The fee truth: two of our three trading paths were negative after costs
We ran the numbers on our own executions — not the win rate, the friction. On two of three paths, fees ate more than the entire gross profit.

Here things get tested, not believed.
What this section is for
We test signals — the sensible ones and the crazy ones — against real data and publish what survives and what dies. No backtest flattery, no curve fitting behind closed doors. When a thesis falls, you watch it fall. For everyone who wants to know whether there is a method behind a number, or just a good story.

Lab story: the week fees dismantled our strategy
Our trading lab learned more about fees in one week than from any textbook: trade geometry decides, not win rate.
A strategy with a 78% win rate can lose money: if the average stop-loss is a multiple of the average take-profit and fees eat most of the gross win, the break-even win rate sits above the real one. That is exactly what we measured in our lab — and we publish the numbers.
