I see that you want me to write an article on how to get multiple market streams (e.g. user data streams and Websocket market streams) from the Binance Futures API into a single stream.
Here is the article:
Getting Multiple Market Streams into a Single Stream
The Binance Futures API allows developers to access various types of market data, including user-defined data streams and websocket-based market streams. However, accessing multiple data streams simultaneously can be difficult due to limitations imposed by the API design.
In this article, we will examine whether it is possible to receive user data streams and Websocket Market Streams into a single stream using the Binance Futures API.
Accessing User Data Streams
User data streams allow users to collect specific market data points. These streams are typically used for advanced trading strategies that require real-time data streams. To access user data streams, you need to send a “GET /trades/user-data” request with your API key and access token.
Accessing Websocket Market Streams
Websocket Market Streams provide real-time market data over Websocket connections. These streams are also used for advanced trading strategies that require real-time data streams. To access Websocket Market Streams, you need to send a “GET /trades/websocket” request with your API key and access token.
Combining User Data Streams and Websocket Market Streams
While it is technically possible to combine user data streams and Websocket Market Streams into a single stream using the Binance Futures API, this approach has some limitations. According to the documentation, you can only subscribe to separate streams for each data source, which means you need to send two separate requests: one for the user data stream and one for the Websocket Market Stream.
Here is an example of how you can combine two into one stream:
`spam
GET /trades/user-data?ids=1&fields=id,name,price,open,high,low,close,volume HTTP/1.1
Host: binnace.futures-api.com
Content-Type: application/json
{
"ID": [
1
],
"fields": [
"id",
"name",
"price",
"open",
"high",
"low",
"close",
"volume"
]
}
spamGET /trades/websocket?ids=1&fields=id,name,price,open,high,low,close,volume HTTP/1.1
Host: binnace.futures-api.com
Content-Type: application/json
{
"ID": [
1
],
"fields": [
"id",
"name",
"price",
"open",
"high",
"low",
"close",
"volume"
]
}
However, this method would result in two separate streams: one for user data streams and one for Websocket Market streams. You can then combine these streams using the “union” function provided by the Binance Futures API.
Using the union function
To combine two streams, you need to use the “union” function, which allows you to combine multiple streams into one. However, this function is only supported by a limited set of data sources, so multiple requests must be sent with the same “ids” parameter.
Here is an example of how user data streams and web socket market streams can be combined using a join function:
spam
GET /trades/user-data?ids=1&fields=id,name,price,open,high,low,close,volume HTTP/1.1
Host: binnace.futures-api.com
{
"ID": [
1
],
"fields": [
"id",
"name",
"price",
"open",
"high",
"low",
"close",
"volume"
]
}
GET /trades/websocket?ids=1&fields=id,name,price,open,high,low,close,volume HTTP/1.1
Host: binnace.futures-api.com
{
"ID": [
1
],
"fields": [
"id",
"name",
"price",
"open",
"high",
"low",
"close",
"volume"
]
}
