As a passionate enthusiastic of cryptocurrency and the merchant, you probably are not strange in the world of decentralized exchanges (Dex) as Binance. When it comes to monitoring and analyzing cryptocurrency price movements such as Ethereum, having access to high quality historical data is crucial to make informed investment decisions.
In this article, we will immerse ourselves in a common problem that many users comply when they use the CCXT library in Binance: to recover the OHLCV (open, ups and downs) data through FOBTOHLCV does not return the latest historical data.
The problem
When you use fetchohlcv to recover historical data for Ethereum mainnet, you are essentially receiving a pricing snapshot at a specific time. However, it is known that Binance periodically updates your OHLCV foods to make sure they remain precise and updated.
Unfortunately, the CCXT library in Binance does not seem to receive these updates, which causes the return of obsolete data. This can lead to inaccurate forecasts for future price movements or incorrect identification of modern investments.

- Make sure the API key is enabled for CCXT.
- Verify the

2.
Use a different fetchohlcv end
Instead of using the predefined final pointfetchohlcv, try to use the alternative end point provided by Binance: https: // bees.binance.com/bees/v3/ohlcv.
To do this, you can change your CCXT configuration in this way:
JavaScript
Const ccxt = requirements ('ccxt');
Const binance = new ccxt.binance ({{
// Your API key and the secret
});
binance.fothohlcv ({symbol: 'eth'}, (error, result) => {
If (error) {
Console.error (error);
} other {
Constt lastdata = result.last;
// Process data as necessary ...
}
});
3.
Use a more recent version of CCXT
Be sure to use a recently released version of the CCXT Library, since it is possible that an error or correction has been implemented to treat this problem.
To verify the updates, visit the [CCXT website] ( and select the latest version. Compare your current version with what you are currently using.
