Trading

Example code snippets to stream from the indexer for trading automation module related data using StreamManagerV2.

Note: IndexerGrpcTradingStreamV2 returns raw protobuf responses without transformation.

Using gRPC Stream with StreamManagerV2

Stream grid strategies

import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { 
  StreamManagerV2,
  IndexerGrpcTradingStreamV2 
} from '@injectivelabs/sdk-ts/client/indexer'

const endpoints = getNetworkEndpoints(Network.Testnet)
const stream = new IndexerGrpcTradingStreamV2(endpoints.indexer)

const streamManager = new StreamManagerV2({
  id: 'trading-grid-strategies',
  streamFactory: () => stream.streamGridStrategies({ 
    marketId: '0x...', // optional, but either marketId or accountAddresses required
    accountAddresses: ['inj...'], // optional array
    callback: (response) => {
      streamManager.emit('data', response)
    }
  }),
  onData: (gridStrategies) => {
    console.log(gridStrategies)
  },
  retryConfig: { enabled: true }
})

streamManager.on('connect', () => console.log('Stream connected'))
streamManager.start()
