Store Ethereum Futures in Testnet: APierror (reduced order is rejected) despite successful implementation via Binance Web API

As a blockchain enthusiast, it is not uncommon for users to experience several commercial and API platforms. We have recently found a frustrating problem with the Futures Ethereum in Binance Testnet using the "Python-Binance" library in Python.

background

The "Python-Binance" library is the official integration of the popular Binance API interface that makes it easy to access developers to access and replace cryptocurrencies, including Ethereum. The library provides a convenient way of performing operations through its web interface or using the user interface for more intuitive interfaces.

TESTNET FUTURES COMERCIO via Binance Web API

In order to use the future Testnet business function at Binance, we must first create an account with binance and generate the necessary API keys. Once the logo we get access to the API web interface using a secure connection (HTTPS).

From the "Python-Binance" documentation we can operate operations through the following final points:

• Post/API/V3/Trade: Commercial Futures Treaties

Post/API/V5/Mercado Order Book *: Get current market prices and provide contract information

problem

After configuring our Testnet account and API keys, we try to start an order to "buy short" (only reduced) using the "Python-Binance" library. Unfortunately, despite successful ordering through the user interface in coverage mode, we find a mistake when we try to do it through the API web interface.

An error message suggests that "Reduction order is rejected". This suggests that Binance's internal validation mechanisms have rejected our commercial application for some reason, even if we could successfully perform it through the user interface.

Curs and solution

In order to clean this problem, we will look in more detail at the code of the code provided by the Python-Vinance library. After the exam, we found that the final point of the testnet futures meeting is not designed to "reduce" that are intended to purchase or sell a contract.

To solve this problem, we decided to explore alternative approaches using IU and other API offered by Binance. We create a coverage account and try to make our store through the coverage interface in coverage mode.

After some experimentation with different types of orders and parameters, we could successfully make an "short purchase" order (reduced) through the coverage interface. This solution suggests that the use of the user interface could be a viable alternative for Futures trading in Binanka Testnet, despite the restrictions of the stored Binance API final points.

Conclusion

This article emphasizes an unexpected problem with the "short purchase" order (only reduced) in the Binance testnet network via the "Python-Binance" library. However, it also shows how to experiment with API and alternative interfaces can provide solutions for common problems.

For users who are interested in exploring the Ethereum futures shop at Testnet Binance using the "Python-Binance" library, this article provides a valuable lesson: always check the final points and API documentation before trying comprehensive operations.
