Track Every Assignment Without Losing the Thread
Getting assigned is not the end of a trade — it is the middle of one. QuantLog links the assigned option to the resulting stock position so your cost basis, break-even and realized P&L follow the full cycle.
Assigned puts become linked stock
When a short put is assigned, QuantLog creates the resulting share position and ties it to the original option. The premium you collected lowers your effective cost basis automatically, so the number you see is what you actually paid.
Called-away shares close the loop
Sell covered calls on those shares and get called away, and the sale closes the same trade group. Total realized P&L includes the put premium, every call premium, dividends received and the final share sale — one number for the whole cycle.
Expirations, exercises and early assignment
Worthless expirations, exercises, early assignment before a dividend and cash settlement on index options each get their own handling, so no leg is silently marked as a full-profit expiration when it was really a loss.
See how often assignment actually happens
Analytics show how many positions ended in assignment, how those trades performed against the ones that expired, and what your average cost basis reduction looks like across the wheel.
Assignment tracking — FAQ
Does the premium reduce my cost basis?
Yes. The credit collected on the assigned option is applied to the resulting stock position, so break-even reflects the real entry price.
What about dividends while I hold the shares?
Dividends can be linked to the open position and are included in the cycle's realized P&L.
Are index options ever assigned?
No. SPX, XSP and NDX are cash-settled, and QuantLog records the settlement value instead of creating a share position.
