Ethereum: CCXT Binance fetchohlcv does not return the latest data
As an avid enthusiast and cryptocurrency merchant, you are probably not strange to the decentralized world (Dexs) as Binance. When it comes to tracking and analyzing price movements in cryptocurrencies such as Ethereum, access to high quality historical data is crucial for informed investment decisions.
In this article, we will plunge into a common problem that many users find when using the CCXT library on Binance: seeking OHLCV (open, ups, low, closed) via FetchlCV does not return the latest historical data.
The problem
When you use fetchohlcv to recover historical data from Ethereum NET, it is essentially obtaining a instant price movements at a specific time. However, Binance is known to update your OHLCV diet periodically to ensure that they remain accurate and updated.
Unfortunately, the CCXT Library in Binance does not seem to be receiving these updates, causing it to return outdated data. This can lead to inaccurate predictions of future price movements or incorrect identification of trends reversal.
The solution
To solve this problem, you have some options:
1.
Make sure your binance API key has the correct settings
Make sure the Binance API key is correctly set on CCXT. You can do this by following these steps:
- Login on your binance account and go to
settingts>API.
- Make sure your API key is activated for CCXT.
- Check the
timeoutconfiguration and make sure it is not defined too low as this can cause CCXT to be the limit time while looking for data.
2.
Instead of using the standard fettohlcv end point, try to use the alternative terminal provided by Binance: https: // api.binance.com/API/v3/ohlcv.
To do this, you can modify your CCXT configuration as so:
JavaScript
Consta CCXT = Requires (‘CCXT’);
Const Binance = new ccxt.binance ({
// your API key and secret
});
binance.fettohlcv ({symbol: ‘eth’}, (error, result) => {
if (error) {
console.error (error);
} other {
CONST LASTDATA = Result.last;
// process the data as needed …
}
});
`
3.
Use a latest version of CCXT
Make sure you are using a recently released version of the CCXT library as it is possible that a bug or correction has been implemented to solve this problem.
To check if there are updates, visit the [CCXT website] ( and select the latest version. Then compare your current version with what you are currently using.
Conclusion
In conclusion, looking for OHLCV data via fetthohlcv at Binance CCXT library can sometimes return outdated or incorrect historical data. To solve this problem, make sure your API key is correctly set and try to use a different fetchohcn end point. If the problem persists, consider updating to a newer version of CCXT.
