In short
StackViewer connects to Robinhood through SnapTrade using read-only OAuth. It imports your stock and ETF positions (including fractional shares), your options positions, your executed trade history, cash balances and dividends, then merges them with any other brokers you hold into one portfolio. On top of that it runs the analytics Robinhood's app leaves out — time-weighted return, Sharpe and Sortino, drawdown, and a decision-by-decision journal. Connecting Robinhood is free. One caveat up front: StackViewer syncs three times a day, so if you trade Robinhood intraday it will lag your app.
What syncs from Robinhood
Positions
Stock and ETF holdings arrive with quantity, average cost and market value, and fractional shares come across at their exact decimal quantity — a 0.284-share position shows as 0.284, not rounded away. Options positions (single legs and multi-leg spreads) are imported with strike, expiry and side.
Trade history
Executed buys, sells, option fills and crypto trades come in as dated transactions, which is what lets StackViewer reconstruct entries and exits rather than only showing a current snapshot. How far back history reaches depends on what Robinhood exposes at connection.
Cash & balances
Settled cash and buying power are read so your allocation and cash-drag figures are accurate. StackViewer treats cash as a real slice of the portfolio, not an afterthought.
Dividends
Dividend payments are imported and land in one combined dividend calendar and income view across all your connected accounts, so Robinhood income sits next to everything else.
What does not come across: anything Robinhood's read API does not expose. Pending or unsettled orders are not treated as filled positions; margin interest, Gold subscription fees and some fee line items may not be itemised; Robinhood-specific perks such as stock-reward lots may appear simply as small share positions without their promotional context; and cash sweep balances held at partner banks are outside the brokerage feed. Non-brokerage products (Robinhood spending/debit and any retirement match accounting) are not part of the investing sync.
Sync runs three times a day and position values refresh about every 30 minutes during market hours. StackViewer is not a real-time tool and is not built for day trading.
What Robinhood's own reporting doesn't show you
Robinhood built its name on frictionless, mobile-first, commission-free trading, and its user base skews large and young — millions of retail investors, many of them in their first few years of investing. What the app deliberately keeps minimal is analytics. The portfolio chart shows a simple gain-or-loss line, and Robinhood is explicit that it "does not take the effect of compounding or mitigate the impact of cash flows," while its return figures use the Modified Dietz method and exclude external money movements like ACH deposits, withdrawals and ACATS transfers (Robinhood support, "Using charts," verified as of 2026-09-10). That is a reasonable performance measure, but it is one number with no risk context: no Sharpe or Sortino, no maximum drawdown, no volatility, no alpha or beta against a benchmark, and no view of how a single Robinhood account combines with money you hold elsewhere.
StackViewer fills that gap. It computes a proper time-weighted return so your performance is not distorted by the timing of deposits, then adds 15+ risk metrics — Sharpe, Sortino, Alpha, Beta, Max Drawdown and Value at Risk among them — and a behavioural journal. Because your Robinhood trade history comes across as dated transactions, you can tag each decision with a reason, a conviction level and the emotion behind it, then look back and see the pattern: whether you tend to sell winners early, chase momentum, or average down into losers. For a Robinhood user with options and fractional-share activity, that decision-level view is exactly what the native app was never designed to give you.
Also use Schwab?
Plenty of Robinhood users keep a Charles Schwab account too — often Robinhood for active stock and options trades and Schwab for a longer-term core of ETFs, a retirement account or a place to hold settled cash. The trouble is that neither app knows the other exists, so your real allocation, your true return and your genuine concentration risk are all split across two screens you add up in your head. Connect both and StackViewer produces a single time-weighted return across the two accounts, a combined diversification score, and one dividend calendar — rather than two apps you mentally add together.

Is it safe to connect Robinhood?
The connection is read-only OAuth through SnapTrade. You log in on Robinhood's own site — StackViewer never sees your credentials and never stores them. The token that comes back can read positions and history and nothing else: StackViewer cannot place a trade or move a dollar, and no trading permission is requested at any point. You can revoke access from inside Robinhood whenever you want.
Data is encrypted with AES-256 at rest and TLS 1.2+ in transit, authentication runs on AWS Cognito with optional TOTP MFA, and you can export everything to CSV or delete your account at any time. Full detail on the security page.
