Post-Contest DFS Simulator

Post-Contest DFS Simulator

Stop tweaking your process based on yesterday’s results–a sample size of one is meaningless. Instead, leverage simulations to review ROI for DraftKings contests at the individual lineup, user and player level.

4 easy steps to simulate contests:

1. Generate 250, 500, 1000, 1500, 2000, 5000, or 10,000 lineups using our contest generator (NFL & NBA only), or bring your own lineups.
2. Upload custom projections (or use Stokastic default projections).
3. Click “Run Contest Simulation.”
4. Review simulation data and export a CSV of your favorite lineups.

Post-Contest DFS Simulator

Feedback loops are critical. Your bankroll won’t last if you’re not dedicating time to reviewing your lineups. But if you’re looking at results alone, it will be years before you can conclude that your process is profitable. The solution? Simulations.

Post-Contest DFS Simulator

CHOOSE SETTINGS

Choose a contest, your user and any other user in that contest. We then show you three different slices of contest data for you to review.
Post-Contest DFS Sims
Review the simulated ROI of all lineups

USER ROI

Review the simulated ROI of all lineups across any user. Then compare users’ average lineup projection and ownership to identify which builds lead to the highest ROI. User ROI also varies based on contest allowing you to find the most profitable contests and those to avoid.

Frequently Asked DFS Sims Questions

What are dfs Sims?

Our DFS Contest Simulators is an advanced simulation tool that lets you simulate contests thousands of times to find the best performing lineups. While seasoned pros have long leveraged simulation tools, our simulators let you run custom simulations in minutes.
Here’s how it works: simply upload a .csv file featuring precisely 250, 500, 1000, 1500, or 2000 lineups. These lineups can be built using an optimizer, or by using our Contest Generator. From there, tailor your simulations using your own custom projections or simply use Stokastic’s reliable projections as a default option. With a click of the “Run Contest Simulation” button, your simulation will begin. Within minutes, you’ll gain access to a wealth of data points, both at the player and lineup levels. This will let you make informed decisions about which lineups to enter for any given slate.

What is the Contest Generator?

The Contest Generator is a powerful tool that enables users to quickly and efficiently create a collection of lineups that closely align with our projected ownership for a specific slate. Users can customize their pool easily by boosting individual player ownership, and setting desired stack type exposures. After the lineups are created, users can seamlessly send them directly to our pre-contest simulator for further in-depth analysis by clicking the “Simulate Lineups” button in the bottom right hand corner of the screen.

Is correlation taken into account for the simulations?

Yes. Stokastic’s proprietary simulation technology leverages hundreds of thousands of data points to integrate correlation directly into the simulations. With correlation built in, you can confidently test out how different team stacks and stack types perform over thousands of simulation runs for a given slate.

How do I build my contest pool?

Using our Contest Generator, or any other optimizer of your choice, you can quickly and effectively create your contest pool. We recommend building a lineup set that mirrors what the field will look like for the contest you plan on entering. The more accurate your pool of lineups reflect the actual lineups that will be in the contest you are playing in, the better your simulation results will be.

Which metrics are most important to look at?

While all the metrics on both the pre and post contest simulator tools are important, the gold standard metric is the ‘Simulated ROI%’ column. This column presents a lineup’s ROI percentage based on the simulations that were ran. It’s the gold standard metric, essentially ranking the lineups from best to worst.


What is the difference between the pre and post contest simulations?

The pre-contest simulation tool relies on the user’s inputs for both the lineups and the projections. It will provide insights based only on the uploaded lineups.
The post-contest simulation tool takes the actual lineups that were entered into a contest on DraftKings, and runs a simulation on them. There are no user inputs for this tool, as it relies on the exact lineups that were entered and Stokastic’s projections to run the simulation. This tool is only available for DraftKings contests.

What sites do these tools support?

We support DraftKings, FanDuel, and OwnersBox for the contest generator and pre-contest simulations. Post-contest simulations are only supported on DraftKings and OwnersBox contests.

Why is Fanduel not supported for the post-contest simulator?

Unfortunately, FanDuel does not support the exporting of their contest files like DraftKings does. Therefore, there is no way for us to retrieve the actual lineups that are being used for the contests. Without the actual lineups, there is no way for us to run a post contest simulation.

How is this different from other simulation tools on the market?

Game level simulation tools exist on the market currently to help users with projecting player performance. However, nowhere else do users have the ability to perform simulations on the contest level, making this tool one of a kind. This tool allows for analysis at the lineup level to help you find the edge. Gain insights into how ownership impacts ROI, which teams and stack types are most profitable, and which players contribute most to high ROI lineups.
