Does This Trade Have Positive Expectancy?

A trade idea is only positive expectancy if the assumptions survive pressure.

Modeled expectancy is not proof. It is a transparent estimate from probability, average win, average loss, costs, sample size, tail losses, and account risk. Small assumption errors can flip the sign.

What the tool evaluates

This site weighs the trade decision using visitor-entered assumptions. It highlights the strongest argument for action, the strongest argument against it, missing information, and practical steps that could improve the setup.

Plain-English limitation

The result is not a prediction. It cannot see live prices, order-book depth, broker rules, tax treatment, or your personal situation. It turns your assumptions into a disciplined review.
