What is the Onyx platform?
Onyx is our trading platform hosted and powered by Rithmic. It uses Rithmic’s professional futures trading infrastructure for order routing, execution, and market data, while using full TradingView charts.
If you are familiar with Rithmic-based platforms, Onyx operates on the same backend technology.
Is Onyx powered by Rithmic?
Yes. Onyx is fully powered by Rithmic.
This means:
Orders are routed through Rithmic
Market data is provided by Rithmic
Platform availability follows Rithmic market hours and maintenance schedules
Where can I view my trade history?
All Onyx trade history can be accessed through rTrader Pro.
You can view:
Executed trades
Order fills and timestamps
Account-level trade history
Even if you trade using a different front-end, rTrader Pro is the source of record for all Onyx accounts.
When are Onyx accounts created and processed?
Account purchases made during market close are not processed immediately.
This includes purchases made:
On weekends
During daily market maintenance
Accounts will be processed closer to market open, once Rithmic systems are fully online.
This delay is normal and expected.
What are the futures market hours (ET)?
Onyx follows the standard CME futures schedule:
Market Open (ET):
Sunday at 6:00 PM ET
Market Close (ET):
Friday at 5:00 PM ET
Daily Maintenance Window (ET):
Monday–Friday from 5:00 PM to 6:00 PM ET
Can I log in during market close or maintenance?
In most cases, no.
During:
Weekends
The daily 5:00–6:00 PM ET maintenance window
Rithmic performs system maintenance. During this time, you may be unable to:
Log in to the platform
Sign agreements
Complete account creation
Access account credentials
This is expected Rithmic behavior and does not indicate an issue with your account.
I can’t log in — is something wrong with my account?
Most likely no.
If you are attempting to log in during:
A weekend
The daily Rithmic maintenance window
Please wait until the market reopens. Access will restore automatically once maintenance is complete.
Submitting a support ticket during these times will not speed up access.
