Ethereum API: Implementing Buy and Sell Orders with Profit Only

As an Ethereum developer, you are probably familiar with the concept of buy and sell orders in the Binance API. However, executing buy and sell orders with profit only can be a bit more complicated. In this article, we will explore the logic behind implementing such functionality and provide a step-by-step guide to help you achieve it.

Understanding the Basics

Before diving into the details of implementation, let’s quickly review some essential concepts:

• Execution Types: Binance offers a variety of order types, including market orders, limit orders, stop-loss orders, and more.

• Price Data: You will need to access price data for each asset you wish to trade. Binance provides real-time and delayed price data for APIs.

• API Authentication: Ensure that you have the correct API credentials configured to use the Binance API.

Executing Buy Orders with Profit

If you want to execute buy orders with profit only, follow these steps:

• Get Order Details: Use the GET /orders endpoint to retrieve details of a specific order.

• Check Profit: Check the profit field in the response. If it is non-zero, you are ready to proceed.

• Create a Sell API Request: Execute a buy operation using the POST /orders/{orderId}/executions endpoint with the following parameters:

• “amount”: The number of tokens to buy (e.g. Ether).

• “side”: Set to “buy”.

• “type”: Set to “market”.

• timestamp: Use the timestamp of the API request.

• Define Sell Order: Create a sell action using the following parameters:

• amount: The amount of tokens you want to sell (e.g. Ether).

• bin: Set to sell.

• type: Set to market.

Sample Implementation

Here is an example implementation in Python using the Binance API and the requests library:

import requests









Set API credentials
api_key = "YOUR_API_KEY"
api_secret = "YOUR_API_SECRET"

Set order ID (replace with your actual order ID)
orderID = 123456789

Get order details
response = requests.get(f"
order_details = response.json()
if order_details['profit'] > 0:

Create a sell API request
response_sales = requests.post(
f"
json={
"type": "market",
"side": "sell",
"timestamp": int(time.time()),
"sum": order_details['total']
},
headers={"api_key": api_key, "api_secret": api_secret}
)

Log the API request response
print(response_sell.json())
other:
print ("No profit selling!")

Sample implementation with delayed price data

If you need to implement profit-making buy orders using delayed price data, follow these steps:

• Get order details: Use the GET /orders endpoint with a timestamp set to the current time.

• Check profit: Check the profit field in the response. If it is non-zero, you are ready to proceed.

• Create a Sell API Request: Execute a buy operation using the same parameters as before (“amount”, “page”, and “type”) and a timestamp set to the current time.

Sample implementation with delayed price data

Here is a sample implementation in Python using the Binance API and the “requests library”:

“` python

import requests

Set API credentials

api_key = “YOUR_API_KEY”

api_secret = “YOUR_API_SECRET”

Set order ID (replace with your actual order ID)

orderID = 123456789

Get order details

answer_get_details = requests.get(f”
