Ethereum: CCXT binance fetch_ohlcv function

Here is an article that explains why you are getting errors when using fetch_ohlcv () at binance API with CCXT:

Ethereum: Looking for Binance API OHLCV data with CCXT

When working with cryptocurrency markets, such as Ethereum, it is essential to recover real -time data to make informed negotiation decisions. Fortunately, we have tools like CCXT (Cryptocurrency Trade Watchtower) and Binance API that provide easy access to market data.

However, there are several reasons why fetch_ohlcv () may not be working correctly when using the Binance API with CCXT. In this article, we will explore what is going wrong and provide a solution.

Why fetch_ohlcv () is problematic

Before we dive into the subject, let’s quickly cover because fetch_ohlcv () can be a challenge:

* API rate limits : Binance API has rate limits to avoid abuse. When you make a lot of requests in a short time, your API key or access token can be revoked.

* Data format differences : Binance and CCXT market data may require different formatting, which fetch_ohlcv () does not support by default.

Solution: Using the ccxt.binance.fetch

method

Instead of using fetch_ohlcv (), you can take advantage of the ccxt.binance.fetch method to search OHLCV (OHLCV) data from the Binance API. See how to use it:

`JavaScript

Consta CCXT = Requires (‘CCXT’);

// Create a binance customer instance

Const Binanceclient = new ccxt.binance ({

Symbol: ‘BTCUSDT’,

Options: {

Enableratelimit: True,

Activated: False, // Define this as True if you are making more than 50 requests per second

Ratelimit: {

Delay: 60, // Seconds

Period: ‘1m’, // minutes

Type: ‘IPS’

}

}

});

// Search OHLCV data using fetch_ohlcv ()

binanceclient.fetch (‘ohlcv’, [‘btcussdt’], (err, result) => {

if (err) console.error (ERR);

// process the data

Consta ohlcvdata = Result;

console.log (ohlcvdata);

});

`

Additional Tips

• Make sure you have an active binance account and a valid access token.

• Define enableratelimit as false if the API key or the rate limit is not being revoked.

• You can adjust the options ‘Delay’, Period andType 'in the Object' Options to adjust the data search process.

In conclusion, when using the Binance API with CCXT, fetch_ohlcv () may not work as expected due to rate limits or format differences. By leveraging the ccxt.binance.fetch method, you can recover Binance’s API OHLCV data without finding errors. Happy commerce!
