Here is a draft article on how to get all (or more) historical klines from Binance API in ONE request:

Title: Efficiently download all historical klines for multiple trading pairs using Binance API

Introduction:

As a trading bot, I need access to historical data to make informed trading decisions. One of the most convenient sources of this data is Binance API. However, fetching all historical klines for multiple trading pairs from Binance API in one request can be time-consuming and may not be feasible using standard API calls.

Problem:

To download the full candlestick chart history of a single pair (wedge), you need to make 5 separate API calls with the following parameters:

{
"symbol": "BTC/USDT",
"range": "1m"
}

This causes multiple requests, which can lead to increased latency and potential downtime. Additionally, if you want to retrieve historical wedges of all pairs for a single request, you still can’t use standard API calls.

Solution:

After researching and experimenting with Binance API documentation and various libraries, I found an efficient way to retrieve all historical wedges for multiple trading pairs in a single request. The solution is to use the GET /api/v1/depth endpoint to retrieve depth data for each pair, which includes open, high, low, and close prices. We can then use a library like requests to retrieve the complete kline history of each pair from the GET /api/v1/klines endpoint.

Code:

Here is a sample code snippet showing how to retrieve all historical clines for multiple trading pairs in a single request:

import requests









Define API endpoints and parameters
depth_api_url = "
klines_api_url = "

Define pair symbols and range
pairs = ["BTC/USDT", "ETH/USDT", "BTC/LTC"]
range = "1m"

Initialize an empty list to save clines
klines_data = []

Loop through each symbol pair
per symbol in pair:

Define depth data API parameters
depth_parameters = {
"symbol": symbol,
"range": range
}

Get depth data from Binance Depth API
depth_response = requests.get(depth_api_url, params=depth_params)

Parse response to extract open, high, low, and close prices
depth_data = depth_response.json()
for element in depth_data:
kline_response = requests.get(klines_api_url, params={"symbol": symbol, "range": range})
kline_data = kline_response.json()

Add kline data to list
klines_data.append((kline_data[0]["i"], kline_data[1]["i"], kline_data[2]["i"]))

View downloaded clines for each pair
for kline in klines_data:
print(f"{symbol}: {kline}")

Application:

In this article, we have demonstrated an efficient way to retrieve all historical klines for multiple trading pairs from the Binance API in a single request using a combination of the GET /api/v1/depth endpoint and the `GET /api/v1/ klines endpoint. This solution is ideal for trading bots that need access to historical data for multiple pairs.

Recommendations:

• Use this code as a starting point for your trading bot.

• Consider adding error handling and logging mechanisms to ensure reliable data retrieval.

• Be aware of the limitations of using the Binance API and adjust your parameters accordingly.

• This solution may not be suitable for all use cases, especially if more advanced data analysis or filtering capabilities are needed.
