How do I import tastytrade trades into a journal?
Connect tastytrade from Connections, or download your Transactions history as a CSV, open Import & Export in sizeforzero, choose the account, drop the file and press Import trades. Stock and equity option trades become positions; money movements are left out.
Connect tastytrade
- In sizeforzero, open Connections.
- Choose tastytrade.
- Sign in on tastytrade’s own page. The link is read-only: sizeforzero can see your trades and cannot place one.
- Your fills arrive and then refresh every day.
The CSV path below stays available if you would rather work from a file.
Import a tastytrade Transactions CSV
- In tastytrade, open History, then Transactions, and choose the account and date range you want.
- Download the transactions as a CSV file.
- In sizeforzero, open Import & Export and choose the account to import into.
- Drop the file. Exported from is picked from the file’s columns when sizeforzero can tell; check that it says tastytrade.
- Press Import trades. You are told how many fills landed, how many were skipped as already imported, and anything that needs a second look.
The file is a full transaction ledger. Only rows of the type Trade for stocks and equity options become trades; money movements and everything else are left out.
Stocks and options, not futures
tastytrade also trades futures, and its file lists them alongside everything else. sizeforzero models stocks and single-leg options, so futures and futures options are out of scope. Those rows are left out of the import.
If most of your tastytrade trading is in futures, this journal will not show it. If it is stocks and options, nothing is missing.
The price column and the multiplier
tastytrade’s Average Price already has the contract multiplier applied, so an option filled at 0.45 is written as 45.00 and one at 4.69 as 469.00. Read as it stands, every option would look a hundred times too expensive.
sizeforzero divides the price by the Multiplier column on each row. Shares have a multiplier of 1 and are untouched, and options come out at the premium you actually paid or received.
Options arrive already decomposed
Unlike most brokers, tastytrade writes an option in separate columns: the underlying symbol, the expiration date, the strike price and call or put. Nothing has to be pulled out of a text description, so there is little to go wrong.
The Action column uses BUY_TO_OPEN, SELL_TO_OPEN, BUY_TO_CLOSE and SELL_TO_CLOSE, and quantity is always positive. Those words say what an order did to the position, so a sale that opens a short is journalled as a short and the matching buy covers it. Multi-leg strategies are not tracked as one position.
Expirations and assignments
tastytrade records an expiring option as a Receive Deliver row with the sub-type Expiration, whatever its Action says. sizeforzero closes the open contract at zero on that date. An equity option Assignment closes the contract at zero as an assignment.
The share delivery from the same assignment, a row of the type Receive Deliver for the stock, books the shares at the strike its Average Price states. An exercise row, and any other share delivery, are skipped. The assignment words have not yet been seen in a real tastytrade file, so a row worded differently is flagged with the contract named.
Dates, fees and currency
Dates are written with a time and an offset, for example 2026-01-06T14:35:08+0000, so tastytrade fills keep their time of day. Commissions and Fees are separate columns and arrive as separate figures.
The file has a Currency column, so each row keeps the currency it traded in. Positions can be held in USD, CAD, GBP, EUR, AUD, JPY or CHF, and a fill in any other currency is refused with a plain message instead of being guessed at. Under Show more, an account’s type can be Cash or individual, Margin, TFSA, RRSP, FHSA, RESP, LIRA, or Other or not sure; IRA and Roth have no type of their own.
What the tastytrade import leaves out
Futures, forex and crypto are not supported. A row that is not clearly a trade is flagged for review with a plain reason instead of being guessed at.
sizeforzero never places an order and never moves money. It reads what already happened.
Does sizeforzero sync with tastytrade automatically?
Yes. Connect tastytrade from Connections, sign in on tastytrade’s own page, and fills refresh daily. The link is read-only, and CSV import stays available if you prefer to work from a file.
Does sizeforzero support tastytrade futures?
No. The journal covers stocks and single-leg options. Futures and futures options are out of scope, so those rows are not imported even though they appear in the same file.
Where do I download my tastytrade transactions?
In tastytrade, open History, then Transactions, choose the account and dates, and download the CSV. tastytrade’s support site has the current steps if the menus have moved.
Why does tastytrade’s option price look a hundred times too high?
Because Average Price already has the multiplier applied, so a 0.45 fill prints as 45.00. sizeforzero divides by the Multiplier column, and shares, which have a multiplier of one, are left alone.
How are tastytrade options and strikes read?
From separate columns: underlying symbol, expiration date, strike price and call or put. There is no text to decode, so each contract keeps its strike and expiration exactly as tastytrade states them.
Does the tastytrade import handle short options?
Yes. SELL_TO_OPEN opens a short and BUY_TO_CLOSE covers it. If the short expires, it closes at zero and realises the full premium collected. Multi-leg strategies are not tracked as one position.
What happens on tastytrade assignment?
The option closes at zero as an assignment, and the stock delivery row books the shares at the strike. Exercises are skipped, and a row worded differently from what is expected is flagged with the contract named.
Do tastytrade fills keep their time of day?
Yes. Each row carries a full date, time and offset, so same-day fills are placed in order and your calendar shows the right day.
What happens if I import the same tastytrade file twice?
Nothing is written twice. Every upload is fingerprinted, so a tastytrade download you have already imported adds no trades and says so plainly. Downloads for overlapping periods are safe, and recent imports keep a one-click undo for 24 hours.
Can sizeforzero place trades or move money at tastytrade?
No. It is a journal, not a broker. The tastytrade connection is read-only, and sizeforzero never places an order, holds funds or gives investment advice.
