I am not a big fan of some of the Stock Broker’s GUI, so I am attempting at tracking some of my assets on a Google Sheet.
How can I create Manual (click a button) or Automatic triggers, based off of a certain date, to edit a cell's value or add a new entry into a new cell?
Example Triggers:
1) Increment currently owned shares on the Dividend Payout Date.
2) Nightly/Weekly new entries for Profit/Loss for a company/set of companies.
Sample Sudo Logic:
- When TODAY() == 2/2/2018(any variable date saved in a cell), update cell [current shares] with reinvested_shares + current_shares.
- Create a new entry in next available cell with profit/loss for the day. New entry would be static and never changing. This could be a button to manually trigger or automatic.
Since you won't have the spreadsheet that contains the cell information, any sample template (with comments) would be highly appreciated.
