The replay terminal as it looks today. Simulated session, no real orders. Click any screenshot to enlarge.

Learn it on replay. Not on a paid evaluation.

A live chart gives you one pass at each session and no rewind. Replay gives you the same session as many times as you need. The Strategy Lab shows whether a rule held up on data it was not tuned on.

On a live chart

One look at each setup. If your stop was too tight, you find out with money on the line, and you cannot go back and try a wider one.

In replay

Rewind the same morning. Change the stop, the size or the entry and see what changed. Then run the rule over the whole dataset instead of one week.

Five steps. One window.

What a session looks like. Every screenshot on this page is the real app.

Read the session first.

A volume profile with the point of control, value area high and low, VWAP, session high and low, and the nearest prior-day volume POC, all with distance in ticks.

Session or RTH profile, from half-point to 5-point rows
Profile is estimated from 1-minute bars and labeled "est." in the app

Volume profile and key levels.

Replay it at your speed.

Play the day at up to 30x or step one bar at a time. Jump to any date in the dataset. VWAP, EMA, value-area levels and demand zones draw on the chart as the session unfolds.

1-minute, 5-minute and 15-minute views
Pause, step, or restart the day

Replay chart of MES with VWAP, EMA9, value area levels and cumulative volume delta — Replay chart with VWAP, EMA and prior-day levels. Simulated.

Place the trade on paper.

Buy, sell or flatten with hotkeys. Set take-profit and stop in ticks, with slippage and a fee per round trip, so the P&L you see is after costs.

Session P&L, win rate, profit factor and drawdown update live
Every order is logged as a structured record you can export

Position, radar and stats panels with bracket and fee settings — Position, radar and session stats. Simulated, no real orders.

See what the book was doing.

On days loaded with real trades and order book depth, switch to Order Flow. Resting size shows as a heat map, traded volume as bubbles, and the footprint and tape sit on the same time axis.

Filter to big prints only
Delta, CVD, and tape speed on the side panel
One loaded day shows 129,846 real trades and 1.89 million price levels

Order book heat map with traded volume bubbles — Heat map: bright is big resting size. Bubbles are traded volume.

Footprint chart with bid and ask volume per price and cumulative delta — Footprint with CVD underneath.

Test the rule on years of bars.

Write a rule in plain JavaScript, run it over the full history, and read the result after fees and slippage. Stats are split into in-sample and out-of-sample, so you can see whether it held up on data it was not tuned on.

Win rate, profit factor, expectancy, drawdown, longest losing streak

Strategies are saved on your computer

Strategy Lab code editor with a saved list of strategies and the API reference — Write the rule. A saved library and an API reference sit beside the editor.

Strategy Lab backtest with in-sample and out-of-sample statistics, equity curve and trade list — A basic swing-break rule over 903 trades. Modest edge in-sample, weaker out-of-sample. That is the point of the split: you find out here. Simulated, with assumed fees and slippage. Not financial advice.

Volume profile

Where it fits. Where it does not.

Larger platforms do more, and several have free tiers or trials. Here is the honest comparison.

	Prop Desk Tool	Typical full platform
Data resolution	1-minute bars, plus real trades and order book on loaded days	Often tick-level for the whole history
Order flow	Real heat map, footprint and tape on loaded days. Volume profile in the main view is estimated from bars.	Real tape and footprint across most sessions
Strategy testing	Built into the replay. JavaScript rules, in-sample and out-of-sample split.	Usually a separate tool or its own scripting language
Live trading	No. Practice and testing only. [NEEDS REVIEW]	Often yes
Setup	Install and load your data	Account, data subscription, configuration

Choose Prop Desk Tool for fast, focused practice and rule testing on MES. Choose a full platform if you need live execution or tick data for every session.

Built for a narrow job.

Built for

Traders preparing for a futures prop-firm evaluation
Self-directed MES day traders who want to rehearse setups
People who write rules and want a fast backtest loop

Not for

Anyone looking for trade signals
Live trading or broker connections
Anyone hoping for a promise of profit. It is practice and testing only.

Why I built it

I built this tool because I could not find anything out there that had what I needed. So I built it myself.

Straight answers.

Is this real trading?

No. Everything is simulated. Results in replay or the Strategy Lab do not predict real trading results.

What does it cost?

Planned launch price: $99, one time. No subscription. People on the early-access list get it first, with the launch details. For context, replay and backtesting subscriptions we checked on 2026-11-03 run from about $15 to $60 a month, and there are no refunds, so look through the screenshots first. [NEEDS REVIEW: Evans to confirm $99]

Is the order flow real?

The Order Flow view uses real trades plus order book depth on days where that data is loaded. The volume profile and delta in the main view are estimated from 1-minute bars and labeled "est." in the app.

Where does the market data come from?

You bring your own historical MES data from a source you are licensed to use. [NEEDS REVIEW: confirm before launch]

Where are my strategies and logs kept?

Strategies and order logs are saved on your computer.

Windows or Mac?

[NEEDS REVIEW: list the platforms you have tested]

Will it help me pass a prop-firm evaluation?

It is a practice tool. It cannot promise a pass, and it is not affiliated with any prop firm.

Refunds?

No. All sales are final, so look through the screenshots and this FAQ before you buy. Everything shown on this page is the real app.

Is this the same as the Prop Desk Trading game?

No. Prop Desk Trading is a separate simulator game that is free to play in the browser. This is a desktop tool for MES replay and rule testing. Early-access buyers also get the full game included. [NEEDS REVIEW]

One price. No subscription.
