BLKJ is the discipline layer for prediction market trading. 54 rules across 10 sports, sweet spot probability zones, a morale meter, and a journal that proves whether your own system actually works.
BLKJ scans live Kalshi markets across 10 sports and classifies every one of them against your own discipline rules, automatically, in real time.
Every market across soccer, tennis, UFC, baseball, basketball, football, hockey, boxing, motorsports, and golf is pulled live and re-checked every 60 seconds.
Each market gets a verdict, Sweet Spot, Borderline, or No Trade, based on sport-specific probability zones calibrated from real outcome data.
Every trade you place is logged automatically. Your Journal and Analytics show whether your rules actually held up, broken down by sport and verdict.
Every feature exists to slow you down and force a real decision, not speed you toward a tap.
Per-sport probability bands calibrated from real win-rate data, not a single arbitrary number across every sport.
Flag injuries, rotations, and live energy you can see. It informs your judgment, it never silently changes the verdict for you.
Every trade logs automatically with the verdict and probability at the time. See your real Sweet Spot vs Borderline win rate.
See every upcoming market across all 10 sports in one calendar view, with reminders before kickoff.
Toggle any of the 54 rules, adjust thresholds, and reset per sport independently, your system, your numbers.
Export your full trade history as a CSV any time, every stake, verdict, and result, ready for your own records.
Each sport's Sweet Spot zone is tuned to how that sport's outcomes actually distribute, not a one-size-fits-all probability cutoff.
22 apply across every sport. 32 are sport-specific, tennis retirement risk, UFC weight cuts, baseball bullpen fatigue, and more.
Outside the zone, the math does not work long term.
Teams managing a win do not chase more goals.
Kalshi's fee structure peaks near 50% probability, a thin edge rarely clears it.
Less camp time historically underperforms the listed odds.
No tiers to compare, no features held back behind a higher price.
