Here is an example of an article explaining the problem:

Ethereum: “code” and “message” issue when creating futures order on Binance CCTX

As an Ethereum developer, you are probably familiar with trading on cryptocurrency exchanges such as Binance. In this article, we will look at a common problem that arises when trying to create simple futures orders on the CCTX (Coincheck Trade) exchange using the ccxt library for Ethereum.

Code and Configuration

Here is a code example demonstrating how to create a CCTX futures order using ccxt:

import ccxt
exchange = ccxt.binance({
'apiKey': config.api_key,
'apiSecret': config.api_secret,
})









Determine the contract and symbol for Ethereum
contract = exchange.getContract('ethusd', 'USDT')
symbol = 'USD/ETH'

Determine the future order
future = {
'type': 'future',
'symbol': symbol,
'side': 'buy',
'timeInForce': 'gtc',
'expiration': '2024-03-01T23:59:00Z', 
expiration date and time
'quantity': 10.0, 
amount of ETH to trade
}

Creation futures order
result = exchange.createOrder(future)
print(result)

Problem

Now that we have the code configured, let’s resolve the “code” and “msg” issue mentioned in the error message.

In ccxt, when creating a futures order, you can specify the code field as an integer. However, the problem arises if this code does not match the expected code provided by the contract (CCTX in this case). If the code does not match, ccxt will return an error message in the following format:

{"error": {"msg": "The order position does not match the user setting."}}

Solution

To solve this problem, it is necessary to make sure that the code field corresponds to the expected code provided by the contract. In this case, the CCTX contract uses a different symbol (for example, ETHUSDT) than the one we specified in our future object.

One possible solution is to use the symbol and contractSymbol parameters provided by ccxt when creating a futures order:

Definition of a futures order
future = {
'type': 'future',
'symbol': symbol, 
replace with the actual CCTX contract symbol
'contractSymbol': 'ETHUSDT', 
replace with the actual CCTX contract symbol
'side': 'buy',
'timeInForce': 'gtc',
'expiration': '2024-03-01T23:59:00Z', 
expiration date and time
'quantity': 10.0, 
amount of ETH to trade
}

By using the symbol parameter, we can ensure that the code field corresponds to the expected code provided by the contract.

Usage Example

To demonstrate this solution in practice, let’s update our sample code:

import ccxt
exchange = ccxt.binance({
'apiKey': config.api_key,
'apiSecret': config.api_secret,
})

Define the CCTX contract symbol and exchange settings
contractSymbol = 'ETHUSDT'
exchange.symbol = contractSymbol

Determine the future order
future = {
'type': 'future',
'symbol': contractSymbol, 
replace with actual CCTX contract symbol
'side': 'buy',
'timeInForce': 'gtc',
'expiration': '2024-03-01T23:59:00Z', 
expiration date and time
'quantity': 10.0, 
amount of ETH to trade
}

Creation of futures order
result = exchange.createOrder(future)
print(result)

With this updated code, we should no longer receive the “code” and “msg” error message when creating a CCTX Binance futures order using ccxt.

Hope this helps! Let me know if you have any additional questions or if there is anything else I can help with.
