How To Manage DFS Lineups: NBA Sims Portfolio Manager

If you play NBA DFS in bulk, you already know the part that steals your time isn't building the lineups. It's everything after. You run the Sims, you save your favorites, and then you're stuck shuffling CSV files between the site and a spreadsheet, making sure every lineup ends up in the right contest. This is how to manage DFS lineups without any of that: the DFS Portfolio Manager inside the Stokastic Sims kills the manual CSV-editing step. Here's exactly how it works, start to finish.

Summary: What You'll Do

• The Portfolio Manager (the Entry Manager button in the Stokastic Sims) lets you manage your NBA DFS entries without ever editing a CSV or copying lineups by hand.
• You download your contest file from DraftKings or FanDuel, load it into the Sims, populate your saved lineups, and download an entry file that's ready to re-upload. The workflow is the same on DraftKings or FanDuel (the walkthrough below runs on DraftKings).
• Lineups are chosen by simulated ROI, and you can lock in a uniques setting so every entry differs from the others by a set number of players.
• In the NBA, where you don't always have time to react to late news, cutting the manual file work back is the difference between getting your lineups in and missing lock.

For years, entering a big NBA DFS slate meant babysitting spreadsheets: open one CSV, copy data into another, double-check that every lineup mapped to the correct contest, and make sure you copied the right data into the right columns. That whole chore is gone now. You manage your entries entirely inside the Sims and never open a CSV to edit it. Below is the walkthrough.

What The Portfolio Manager Actually Does

The Portfolio Manager is a feature built into the Stokastic simulation tools. Once you've run a Sim and saved some lineups, a new Entry Manager button appears in the top-right corner of the Sims. That button is the whole system: it reads the contest file you export from your DFS site, matches your saved Sims lineups to your registered entries, and hands you back an upload-ready file. No copying lineups from point A to point B.

The process is the same whether you play DraftKings or FanDuel (and if you're weighing the two, we broke down FanDuel vs. DraftKings for DFS separately). In both cases you download a CSV from the site that carries your contest information, load it into the Sims, and proceed the same way. The site changes; the workflow doesn't.

Step 1: Download Your Contest File From DraftKings

Start on the site you're entering. On DraftKings, that's the entry-upload (edit-entry) screen for the contest you've already entered. Register the entries you plan to play first, then download that contest file and save it somewhere you'll remember. This file is what tells the Sims which contest you're in and how many entries you have.

The same idea applies on FanDuel. You're always grabbing the site's contest CSV first, because that's the file the Entry Manager reads to know where your lineups are going.

Step 2: Open The Entry Manager In The Sims

Back in the Stokastic Sims, click the Entry Manager button in the top-right corner. It asks you to upload a CSV. Choose the contest file you just downloaded from DraftKings, and the Sims immediately pull in your entries.

In the walkthrough, the file showed 19 registered entries even though 50 lineups had been saved in the Sims. That's fine. You just click Save and Continue and the Entry Manager knows you need to fill 19 slots. Whatever your registered entry count is, that's the number the tool works toward.

Step 3: Populate The Lineups You'll Enter

Now head to the lineups page in the Sims. If you want a clean slate, unfavorite everything first so you're starting fresh, then tell the Sims to favorite the exact number of lineups you need to fill your entries.

This is where the Sims do the heavy lifting (if you're new to how they build, start with how to make DFS projections). Two settings matter:

• Uniques. Set how many players must differ between any two of your lineups. In the demo it was set to three uniques, so every lineup differs from the others by at least three players. That's how you avoid entering 19 near-identical builds (more on why that matters in our DFS diversification strategy).
• Custom Amount. Favorite the specific number of lineups you need. Here it was 19, to match the 19 registered entries.

Click done, and the Sims return the best lineups by simulated ROI while enforcing your uniques rule. To keep every lineup unique, it will leave gaps rather than force in a duplicate structure. You end up with the count you asked for, all saved and ready.

