You type your rules the way you would explain them to another trader. The desk turns them into code, runs them over whatever stretch of history you ask for — a year, five, or as far back as the data goes — and emails you a report with every trade in it, usually within a day.
No pseudo-code, no platform syntax, no account with anyone else, and no limit on how many times you do it.
The session running at the top of this page is this terminal at a tenth of the size. Pick any date since 2016, cut the chart there, and step the market forward at your own speed with a real order ticket — leverage, fees, stops, position sizing off your risk.
Future bars are never in the chart at all, so they cannot be peeked at by dragging. Every candle behind you on the way here came out of the same history the terminal runs on.
The two products are the same idea at two speeds. Numbers tell you whether a system works; replay tells you whether you could have followed it. Most systems die on the second question — and no one else sells both ends of it.
The Machine runs the rules across every regime and hands back the numbers.
Replay the trades the report lists and find out what they felt like at the time.
Adjust the rules and run it again. Either half alone is a tool; the loop is the product.
The point is to run a system until it works, and a credit counter fights that. The yearly price is shown as what it costs a month, because that is the number anyone actually compares.
Professional quantitative backtesters. Every figure comes from itemised execution records over multi-year historical cycles — the lower-timeframe history that is close to impossible to pull by hand — so compounding is shown rather than claimed.
Historical data is Dukascopy tick and minute history, rebuilt and verified against the record. Nothing here is investment advice, and a backtest is a measurement of the past rather than a promise about the future.
There is nothing to install and no syntax to learn. Write the rules the way you would explain them to another trader; the desk codes them, runs them over the period you ask for across bull, bear and ranging markets, and emails a report with every trade listed.
Two products. Take the machine that tests a system for you, the terminal you trade the past on, or both — and run as many backtests as it takes.
BarTest Replay & Chart, in full. Trade the past bar by bar on your own account, at your own speed.
The Backtest Machine on its own. Submit a system, get the full report back — as many times as it takes to find one that works.
Both products, and the loop between them: test a system, watch it fire in replay, change it, test it again.
Trading Campus and the System Building Factory are still under development and are not part of any tier yet. They will be added as they open — no tier is priced for them today.
USDC cannot recur, so a crypto payment buys one month of a tier outright and then lapses. Card subscriptions renew until you cancel, and cancelling keeps your access to the end of the period you paid for.
