[nikspz]

Steps:

1. Cloned and installed feature branch
2. Start the bot instance
3. Check connect, status commands

Actual:

• Gold connectors are Green, Silver are grey and Bronze are Yellow
• Connectors k2, probit_kr (Probit Korea) should be removed since it didn't reach the quorum of 100,000+ HBOT votes
• AWS showed commands painted redon the local client itpainted yellow` when checking status, config and other commands

Is it better to change gold to yellow, silver just silver. or Just dont put colors on it?
Also I think red color on the AWS could mess up the users little bit

[nikspz]

Steps:
Clone and install feature branch
Create docker image manually (docker build -t hummingbot/hummingbot:newcex -f Dockerfile . )
Create/start docker instance

Actual:
At the start bot showed warning message (related to Override Fees files)

traceback:

PR update:

• Text color now displays correct on both source and docker build for WSL, AWS and Mac(m1)
  
• Background color for command has been fixed ✅
• Error on corresponding config has been fixed ✅

However we would like to address that whenever we stop and change exchange, it seems it still displays the previous exchange tier. This would be fix by importing the strategy file again. Crosscheck the behavior on development branch and this only happens on the PR

Paper trade

Spot connector

Perpetual connector

Steps to reproduce:

1. Setup simple PureMM or PerpMM strategy
2. Start the client and notice the prompt about connector status: xxxx...
3. Stop the client and change the connector config exchange
4. Repeat step 4 and notice the prompt that it would display the previous connector tier
5. Try to do Step 3 and add a number of connectors and start the bot again, it should be observe the same results
6. By import command and start the client works as expected
