Ethereum API: Getting Price Precision for Futures Assets
As an Ethereum developer, you are probably working with the Binance API to access various cryptocurrency markets. In this article, we will explore how to use the get_symbol_info method to get the price precision of a futures asset on Binance.
Method: client.get_symbol_info(symbol='My symbol')
The get_symbol_info method returns information about a specific symbol, including its:
- Symbol name
- Symbol type (spot or future)
- Exchange (e.g. Binance)
To get the price precision of a futures asset, you need to use the spot_price_precision property. However, this property is only available for spot markets.
Method: client.get_symbol_info(symbol='My symbol') with additional parameters
You can modify the get_symbol_info method by adding two new parameters:
symbol_type: Set to `future'to get price accuracy information for futures assets.
exchange: Set to Binance exchange (e.g. `binance-futures')
Here is an example:
const client = require('@binance/api');
// Create a new instance of the Binance-Futures exchange API client
client.init({
api: {
binanceFutures: {
Symbol type: 'future',
exchange: binance-futures
}
},
key: 'YOUR_API_KEY',
secret: 'YOUR_API_SECRET'
});
// Get information about a specific futures asset
const symbolInfo = wait client.get_symbol_info({
symbol: 'My symbol',
spot_price_accuracy: true,
spot_exchange: false, // Optional: Set to true for spot markets
spot_exchange_type: 'spot'
});
In this example, we use the client.initmethod to create a new instance of the Binance-Futures exchange API client. We then pass in additional parameters to specify that we want price accuracy information for futures assets.
Sample response
The response from theget_symbol_infomethod will contain an object with several properties:
- symbol
: The name of the symbol.
- spot_price_precision
: The spot market price accuracy (e.g. 5).
- Future_priceprecision: The future market price accuracy (e.g. 2).
You can access these values using the following code:
Symbol: ${symbol}const { symbol, spotPricePrecision, futurePricePrecision } = wait client.get_symbol_info({
//...
});
console.log(
);Spot PriceAccuracy: ${spotPriceAccuracy}console.log(
);FuturePriceAccuracy: ${futurePriceAccuracy}console.log(
);
Conclusion
Using the get_symbol_infomethod with additional parameters will give you access to price accuracy information for futures assets on Binance. This will help you work with more precise and accurate price data in your cryptocurrency trading applications.
Note: Be sure to replaceYOUR_API_KEYandYOUR_API_SECRETwith your actual API credentials. Additionally, adjust thesymbol_typeandexchange` parameters according to your specific use case.
