Was it skill, or luck?

VERDICT
07 · GBP/JPY + 5 FUTURES

Fast trend with a regression filter

A trend rule shared online, tested on six markets one at a time. On GBP/JPY we searched 9,216 versions, and all five finalists made money in a year they had never seen.

VERDICT

How we test a strategy

Five checks. Every strategy.

We take strategies people trust, run them on years of real data with costs paid, and keep testing until they hold up or break. Then we show you how to do it yourself.

  1. 01Rule first

    Written down before a single result is seen.

  2. 02Costs in

    Commission and slippage on every trade.

  3. 03Locked data

    Years it has never seen, opened once.

  4. 04Beat luck

    Against 200 random copies of itself.

  5. 05Survive the low

    The lowest point decides, not the end.

One rule against 200 random copies of itself

test data opens

Illustration. Each grey line is the same strategy with its trades moved to random days. If the white line can't stand clear of the grey ones, the profit was luck. This is the check most backtests never run.

The usual way of putting a slow chart's signal on a fast chart hands the backtest the future. The leak is big enough to make random data look profitable.

  • Was the rule written down before you looked at the results?
  • Are commissions and slippage in every single trade?
  • Could the strategy have known this price at the time?

Costs in every trade

Commissions and slippage are part of every test, never an afterthought.

Locked test data

Part of the history stays closed while you build, so you can't tune the rule to it.

A random-chance check

Your rule against random copies of itself, so luck can't pass for an edge.

Questions

Common questions

Do I need to know how to code?

No. The Lab needs no code at all. The Journey starts from zero: you learn the little Python you need, it runs right on the page, and your own AI can help at every step.

Do you sell signals or a trading bot?

No. We teach you how to test strategies. What you trade, and whether you trade at all, is your decision.

Will this make me profitable?

No one can honestly promise that. What it will do is stop you putting money behind strategies that only look good by luck.

Is this financial advice?

No. Everything here is education and research. Backtest results are hypothetical and don't predict future results.

Start with the free checklist.

You'll also get a strategy autopsy about twice a week, and hear first when the Journey and the Lab launch.
