntervalMs=1000
```

`updateIntervalMs` sets the metric-tick cadence (default `1000`, min `100`, max `10000`).

## Handle the two message types

```javascript
const ws = new WebSocket(`wss://flashapi.trade/owner/${owner}/ws?updateIntervalMs=1000`);

ws.onmessage = (ev) => {
  const msg = JSON.parse(ev.data);
  if (msg.type === "basket") {
    // Full snapshot: positionMetrics / orderMetrics keyed by market pubkey,
    // plus raw basketData (base64). Sent on connect and on every basket change.
    render(msg.data.positionMetrics, msg.data.orderMetrics);
  } else if (msg.type === "metrics") {
    // Metrics-only tick: positionMetrics keyed by market pubkey. Refresh PnL/liq.
    updateMetrics(msg.data);
  }
};
```

* `basket` — full state; the first message is always a `basket`, so you have bytes before any tick.
* `metrics` — position metrics only, on the oracle-tick cadence, so PnL/leverage/liq keep refreshing cheaply.

The server pings every 30s and closes the socket if no pong arrives within 10s. You don't need to send anything after connecting.

## Limits

Max **5 connections per owner** and **10,000 global** — `429` and `503` respectively.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.flash.trade/flash-trade/flash-trade-protocol/build-on-flash/flash-trade-v2/guides/stream-live-state.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
