Ethereum API: Determining the Precision of Futures Assets
As an Ethereum developer, you will likely be 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 determine the precision of a futures asset price 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 obtain the precision of a futures asset price, you need to use the spot_price_precision property. However, this property is only available for spot commodities.
Method:client.get_symbol_info(symbol=’My symbol’)with additional parameters
You can modify theget_symbol_info'' method by adding two new parameters:
- symbol_type
: set to 'futures' to get the exact price information of the futures asset.
Exchange': set to the Binance exchange (e.g.Binance-futures'')
Here is an example:
const client = require('@binance/api');
// Create a new API client instance with
Binance-Futures'' as the exchangeclient.init({
api: {
binanceFutures: {
symbolType: 'future',
exchange: 'financial futures'
}
},
key:
YOUR_API_KEY',secret:
YOUR_API_SECRET''});
// Get information about a specific futures asset
const symbolInfo = await client.get_symbol_info({
symbol: "My symbol",
spot_price_precision: true,
spot_exchange: false, // Optional: set to true for spot markets
spot_exchange_type: 'spot'
});
In this example, we use the client.init'' method to create a new API client instance withBinance-Futures'' as the exchange. We then pass additional parameters to indicate that we want precise information about futures.
Sample response
The response from theget_symbol_info'' method will contain an object with several properties:
symbol'': The name of the symbol.
spot_price_precision'': The precision of the spot market price (e.g. 5).
- "future_price_precision": The precision of the future market price (e.g. 2).
You can access these values using the following code:
Symbol: ${symbol}const { symbol, spotPricePrecision, futurePricePrecision } = await client.get_symbol_info({
//...
});
console.log(
);Spot Price Precision: ${spotPricePrecision}console.log(
);Future Price Precision: ${futurePricePrecision}console.log(
);
Conclusion
Using the `get_symbol_info’ method with additional parameters, you can access the price precision information of 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 replace “YOUR_API_KEY” and “YOUR_API_SECRET” with your actual API credentials. Also, adjust the “token type” and “change” parameters to suit your specific use case.
