tastypl

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.

It has since evolved to provide a lot of accounting data that TastyWorks simply does not provide.

NOTE: This repository is a fork of the orginal at https://github.com/gotasty/tastypl which has not been maintained in a while.

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
----- Overall statistics ----

---- Realized P&L detail ----
/NQH8    80.00
BIDU   1148.00
PCLN    896.00
ROKU    122.00
----- Current portfolio -----
AAPL  (2 positions)
  Feb 16 short 1 $170 call @ 7.2 [BEP=177.20] 
  Feb 16 short 1 $170 put  @ 5.35 [BEP=164.65] 
  --> 170 straddle @ 12.55 net credit
BIDU  (3 positions) [RPL=1148.00]
  long  100 shares @ 250.00 (adj. cost basis 247.66)
  Feb 16 short 1 $217.5 call @ 7.4 [BEP=224.90] 
  Mar 16 short 1 $250 put  @ 32 [BEP=218.00] 
ROKU  (1 position) [RPL=122.00]
  Feb 16 short 1 $44 put  @ 4.78 [BEP=38.00]  (net credit 6.00)

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.

Daily Balances

The -daily option will generate a CSV output with daily balances (something tastyworks is lacking). You should run tastypl with the -daily option by itself and redirect to a file to get a CSV file.

The following fictional sample has had the rows and columns transposed to make it easier to the see the (almost 4 dozen!) output fields.
