Description

tastypl is a Go program that imports your tastyworks transactions and figures out some statistics to help you track your performance and positions. The main motivation behind it was to track the net credit after rolls.

Demo

On the tastyworks desktop app, go to the History tab, and under "transactions" pick a start date that is before the creation of your account, then click the CSV button to export all the transactions to a file. You need all the transactions in the CSV file otherwise the numbers won't make sense.

Here is a simple example for a portfolio with an AAPL straddle, a BIDU position that has received an assignment, and a ROKU position that has been rolled.

$ go run tastypl.go -input demo.csv -printpl -positions

The -chart option will generate a graph in rpl.png that looks like this:

On the chart, "adjusted realized P/L" is the realized P/L net of commissions, fees, interest paid if any, etc. Outstanding premium is the amount of premium sold (if positive, bought if negative) at the price it was opened – the script does not track the mark of positions over time, only opening/closing prices, as it does not have access to any historical market data. Cash on hand should match what is shown in tastyworks' account balance.
