Ethereum: How to Speed Up Binance Coin Price Parsing

=================================================================

As you’re creating a bot that places multiple orders on Binance, it’s essential to optimize your code for fast and reliable coin price parsing. In this article, we’ll explore the best practices to speed up the parsing process.

1. Use the async/await Syntax

The provided code snippet uses the Async Sub syntax, which is not recommended for CPU-intensive operations like price parsing. Instead, use the async/await syntax to write asynchronous code that’s easier to read and maintain.

Private Async Sub Timer1_Tick()

    Dim price as decimal

    Do Await PriceParse() // await the parse operation

    price = await ParsePriceAsync()

End Sub

2. Use a Task instead of a Thread

In .NET, threads are not recommended for high-performance tasks like price parsing. Instead, use Tasks to run asynchronous operations in the background.

Private Task TaskParsePrice() As Task


Sub Initialize()

    TaskParsePrice = new Task.TryParsePriceAsync()

End Sub


Task ParsePriceAsync() As Decimal

3. Use a Strongly-typed Language

VB.NET is not strongly-typed, which can lead to performance issues due to the need for runtime type checking. Consider using C

or other strongly-typed languages like JavaScript or Python.

public class PriceParserTask : Task

{

    private readonly IAsyncDisposable priceParser;


    public PriceParserTask(IAsyncDisposable priceParser)

    {

        this.priceParser = priceParser;

    }


    protected override async ValueTask FinishAsync()

    {

        return await priceParser.ParsePriceAsync();

    }

}

4. Use a Library with Optimized Parsing

There are libraries available that optimize the parsing process, such as ethers.js and binance-async-parser. These libraries use advanced techniques like memoization and caching to improve performance.

const ethers = require('ethers');

const Parser = require('./parser');


async function PriceParse() {

    const parser = new Parser();

    const price = await parser.ParsePriceAsync();

    return price;

}

5. Use a CPU-GUARANTEED API

If performance is still critical, consider using a CPU-guaranteed API like binance-api or binance-cpp. These APIs are optimized for high-performance and provide a strong guarantee on their functionality.

import binance.client


api = BinanceClient()

price = api.get_price(symbol="BTCUSD", unit="USD")

By following these best practices, you should be able to significantly improve the performance of your coin price parsing. Remember to test your code thoroughly in a production environment before deploying it to live markets.

Example Use Case

—————

Here’s an updated example that combines the async/await syntax and a library like ethers.js for optimized parsing:

Private Async Sub Timer1_Tick()

    Dim price as decimal

    Task.TryParsePriceAsync Try.Catch =>

        await PriceParseAsync(price) // use Task.TryParsePriceAsync to parse price asynchronously


    price = await ParsePriceAsync() // use ParsePriceAsync to parse price synchronously

End Sub


Private Function PriceParseAsync(price As Decimal) As Task

    Dim parser = new Ethers.Parser

    Return parser.ParsePriceAsync(price)

End Function

Note: Replace Ethers.Parser with the actual library you’re using for parsing.
