Does Atradian need my broker login?

No. Portfolio X-ray works from a screenshot, CSV or pasted holdings. Atradian does not ask for a broker login or trading access.

Can I check a number before it is saved?

Yes. You confirm every figure in the import before it is accepted, and each accepted snapshot is reconciled against the broker's total.

How often should I update it?

Whenever you want the brief to reflect your holdings. Pro checks the portfolio against your rules every trading day, while the free plan's brief is weekly. Either way, the brief shows how old the last snapshot is.

Portfolio X-ray without linking your broker

Atradian's Portfolio X-ray analyses your holdings without a broker login or trading access. You upload a screenshot, CSV or pasted positions, confirm every figure, and get look-through sector exposure, ETF overlap counts and a check of your own rules against each saved snapshot.

Why skip the broker link

Connecting an app to your brokerage account gives it more access than most analysis needs. A portfolio review only needs to know what you hold, how much, in which currency and what cash you have. You can give that to a tool by hand and keep the trading permissions with your broker.

How the update works

Export or screenshot. Take a screenshot of your broker's positions screen, or export a CSV, or paste the table.
Confirm every figure. Atradian shows the parsed positions, cash and totals. Nothing is saved until you accept it.
Reconcile. Each accepted snapshot is checked against the broker's own total, so a misread row shows up as a difference rather than passing silently.
Compare. The new snapshot is compared with the previous one, so you see what changed.

Each broker account keeps its own currency, cash and totals, so a multi-broker or multi-currency portfolio can be combined without converting by hand.

What you get from the snapshot

Look-through sector exposure. Sector weights, with the holdings behind each sector, including exposure held through funds.
ETF overlap. Where two funds disclose the same top positions, the overlap is shown. These counts are a lower bound, because they only use the holdings each fund discloses.
Rule checks. Your own rules, such as a position-size limit or a price review, are checked against each snapshot, and the brief says when a rule changes state.

The trade-off

You update the snapshot yourself, so the data is only as current as your last upload. A portfolio you do not update will drift from reality, and the brief will say how old the snapshot is. If you want changes detected automatically, a broker link does that, but it also asks for more access.

Who it suits

Investors who review their portfolio on a schedule, want to keep broker access out of third-party apps, and are comfortable confirming a few figures each time. Atradian does not place trades and does not hold your funds. See how to monitor your portfolio without checking daily for a routine that fits this approach.
