There are many activities which get refreshed at midnight and if you're interested in Min/Maxing profit should be done each day.
This is the list of activities which I do in order of priority each day.
- Complete Daily Tasks
- Procurement for Shops
- Claim Stolen Cash (if you do)
- Claim Login Price (if you have access)
- International Trade
- Operations (for Luxuries, then Traits)
- Joint Promotions
- Contribute to Guild (I do a minimum of 1 million daily)
- Vote for Sectoral Interests Senate
- PvE (coordinate this with your guild, it gets much better)
- WTC Campaign
Have fun, ST
