Can I use Replay with only a NinjaTrader bridge?

Not for downloading sessions: the Replay download uses Rithmic history. Imported Databento sessions and sessions already on disk replay without it.

Where are downloaded sessions kept?

On this machine, listed as sessions on disk on the Replay screen, where you can also delete them or export their L1 as CSV.

“no broker credentials saved” when loading a Replay session

Replay downloads a session that is not on disk from Rithmic history, with the credentials of your default Rithmic connection. With no such profile or no saved password, the load fails with “no broker credentials saved”; sessions on disk and imported sessions still replay.

At a glance

Message: “no broker credentials saved”
Needed for: Downloading a session that is not already on disk
Not needed for: Sessions on disk, sessions imported from Databento files
Credentials source: Default Rithmic connection profile (keychain)

What you see

On the Replay screen, after “Load session”, the error reads “no broker credentials saved”.

Why it happens

A closed session that is already on disk opens from the disk first. For any other day, the app must download it and resolves the history credentials from the default connection profile saved in the Connection Manager; profiles store their password in the operating system keychain. When no profile with a saved password exists, there is nothing to log in with. This lookup was fixed earlier so that profiles created with the wizard are used; the message now means no usable profile was found.

How to fix it

Open Account → Broker Connections and add or edit your Rithmic profile; type the password and save it.
Test it with “Test connection” before going back to Replay.
Or replay without a broker: pick one of the “sessions on disk”, or import a folder of Databento exports.
Bridges (NinjaTrader, Quantower) and crypto feeds do not provide Replay downloads; Replay draws on CME sessions.

What it is not

Not a refused login: nothing was sent to the broker.
Not a lost Senzoukria account session.

When to contact support

If the message comes back after these steps, report it from Menu → Report a problem or on the Senzoukria Discord. If a Rithmic profile with a saved password exists and the message persists, say how the profile was created and whether live charts connect with it.
