How it works
From salary file to uploaded lineups in six steps. Works the same for NFL, NBA and college football on DraftKings and FanDuel.
- 1
Download the salary file
DraftKings: open any contest, then Export to CSV next to the player list. FanDuel: open a contest, then Download players list. Do this on a computer; the sites’ upload tools are desktop only.
- 2
Upload it to the optimizer
Open the optimizer and choose the file. The site detects the sport and contest type, loads today’s player props and game lines, and replaces season averages with projections from the betting markets. Players who are out are removed automatically.
- 3
Set your exposure and rules
Choose how many lineups to build and how different they must be. Set a default maximum per player, then type a Min % or Max % next to anyone you want more or less of. Football slates add stacking rules. Lock a player to put him in every lineup, or mark him out.

Build and check the report
Click Optimize. Each lineup appears with its salary and projection, and the exposure report shows how many lineups every player landed in, compared with the range you set.
- 5
Get your lineups onto the site
Easiest: join your contests first, download your entries file (DraftKings: Lineups, Edit Entries, Download; FanDuel: My Entries, Download), then click Fill my entries file. Upload the filled file back on the same page. Your best lineups go into your most expensive contests.
Or: click Download upload CSV and use the site’s Upload Lineups page. - 6
Check for late news before lock
Props update at set times before games start. If a player is ruled out, click Check for new props, rebuild, and fill your entries file again. Lineups for later games can still be changed after earlier games lock.
Questions and answers
Is using PropForge allowed on DraftKings and FanDuel?
PropForge never logs in to your account and never automates anything on their sites. You download files from them and upload files back yourself, the same way every major lineup optimizer works. Always follow each site’s terms.
Where do the projections come from?
From sportsbook player props: points, rebounds and assists in basketball; passing, rushing and receiving yards, catches and touchdown odds in football. We remove the sportsbook’s margin, turn each line into expected stats, convert them to fantasy points for your site’s scoring, and blend in the season average and the game’s expected score.
When do props update?
At set times before games, US Eastern: NBA at 3:00, 5:30 and 6:30 PM on weekdays; NFL Sundays at 9:00 AM, 11:35 AM (after inactives), 3:10 PM and 7:30 PM; college Saturdays at 9:00 AM, 11:15 AM, 3:00 PM and 6:30 PM. The optimizer shows when the next update is.
What does exposure mean?
The share of your lineups a player is in. With 20 lineups, 30% means 6 lineups. Lower exposure spreads risk; if a player has a bad game, fewer of your lineups go down with him.
What is a stack?
Pairing a quarterback with his own receivers so their points rise together. A double stack uses two receivers. The optimizer can require a stack in every lineup and a double stack in a share of them.
Why was a player left out?
Our default rules remove players who are out or doubtful, questionable players (unless you lock them or give them a minimum), quarterbacks with no passing props (usually backups), and receivers projected for fewer than about four catches. Click the X in his row to bring him back, or turn a rule off.
What does “Fill my entries file” do?
It writes your lineups into the entries file you downloaded from the site, best lineups into the most expensive contests first, and checks every player ID against that file. If you have more entries than lineups, it reuses your best lineups and tells you.
What is the odds board?
The odds board shows each player prop at every US sportsbook we track, the best price for the Over and the Under, and where the books disagree the most.
Does this guarantee I’ll win?
No. Better projections and smarter exposure improve your odds over many slates, but daily fantasy involves luck, and most lineups in large contests don’t cash. Play only what you can afford to lose.
Does it cost anything?
PropForge is free to use right now. Paid plans with a 7-day free trial are coming soon.
