Lucy AI Markets
Lucy is the company's own automated trading software: it trades its own demo account today and places no trades for customers.
Lucy trades a demo account today. Trading, especially with leverage, carries a high risk of losing money.
The problem
Backtests lie by default
Almost any strategy can be made to look profitable. Mixed-interval data invents edges that never existed. Ignore spreads and financing and a losing system prints money on paper. Try a thousand variations and one will shine by luck alone. The industry calls that research; we treat it as the central engineering problem.
Every order
From the market to her demo account
How we test strategies
What we hold a test to
Verify the data before you believe the result
Historical data passes a battery of integrity gates before any strategy touches it. If the bars are inconsistent, misaligned, or silently patched, the run is refused rather than reported. A result computed on unverified data isn't a weak result — it's not a result at all.
Charge the strategy what trading actually costs
Spreads and financing are measured per instrument, not assumed. Fills are modelled honestly, including the unpleasant cases — gaps straight through a stop, entry-bar stop-outs. Most 'edges' die here, which is exactly the point.
A stop on every order
Every order carries a stop at the exchange. A price can jump past a stop, so a loss can be larger.
Let the exchange keep score
Her trading results are worked out from the exchange's own fill prices and the overnight charges it books.
