The problem

You can't get good at something you never practice.

✗Paper trading Runs at real speed. A year of practice takes a year.
✗Backtesting Gives you a number in one second. You never make a single call, so you never get better at making one.
✗Real money Teaches fast. You don't get to pick the price.

Prop Desk sits in the gap. You get the reps of a backtest and the decisions of live trading. Step through a real recorded day, bar by bar, from a tenth speed up to 4x. Trade it the way you'd trade it live.

Playable now

Don't take my word for it.

An early build runs in your browser right now. Real recorded market data, bar replay, live P&L. It's rough and it's missing things. That's the honest state of it today.

In the moment

You get filled where you clicked.

Go long or short at the price on screen. Your position, equity, open profit and worst drawdown move with every bar. At the closing bell you're flat, and you read the session back: win rate, average win, average loss, profit factor.

A simulator that flatters you is worse than no simulator at all.

The lab

It shows you what didn't work.

Most trading products only show you the wins. The lab shows you the rules that failed: how many times it was tested, what it did after costs, the worst drawdown, and whether it beat doing nothing at all. If it didn't, it's marked rejected, and it stays marked everywhere in the game.

Is this for you?

Probably, if you're one of these.

→New to trading and don't want to learn with money
→Been paper trading and it's too slow
→Can read a chart but freeze when it's live
→Want to test a setup a hundred times, not twice
→Curious whether your rules hold up at all
→Just want to see what a real trading day feels like

It's a game. Nothing here uses real money, and it never will.
