# Code Examples

## Code examples

The fastest way to see every SDK call in action is the [reference console app](https://console.trading-sdk.symm.io/). It consumes `@symmio/trading-core` and `@symmio/trading-react` exactly the way a third-party integrator would, and drives real contract reads and writes, deposits, quotes, and positions:

* Live console: <https://console.trading-sdk.symm.io>
* Source (monorepo): <https://github.com/SYMM-IO/Trading-SDK>
* UI component explorer (Storybook): <https://symmio-frontier-storybook.vercel.app>

### Minimal headless bot (end-to-end)

A single-file bot that sets up once, opens one position, and sketches how to manage and close it. It uses `@symmio/trading-core` and `@symmio/session-key`, and assumes the SubAccount was already created (see Part 1).

```typescript
import {
  createConfig, SymmioSupportedChainId,
  getUserSubAccounts, grantDelegation, getIsDelegationActive,
  INSTANT_TRADE_REQUIRED_SELECTORS,
  getMarkets, watchEnigmaPrices,
  instantOpenAuto, instantCloseAuto, setQuoteTpSl, PositionType,
} from "@symmio/trading-core";
import { createSessionKeyManager } from "@symmio/session-key";
import { createPublicClient, http } from "viem";

const OWNER = "0xYourOwnerEOA";

const publicClient = createPublicClient({ transport: http("https://rpc.hyperliquid.xyz/evm") });

const config = createConfig({
  symmioConfig: {
    [SymmioSupportedChainId.HYPER_EVM]: { addresses: { affiliatesAddress: "0xYourAffiliate" } },
  },
  defaultChainId: SymmioSupportedChainId.HYPER_EVM,
  getClient: () => publicClient,
  getWalletClient: async ({ chainId, from }) => resolveWalletClient({ chainId, from }),
});

async function main() {
  const [subAccount] = await getUserSubAccounts(config, { user: OWNER });

  const manager = createSessionKeyManager({ storage });
  const { address: sessionKey } = await manager.initialize(OWNER);

  await grantDelegation(config, {
    account: { addr: subAccount, isPartyB: false },
    delegatedSigner: sessionKey,
    selectors: INSTANT_TRADE_REQUIRED_SELECTORS, // three selectors: open, add margin, close
    expiryTimestamp: 1_766_000_000n,
  });

  // getIsDelegationActive checks one selector at a time; all must be true
  const checks = await Promise.all(
    INSTANT_TRADE_REQUIRED_SELECTORS.map((selector) =>
      getIsDelegationActive(config, {
        account: { addr: subAccount, isPartyB: false },
        delegate: sessionKey,
        selector,
      })
    )
  );
  if (!checks.every(Boolean)) throw new Error("delegation not active");

  const symbols = await getMarkets(config, {});
  const symbol = symbols[0];
  const market = { id: symbol.symbol_id, name: symbol.name };

  watchEnigmaPrices(config, { onPrices: (ticks) => {/* feed your strategy */} });

  const { tempQuoteId } = await instantOpenAuto(config, {
    from: sessionKey, subAccountAddress: subAccount,
    market, positionType: PositionType.LONG,
    initialMargin: "100", leverage: 5, slippage: 1,
  });
  console.log("opened, temp id:", tempQuoteId);

  // Resolve the on-chain quoteId from watchNotifications/reconcileQuotes,
  // and the position's Virtual Account from resolveQuoteAccounts, then:
  // await setQuoteTpSl(config, {
  //   from: sessionKey, quoteId, virtualAccount, subAccount,
  //   symbolId: market.id, positionType: PositionType.LONG,
  //   quantity: "0.01", pricePrecision: symbol.price_precision,
  //   tp: { triggerPrice: "150", priceType: "markPrice" },
  // });
  // await instantCloseAuto(config, {
  //   from: sessionKey, partyA: virtualAccount, market,   // partyA is the VA
  //   positionType: PositionType.LONG, quoteId, quantityToClose: "1", slippage: 1,
  // });
}

main().catch(console.error);
```

> This is illustrative scaffolding, not a strategy. Add error handling (core throws `SymmError` / `SymmApiError`; the React layer normalizes everything to `SymmioRequestError`), reconnection for the price and notification sockets, and your own risk logic before running with real funds.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.symm.io/trader-documentation/building-a-trading-bot/code-examples.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