Tip: Dial your player pool on the Stokastic NBA DataHub (projections and ownership) before you favorite. The Portfolio Manager only enters the lineups you saved, so the work is in the build, not the upload.

Build the pool this manages. The Portfolio Manager only ships the lineups the Sims built, so the important work happens upstream in the NBA Sims: simulate the slate, then favorite by simulated ROI with your uniques locked. Run your first NBA slate on the free Sims, and when you want to build in bulk and manage every entry from one screen, code DFSLINEUPS10 takes 10% off your first week or month of Stokastic NBA Data + Sims.

Step 4: Add To The Entry Manager And Download The Entry File

With your lineups favorited, click Add to Entry Manager. The Entry Manager screen comes back up showing the contest you're in, laid out with its details so you can confirm it's the right one. If you'd registered for multiple contests, every one of them would be listed here.

Click the plus sign next to the contest, and your favorited lineups are applied to the file instantly. Then click Download Entry File and save it back to the same folder. That's the file you'll hand back to the site.

Step 5: Upload The File Back To DraftKings

Return to DraftKings, to the exact same screen where you downloaded the contest file. This time you hit Upload and select the entry file the Sims just built. You'll see a confirmation that it uploaded your lineups, for example "successfully uploaded 19 of 19 lineups." Open the contest's lineups view and there they are: your unique Sims builds, entered and ready.

If you'd been in multiple contests, the Entry Manager would list each one, and you could apply those same lineups across every contest you entered. One build, every contest, no spreadsheet.

Why This Matters Most In NBA DFS

Speed is the whole point in the NBA. Starting lineups drop late, a star gets ruled out an hour before tip, and suddenly the value play you needed to be on is obvious to everyone. That is what makes NBA DFS lineup management its own skill: when your entry work is a manual CSV chore, that's time you don't have. This tool compresses the last mile, the part between "I have my lineups" and "my lineups are in," so you can react to news and still make lock.

It's the same reason we build in the Sims in the first place: get the process out of the way so the only thing left is the DFS decision itself, which players to be on.

FAQ

What is the Stokastic Portfolio Manager? It's a feature inside the Stokastic Sims (the Entry Manager button) that lets you manage and upload your DFS entries without opening CSV files or copying lineups by hand. It matches your saved Sims lineups to the contest entries you've registered on your DFS site.

Does it work on both DraftKings and FanDuel? Yes. The process is identical on both. You download the contest CSV from the site, load it into the Sims, populate your lineups, and download an upload-ready entry file to send back.

How does it choose which lineups to enter? It selects your favorited lineups by simulated ROI while enforcing the uniques setting you pick, so every lineup differs from the others by the number of players you specify.

Do I still have to register my contests first? Yes. Enter the contests you want to play first, then download the contest file. The Entry Manager works toward the number of entries you've already registered.

Example: The How-To 5-Step Flow For 19 NBA Lineups

Step	Where	What You Do
1. Download Contest File	DraftKings / FanDuel	Register your entries, then download the contest CSV
2. Open Entry Manager	Stokastic Sims	Click Entry Manager (top right), upload that contest file, Save and Continue

5. Re-Upload	DraftKings / FanDuel	Upload the entry file on the same screen; confirm "X of X lineups"

The Bottom Line

Managing NBA DFS lineups used to mean copying CSVs from one spot to another and hoping nothing broke. Now it's a handful of clicks: download your contest file, open the Entry Manager, populate your lineups by simulated ROI with your uniques set, download the entry file, and re-upload it. Whether you run one contest or spread the same pool across every contest you entered, on DraftKings or FanDuel, the workflow does not change.

The leverage is in what fills those entries. The Sims build and trim your unique lineups by simulated ROI so the only thing left is the upload you just learned. Try the free Sims to run your first NBA slate, and when you want to build in bulk and manage entries with the Portfolio Manager, code DFSLINEUPS10 takes 10% off your first week or month of Stokastic NBA Data + Sims.
