How do I fix this code?

   getCandles = (ticker, time, amount) => {
    return new Promise((resolve, reject) => {
        let candles = [];
        try {
            binance.candlesticks(ticker, time, (error, ticks, symbol) => {
                if (error) {
                    reject(error)
                }
                if (ticks.length != null || ticks.length != 0) {
                    ticks.forEach(tick => {
                        candles.push({
                            open: tick[1],
                            high: tick[2],
                            close: tick[4],
                            low: tick[3],
                            volume: tick[5],
                            time: tick[0]
                        })
                    })
                    resolve(candles);
                } else {
                    reject(null)
                }
            }, { limit: amount });
        } catch (e) {
            reject(e)
        }
    })
}

what module are you using generally the function to obtain the candles is called klines, not candlestick, possibly there is your error, I recommend that you read the documentation of the package you are using

Could you please reformat this code, and show us the error message. Even better uploading the code in a repo or as a gist can be helpful to debug :slight_smile:

I have tried posting with correct format but its not displaying as such. If you look at the raw data, its formatted correctly. I did post the code here but never got any response to help me solve this.

The error message is clear enough that binance is not defined here.
Either pass it into this method as parameter, or initialise it here.

how do i pass it into this method? I’ve tried everything I know how to do and keep getting error?

7 
getCandles = (binanceInstance) =>  (ticker, time, amount) => {

// same code
}


// where you call getCandles
getCandles(binance)(ticker, time, amount)

Thank you for taking the time to try to help me fix this… Unfortunately I am still getting an error… It is now saying binanceInstance isn’t defined. If i change that to binance, then i get the candlestick error again…
