ThetaQuill
From statement to insight

Five minutes to your
first real insight.

No setup wizards. No data-provider keys to find. Just upload your broker CSV and ThetaQuill does the rest.

1

Sign up free

Username + password. No credit card. No email verification needed for the free tier. You're in the app in under 30 seconds.

2

Create your accounts

Add each brokerage account you trade — taxable, Roth, traditional IRA, 401(k). Name them however you want. Set a starting balance for each.

3

Import a broker CSV

Export your trade history from Schwab, Fidelity, IBKR, Webull, or E*TRADE. Drag the file into ThetaQuill. We auto-detect the broker, pair multi-leg fills, and flag duplicates.

4

Review your insights

Within seconds you'll see your win rate, profit factor, drawdown, strategy breakdown, and which days of the week actually make you money.

Then the loop kicks in

The real value isn't the first import — it's the weekly review that compounds your edge.

5

Trade

Trade your normal week. Add notes to each setup — what you saw, why you took it. Two seconds per trade.

6

Review

Friday afternoon: open Insights. Which strategy made money? Which one bled? Look at the worst 5 trades — what's the pattern?

7

Adjust

Cut the strategies that aren't working. Double down on the ones that are. Your journal becomes your edge.

8

Repeat

Every Friday. Forever. This is what separates traders who blow up from traders who compound.

What it does behind the scenes

Encryption-on-write

Every trade you log is encrypted before it hits the database. A stolen DB dump is unreadable without the server key.

Smart deduplication

Re-import the same CSV next week? ThetaQuill recognizes every existing trade by content hash, only adds the new ones.

Cent-perfect math

Pro-rated fees, fractional-share precision, multi-lot FIFO matching. Your balance matches your broker's penny for penny.

Tax-aware

Trades in Roth/IRA accounts are excluded from capital-gains calculations automatically. Capital losses cap at $3k with carryover.

Try the loop

First 50 trades a month are free forever.
