Prüfstand

Trading strategies tested under identical conditions

Walk-forward · 15 windows · real fees · forward test

Most strategies do not work. Find out whether yours is one of them.

Enter your rule, pick up to five markets and press Test. Three tests a day, no account, no sign-up, no e-mail. You get the same verdict as everyone else — on the same data, with the same fees, across the same fifteen time windows.

We also test on data that did not exist when you submitted. That data cannot be overfitted — not even by us.

1 — Indicators

2 — Rules

Allowed: > < >= <= and or not + − × ÷ numbers
and the names of your indicators. No code — nothing is executed.

3 — Markets

A rule that only works on one market has memorised that market. Several markets in a single run show the difference.

4 — Appear in the register as

A random handle is filled in by default. If you want to be named, overwrite it — otherwise no name appears. The handle stays the same so the attempt counter cannot be sidestepped by changing names.

This is what gets submitted


      
A readable file, not a program. Download it, pass it on, submit it again whenever you like.

    


    

      
      
      
        
        
      
    

  


  
  
  

  
  

    

      
Same conditions for everyone

      
Same prices, same fees, same windows. The data revision and its checksum are printed in every report — anyone can recompute it.

    

    

      
Attempts are counted

      
Submit twenty variants and one will shine by chance. So every verdict states which attempt it was. Yours included.

    

    

      
Forward, not backward

      
From submission onward, only what happens next counts. Nobody can overfit that number — we cannot either.

20tests a day

9 €per month, incl. VAT

        
  • 50 tests a day
  • Every market and candle length, no ten-market cap — a rule tested across all twenty-four markets leaves no doubt whether it is worth anything
  • Portfolio instead of single market: several strategies in one account, sharing a risk budget and a total loss limit — the way it actually runs when it matters
  • A weekly forward report, not just the verdict at the end
  • Every candle, every trade, every window as a file you can recompute
  • Cancel monthly, no minimum term

      


    

    
Three a day sounds like very little, and that is the point. Anyone working through twenty variants is no longer searching — they are waiting for one to shine by chance. That is exactly what this service warns about one heading further up. A limit that guards against it is not a gate at the door; it is part of the method.

    
Which is why no amount of money buys unlimited tests. The Workbench costs something because it computes more — every market instead of ten, a portfolio instead of a single rule, every week instead of once. It does not cost something so you may submit the same idea more often. The attempt counter keeps running on every tier and is never reset. It appears in your report and in the public register, visible to all — including for those who paid.
