All subscription methods return an Unsubscribe function that can be used to cancel subscriptions: 
unsubscribe, err := client.Stream.SubscribeTokenCandles(&api.SubscribeTokenCandlesRequest{
    Chain:        "sol",
    TokenAddress: "6p6xgHyF7AeE6TZkSmFsko444wqoP15icUSqi2jfGiPN",
    Resolution:   "1m",
    Callback: func(candle *api.TokenCandle) {
        log.Printf("New candle: %+v", candle)
    },
})
if err != nil {
    log.Fatal(err)
}

// Cancel subscription
unsubscribe()

​
Batch Subscription

Batch subscribe to multiple data streams

​
Usage Example

unsubscribes, err := client.Stream.BatchSubscribe(func() []func() {
    return []func(){
        func() {
            client.Stream.SubscribeWalletBalance(&api.SubscribeWalletBalanceRequest{
                Chain:         "sol",
                WalletAddress: "wallet address 1",
                Callback: func(data []*api.WalletBalance) {
                    // todo
                },
            })
        },
        
        func() {
            client.Stream.SubscribeWalletBalance(&api.SubscribeWalletBalanceRequest{
                Chain:         "sol",
                WalletAddress: "wallet address 2",
                Callback: func(data []*api.WalletBalance) {
                    // todo
                },
            })
        },
    }
})
if err != nil {
    log.Fatal(err)
}

// Cancel all subscriptions
for _, unsubscribe := range unsubscribes {
    unsubscribe()
}
