Question 1

What does it mean for a prop firm to support ONYX?

Accepted Answer

It means the firm runs its evaluation and funded accounts on ONYX — you'll download the platform, log in with the credentials the firm provides, and trade exactly as you would on any ONYX account. The rule set (profit target, drawdown, consistency) sits behind your trades but the order entry, charting, and execution all happen inside ONYX. The 1 firm on this page uses ONYX as a primary evaluation platform.

Question 2

Do my evaluation rules change depending on the platform?

Accepted Answer

The headline rules don't change with the platform — the firm sets those. What does change is the toolset: order types, charting depth, automation support, and data quality. ONYX has its own quirks here, and traders often pick a firm specifically to keep using the platform their existing scripts and indicators were built for.

Question 3

Do ONYX prop firms charge platform or data fees?

Accepted Answer

Most firms cover the platform license during the evaluation. Data fees on the funded account are where the variation shows up — futures feeds (Rithmic, CQG) routed through ONYX can run $10–$110/month and are usually passed through to the trader. Each firm's profile on TradingPilot lists the current fee structure.

Question 4

Can I use ONYX on both the evaluation and the funded account?

Accepted Answer

In nearly all cases, yes — firms keep the platform consistent so your scripts, indicators, and chart setups carry through. A small number of firms transition to a different platform once you're funded; that's flagged on the firm profile so you can avoid the surprise.
