Every time you scroll through social media, you’re going to see the same thing: Winning tickets. Parlays. Underdogs. Longshots. Highlight reels of someone hitting a +800 play. Why? Because in a world with thousands of bettors firing daily, someone is always going to be on a heater. But here’s what you rarely see: An explanation of how they made the pick or the sports betting data used. Was it skill? Was it luck? Did they crunch the numbers or just roll the dice?
I can’t speak for everyone else, but I can tell you how I built a winning three-leg parlay. And it had nothing to do with superstition or guesswork. It was all about using real sports betting data.

I Used Portfolio EV — A Data-Driven Betting Tool
Here’s exactly what I did to build that parlay:
- I opened the Portfolio EV tool on OddsShopper.
- I used Portfolio Lab to backtest the market I wanted to bet into.
- I focused on a specific sportsbook — FanDuel parlays in this case.
- I checked the historical data to confirm this market had shown a consistent edge.
- I filtered for +EV bets that matched my criteria, added a boost, and locked it in.
That’s it.
Did I still need a little luck for all three legs to hit? Of course. But I knew before submitting the bet that I was standing on solid ground because each pick was backed by real, historical performance.
Why Most Bettors Lose — And How You Can Change That
This is where most bettors go wrong. They hit a big parlay and assume it was a smart bet. But unless it was built using positive expected value (+EV), it might’ve been pure luck.
That’s where Portfolio EV changes the game.
This data-driven sports betting tool breaks down every market across all major sports and identifies where the exploitable edges are. You could be betting props, sides, totals or parlays; it helps you know exactly where your sports betting edge lies.
