I am (slowly) working on a daily P&L tracker to track my day to day trading. Currently the tracker is up and available for free. Just please understand that this is a work in progress!
Current features:
- Waterfall style chart by day.
- Calendar view with weekly totals.
- TOS paste position adding (copy order from inside of Think or Swim).
- Accordion Table View (expand / collapse).
- User association is via Google Authentication API. Only used to map the data you add to your user.
- It automatically calculates expired vertical results once the close for the day is in.
- Note: This currently only works with SPX and mostly just verticals. ;-) but hey its free and its a WIP.

Let me know if you end up using it! Or if you find any bugs or features you would like added.
