What 20 calls can and can’t tell you

The same arithmetic applies to every track record you are shown, including trading signals.

20 IS NOT ENOUGH

12 of 20 happens to one coin in four

A fair coin gets 12 or more of 20 right 25 % of the time, and 14 or more almost 6 % of the time. To tell skill from luck you need far more calls, or calls that were locked before the outcome.

THE YARDSTICK MATTERS

Compare with a lazy guess

“Always up” scores well in a rising market and badly in a falling one, without knowing anything. A forecast only counts if it beats simple rules like that on the same days.

LOCK IT FIRST

Show the misses too

Anyone can show a winning streak after the fact. A claim counts when every call was written down before the outcome, including the ones that went wrong.

OUR OWN RECORD

We played this game with 62,907 calls

Our own crypto engine logged every score before its outcome. At that size, luck has nowhere to hide: the verdict was indistinguishable from noise, one of seven tests passed. The numbers and both reports are on the front page.
