Need get actual order list. How?

[lesni4ok]

Great simple code. I am not so familar with websocket, threading, etc , but strongly need actual order list for fantastic HTF scalping and have similar bot on bitmex.
This code is very simple and beautiful, but without actual order list feature useless for me (
If I right understand , i need this functional:

1. take full order list from REST API
2. do separate infinite loop on orders change channel, maybe at separate thread
3. modify local order list with events from orders change channel
   Not trivial task for me, unfortunally ((
   Maybe anybody, who can do this easy, can help me with this big trouble
