FAQ
What is Logbook for Alpaca?
Logbook for Alpaca is a read-only client that analyzes your trading activity on Alpaca. It calculates the true cost of your trades, identifies unfilled orders, and itemizes all fees to provide a net figure that reconciles with your balance.
How does Logbook calculate trade results?
Logbook pairs your buy and sell orders on a first-in, first-out basis per symbol, using Alpaca's position intent. This ensures that each trade shows what it rode on and what it returned, providing a correct win or loss calculation.
Does Logbook show orders that never filled?
Yes, Logbook lists orders that were submitted, accepted, and then expired without ever trading. It separates these from filled orders, highlighting potential losses from open positions that did not exit as planned.
How does Logbook handle fees?
Logbook fetches and itemizes all SEC, FINRA, and CAT fees under the day they belong to. It then shows a net figure that reconciles with your balance, providing a more accurate picture of your trading profitability than order data alone.
What information is available in the 'Book' section of Logbook?
The 'Book' section provides an overview of your equity, cash, buying power, and every open position with its size and return. This gives you a comprehensive snapshot of your current account status.
Is Logbook secure with my API keys?
Yes, API keys are verified once against Alpaca and then stored securely in your device's Keychain. There is no Logbook account, no server of ours, and nothing is transmitted anywhere except to Alpaca's API under your own credentials.
What are the pricing details for Logbook?
Logbook is free for three days, offering full access to all features. After the trial period, a single one-off purchase unlocks the app permanently, with no subscription required.
What devices does Logbook support?
Logbook is supported on iPhone and iPad devices. It also offers a Home Screen widget for quick access to equity, the day's change, and outstanding orders.
