Connecting Alpaca to a Portfolio Tracker: What Actually Syncs

Connecting Alpaca to a portfolio tracker pulls your live positions, quantities, and cost basis into one dashboard through a read-only API key. This guide explains exactly what syncs automatically, what Alpaca does not report (especially crypto cost basis), and how to fix missing purchase prices so your gains and losses actually add up.

What does connecting Alpaca to a portfolio tracker actually do?

Connecting Alpaca to a portfolio tracker links your brokerage account through the Alpaca Trading API, which streams your positions, quantities, and market values into a single dashboard automatically. Instead of typing every trade by hand, the tracker reads your account through a secure key and refreshes it on a schedule.

A broker API connection is a read-only bridge that lets a third-party app see your holdings without moving your money. For Alpaca specifically, this connection reports both your equities (like AAPL or NVDA) and your crypto positions (like BTC-USD and ETH-USD) in the same feed.

The key advantage is consolidation. If you also trade on Binance, Interactive Brokers, or hold UAE names on the Abu Dhabi Securities Exchange, a tracker like PortfolioTrackr merges everything so you see one total return figure. Our guide on how to connect your brokerage account to a portfolio tracker covers the general workflow across brokers.

How do Alpaca API connections work step by step?

Alpaca API connections work by generating a read-only key pair inside your Alpaca dashboard, then pasting that pair into your portfolio tracker so it can query your account. The tracker uses the key to call Alpaca's positions endpoint and pull your live holdings.

The connection flow

1. Log into your Alpaca account and open the API keys section.
2. Generate a read-only key and secret. This lets an app view balances but never place or cancel orders.
3. Paste both values into your portfolio tracker's Alpaca integration screen.
4. The tracker calls Alpaca and imports your positions, usually within seconds.
5. After the first sync, most trackers refresh automatically every few minutes during market hours.

Read-only keys are the safest option because they physically cannot execute trades. If you want the same principle applied to crypto exchanges, our walkthrough on how to track Binance and Bybit without trading keys uses the identical approach.

What refresh frequency to expect

Position data refreshes on a schedule, not in true real time, for most trackers. PortfolioTrackr re-queries Alpaca every few minutes so your quantities stay current, while prices update more frequently through separate market data feeds. Since US stocks settle T+1 as of May 2024, a freshly filled buy shows up in your position list almost immediately.

What syncs from Alpaca and what does not?

Alpaca syncs your current positions, quantities, market value, and equity cost basis automatically, but it does not always report crypto cost basis reliably. This gap is the single most common reason gain and loss numbers look wrong after a first sync.

The table above shows the practical split. Your equity positions arrive complete, including the average entry price Alpaca calculates. Your crypto positions arrive with correct quantities and values but frequently show a blank or zero cost basis.

• Syncs reliably: open stock and ETF positions, share counts, current price, market value, and equity average cost.
• Syncs partially: dividend records and realized trade history, depending on how long the account has been open.
• Does not sync well: crypto cost basis, transfers of crypto in from external wallets, and historical closed positions before the account was linked.

Why is my Alpaca crypto cost basis missing?

Alpaca crypto cost basis goes missing because crypto average entry price is not always populated in the same position payload that equities use, and because coins transferred in from outside Alpaca have no purchase record. The API can only report what it knows, and it does not know the price of a coin you bought elsewhere.

Three common causes

• External transfers: if you moved BTC-USD into Alpaca from another wallet, Alpaca never saw the buy, so there is no basis to report.
• Incomplete API fields: the crypto position object sometimes returns a zero or null average entry price even when you bought on Alpaca.
• Pre-connection history: trades made before you linked the account may not backfill, leaving open lots with no cost.

Whatever the cause, the symptom is the same. Your unrealized gain looks absurdly large because the tracker is treating a cost of $0 as real. A 0.5 BTC position at a $60,000 price would show a fake $30,000 profit if the basis reads zero.

How do I fix missing cost basis on Alpaca crypto positions?

You fix missing crypto cost basis by manually entering the purchase price and date for each affected position inside your portfolio tracker. This overrides the blank value Alpaca returned and restores accurate gain and loss math.

Step by step in PortfolioTrackr

1. Open the flagged crypto position that shows a zero or missing cost basis.
2. Enter the average price you actually paid per coin, plus the acquisition date if known.
3. If you bought in multiple lots, enter each buy separately so the weighted average entry price stays accurate.
4. Save, and the tracker recalculates your unrealized gain using your real numbers.

PortfolioTrackr handles this by letting you edit the cost basis on any synced position without breaking the live quantity feed. Your quantity keeps updating from Alpaca automatically while your cost basis stays locked to the value you entered.

Where to find your original purchase price

Check your Alpaca trade confirmations or account statements to recover the exact price you paid. Alpaca stores order history even when the API does not surface it in the position feed. If the coin came from an external exchange like Binance, pull the buy record from that platform's transaction export instead.

Tracking crypto and equities side by side is exactly where blank basis causes the most confusion. Our guide on how to track crypto and stocks together in one portfolio explains why a single blended return figure only works when every lot has a real cost.

Is a portfolio tracker better than the Alpaca app for this?

A dedicated portfolio tracker is better than the Alpaca app when you hold assets across multiple brokers or want unified performance, tax lots, and dividend projections in one place. The native Alpaca app only shows Alpaca, which is fine if that is your only account.

• Multi-broker view: combine Alpaca with Schwab, Interactive Brokers, or crypto exchanges in one total.
• Editable cost basis: fix the missing crypto basis problem the native app cannot solve.
• Income planning: project future payouts, which our post on projecting annual dividend income across portfolios breaks down.
• Risk visibility: see how concentrated you are, useful if you read our analysis of how much of your portfolio is riding on AI stocks.

If you want a side by side of the leading options, our real data comparison of six portfolio trackers ranks them on exactly these features.

The bottom line

Connecting Alpaca to PortfolioTrackr syncs your live stock and crypto positions automatically, but you should expect to manually fix crypto cost basis on any coin transferred in or missing an entry price. Use a read-only key, verify your equity positions imported cleanly, then patch any blank crypto basis using your Alpaca trade confirmations.

Once every lot has a real cost, your total return, unrealized gain, and allocation numbers all become trustworthy. For the exact click path, follow our dedicated guide on how to sync your Alpaca account with PortfolioTrackr.
