Date: 10 November 2021.
Start Time: 08:00 AST (12:00 UTC)
Duration: 2-4 Hours (Just to be safe)

Reason
Overtime we have grown and also the software has grown. We are processing more and more data, configs are getting bigger, more users are sending TradingView signals. This means that the machines we are using need to be able of handling this amount of traffic. This is not always the case.

There is never a good time for maintenance as crypto never sleeps, so I picked a time that fits me best.

What will be affected during down time?

1. License server will be down

• running bots will be able to keep doing their things
• bots cannot start if they shutdown
• Users on 2.5 will be able to safe their ACTIVE config. (Since we store it locally now temporarily)
• You will not be able to create new configs

2. Signals will not be processed

• During this time some if not all signals might not reach your bots.
• Handle your positions accordingly. turn on SOM if you need to.
• Prevent opening new positions, pay close attention to positions
