okex | A Python client for the Okex API | REST library

I'm currently working on capturing crypto-currency price infos from OKEX. I found that, when a page navigate to https://www.okex.com/trade-spot/eth-usdt, it will initiate a websocket named public and send subscription orders via this websocket. Then, data corresponding sent subscriptions will flow through the same websocket.

My question is, in addition to passively inspecting dataflows in this websocket, is there any way to control it, namely to send subscriptions? If so, can this approch be automated(by puppeteer or something equivalent)?

i have problem to sign api for okex ,in document of okex:

The OK-ACCESS-SIGN header is generated as follows:

Create a prehash string of timestamp + method + requestPath + body (where + represents String concatenation). Prepare the SecretKey. Sign the prehash string with the SecretKey using the HMAC SHA256. Encode the signature in the Base64 format. Example: sign=CryptoJS.enc.Base64.stringify(CryptoJS.HmacSHA256(timestamp + 'GET' + '/users/self/verify', SecretKey))

The timestamp value is the same as the OK-ACCESS-TIMESTAMP header with millisecond format of ISO, e.g. 2020-12-08T09:08:57.715Z.

The request method should be in UPPERCASE: e.g. GET and POST.

The requestPath is the path of requesting an endpoint.

Example: /api/v5/account/balance

The body refers to the String of the request body. It can be omitted if there is no request body (frequently the case for GET requests). method i made fo sign is:

I have a list from a dataframe

print(crypto)

Essentially my goal is to save the output of my def function into a list that I can then save into a data frame. I was working with the function and realized that every time I changed the definition function, it would make the changes to one output at a time. Then I realize that for each output the function is calling itself over and over again. I think I have to call a variable outside of this function that can combine all the calls that the function outputs but I'm not sure how. Updated code with suggestion

I am trying to use ZMQ to connect many publishers to one subscriber (python). This is one such publisher (I use connect instead of bind because the subscriber binds). The code works fine until I unblock the commented code below.

I then receive this error on Windows:

I am working on a indicator which shows the aggregated trading volume of multiple BTC markets.

The indicator works for the most part but for some reason unchecking inputs does not work. Even when everything is unchecked the indicator still plots the aggregated volume of all markets.

It is probably a simple fix but I have no background in coding. I got to this point by looking at other indicators and a bit of trial and error.

I would be very grateful if someone can help me.

I am also thinking it would be very interesting to be able to see what volume came from every single market by plotting the histogram in multiple colors, but I do not think I can pull that off or if it is even possible.

This is the entire code:

I am developing a simple test code using Websocket client using c++ boost. A server I get response from says I need to decompress messages using inflate algorithm. I found out there is deflate option in boost Websocket library but it did not work. Please let me know how to convert data to decompressed string.

What I plan to do

• remove all stop words
• remove all non-words (link and emoji)
• count word number and unique word number

My question: I know how to do this in R (using tidytext), but what is the best practice doing the above in Ruby? I searached around but didn't know any popular related gems.

Thanks to your help

If it's tidytext, the above can be pretty much done as shown below
