Rules

Build Rules

Shape the player pool and constrain every lineup. Rules apply to Run Build and dim filtered players in the grid — they never delete anyone.

Player pool filters

Keep or hide players by any grid column — salary, projection, ownership, value, and every sim column (mean, percentiles, Boom%, HR, K…). Sim fields use your latest Run Sims; unsimmed players count as 0 there. Hidden players stay in the grid but dimmed, and are excluded from builds.

Stack rules

Classic Build rule

Force a team stack into every lineup — bats only, your pitchers never count toward a stack. Classic slates only. One rule at a time.

Unlike Stack Shapes, which sets a mix across your portfolio, this is a hard constraint on every entry — and it is the only place you can ask for a batting-order window or a bring-back. If nothing can satisfy it, the build says so rather than quietly dropping it.

Stack bats from any one of these teams:

(none = any team; pick teams to restrict, one for a specific-team stack)

positions: (none = all bat positions; pitchers never count)

Bat order spots: (none = any spot)

Bring back: bats from the stack team's opponent (at most 0 = nobody faces my stack)

opposing positions:

✓ No naked stacks is always on: at most 2 of your bats can ever face your own pitchers, so a 3+ stack can never face your own arm.

Player groups

Late Swap only

Cap how many of a set of players can share a lineup — e.g. at most 1 of two closers, at most 2 of three chalk bats.

Enforced by Late Swap. Build does not read it yet, so a group set here does not constrain a fresh build.

Lineup limits

Max hitters per team DraftKings caps classic MLB at 5 hitters from one team. Lower it to force more team diversity / less correlation across your lineups.

Max total ownership % Late Swap only Sum of all 10 players' Own%. Blank = off. Forces contrarian builds — chalky lineups typically total 120%+. Sum of the whole roster, not a per-player cap. Enforced by Late Swap only — it refuses any swap that would push the lineup's summed Own% over your number. Build does not read it yet; what caps exposure in a build is the grid's per-player Min% / Max%.

MLB Market Check

The Odds API's DraftKings HR, hits, total-bases and strikeout markets, collected once in the background for everyone. Refresh reads the shared cache only. Model comparisons require the same game, player and threshold. Missing or old data stays labeled; nothing changes projections or blocks Build. Replay comparisons are not proof of pregame calibration. Existing banks without threshold probabilities remain usable.

Edge Bankroll $

Ranks the day's guaranteed DK GPPs (Classic + Showdown) by expected value and lays out a bankroll allocation. Trust the ranking & the hard columns (rake, break-even edge, overlay) — absolute EV/ROI is model-sensitive and optimistic on the tails. Edge is your input (0 = field-average, ~0.1 sharp); it recommends, you enter.

Grid Audit

Daily pipeline health check: does the generated grid stay faithful to ground truth — identity joins complete, and realized actuals match the SDIO gamelog archive. Facts only; projections and sims are the engine's own model outputs and are not graded here. Reports auto-generate nightly for the finalized Main slate.
