In trading slang, “+EV” usually means “positive expected value” under a model: the idea that repeating similar bets at similar prices would—on average—produce a favorable outcome. On prediction markets, that concept is useful for disciplined thinking and dangerous when treated as a guarantee.
Models can be wrong
Every +EV label depends on assumptions: fair probability, fee treatment, liquidity, and whether the contract resolves the way you think. If the model is wrong, the sign flips. Treat +EV outputs as hypotheses to investigate, not instructions.
How Predlyx uses +EV
Predlyx provides a +EV finder to help you discover rows worth reviewing with fees in mind. It is an analytics tool for people who already understand that markets can move against you and that “edge” is never free.
If you are learning
Start small, read each exchange’s rules, and separate research time from execution time. Consider recording decisions and outcomes so you improve your process over weeks, not minutes.
Predlyx offers a 7-day trial and paid plans if you want the full scanner experience—see pricing for details.
