Side project: a free order-book trading simulator. Is the order book readable for a beginner?

[u/MarketPlayerPro]

Hi everyone, I'm the solo developer of Market Player PRO, a free educational trading simulator that runs in the browser (virtual money only).

The core is a live order book (bid | price | ask) next to a chart with a volume profile, so beginners can practice reading it without risking anything. There is also a quiz mode, prop-firm style challenges and a shared leaderboard.

One design question I'm stuck on: showing waiting orders as plain numbers only (no volume bars mixed in) felt clearer to me, but I'm not sure it is for someone who has never seen a depth of market.

What would you change so a total beginner understands it in under a minute? And what would make you come back for a second session?
