// Setup & Preferences
Accounts, Currency, Fees, and P&L Settings
A handful of settings quietly reshape every number you see. Two in particular — the base currency and the option P&L basis — are display choices that change nothing stored.
Most settings do what their label says. Two are worth reading properly, because they change every number on the screen while changing nothing that is stored: the base currency and the option P&L basis.
// 01 · accounts
Multiple accounts
Each account tracks its trades, positions, and results independently, so a brokerage account and a retirement account never blend into one number. You can keep three; the Add account button disappears when you reach the limit.
Settings that read “Account Preferences” on the settings page belong to whichever account is active at the time — switch accounts and the values switch with them.
The account picker at the top of the app decides what every page shows, and imports land in whichever account is selected. There is also an all-accounts overview, which groups by currency and totals nothing across a currency boundary — for the same reason the setting below applies no conversion.
// 02 · display
Base currency
This chooses the symbol every amount is displayed with. No conversion is applied. If you record a trade in one currency and switch the display to another, the number is unchanged and only its symbol moves.

Timezone
Your timezone places trades on the time-of-day and weekday charts and on candlestick markers. It is auto-detected from your browser and can be changed.
It does not rewrite the times on your trades, and it doesn’t move anything on the P&L calendar — a trade keeps the wall clock it was recorded with. Chart sections that read hours offer a toggle between your local time and US market time.
// 04 · lots
Cost basis method
When you sell part of a stock position, this decides which shares you sold — and therefore what each sale realized.
| Method | Which shares a sale uses |
|---|---|
| Average Cost | Every share carries the position's weighted average price, so a partial sale realizes the same per-share result whichever shares left. |
| First In, First Out (FIFO) | The shares you bought earliest are sold first. The convention most brokers report by. |
| Last In, First Out (LIFO) | The shares you bought most recently are sold first. |
Changing the method changes nothing on its own. The setting has to be saved, and existing sells keep the result they were recorded with until you press Recalculate All Trades, which recomputes the realized result of every sell in the account under the new method. The button is offered only when the method you picked differs from the one in use.
// 05 · the big one
Option P&L % basis
Every option percentage has to divide by something, and there are two defensible choices. This setting picks which.
| Basis | Divides by | Reads as |
|---|---|---|
| Collateral | What the position tied up. | Return on the capital the trade actually required. |
| Trade ROI | The premium collected at open. | How much of the premium you kept. |
The choice applies across the options tracker, the dashboard, and trade notes at once, so the same trade never reads two ways in two places. It’s a display choice: no stored result changes, and switching back restores the previous percentages exactly.
// 06 · commissions
Default commissions
Separate defaults exist for options (per contract) and stocks (per trade). They pre-fill the commission when you enter a trade by hand, and stay editable on every one.
// 07 · positions
Position locking
When on, a position locks once fully sold, and rebuying the same ticker starts a new position instead of reopening the old one — which keeps each round trip’s result separate. Turning it off lets the old position reopen and absorb the new shares.
This is per account. The full explanation, including the different lock you hit when shares back a covered call, is in grouping trades into one position.
Short selling
Also per account, and off until you switch it on — see how to short sell and cover.
// 08 · risk
Deployed-capital warning
Warn when deployed exceeds (%) sets a threshold on how much of the account’s balance is tied up — option collateral plus the cost of open stock lots, divided by the balance. It is a number between 1 and 100, and it is per account.
Crossing it changes nothing about your trades. It marks the deployed figure on the dashboard, draws the threshold on the Risk History chart, and drives that page’s count of days spent at or above the line.
