What separates traders who generate steady returns from those treading water or suffering losses is rarely about raw forecasting talent alone—it's fundamentally about discipline and methodology. This guide outlines the core habits that successful market participants follow in their daily operations.
Before Entering Any Position
- Articulate your edge: What insight gives you an advantage that the broader market lacks? Commit this to a single written statement prior to committing capital.
- Check the spread: Does the gap between buying and selling prices allow your advantage to overcome fees and slippage?
- Assess liquidity: Will you be able to unwind this holding at a reasonable price if circumstances change? Review the depth of available orders.
- Set your probability independently: Establish your forecast without consulting market quotations first, thereby shielding yourself from anchoring effects.
- Calculate position size: Apply the half-Kelly approach. Keep individual stakes capped at 5% of total capital regardless of confidence level.
During Position Management
- Update on new information: As significant events unfold (speeches, economic figures, announcements), reassess your forecast and determine whether to increase, maintain, or liquidate your stake.
- Don't check obsessively: Momentary price swings represent statistical noise rather than genuine shifts. Monitor your holdings once daily for markets with extended timeframes.
- Pre-define your exit criteria: At what level will you close out if your thesis proves incorrect? Lock in this threshold beforehand to prevent emotion-driven choices.
After Each Market Resolves
- Record everything: Timestamp, venue, your forecast, entry price, final result, gains or losses
- Score your calibration: Did your 70% predictions end up correct roughly 70% of the time?
- Categorize by market type: Do you perform better in certain domains such as elections versus digital assets versus athletic events?
- Review your losers honestly: Did faulty reasoning lead to this loss, or was the methodology sound despite an unlucky outcome?
Weekly Review Routine
- Reconcile all holdings and net gains/losses
- Compute rolling 30-day and 90-day Brier scores
- Survey the schedule for forthcoming key events (central bank announcements, electoral cycles, significant economic indicators)
- Spot any recurring patterns or tendencies in your recent activity
- Adjust portfolio mix as warranted
FAQ
- How often should I review my prediction market performance?
- A weekly cadence suits most practitioners. Reviewing daily encourages excessive trading; waiting a full month risks missing chances to make adjustments.
- What software should I use to track prediction market trades?
- PolyGram's integrated tracking system provides a solid foundation. For deeper insights, export your transaction log to CSV format and work through it using Excel/Google Sheets or Python scripting.
- How many markets should I research before entering each week?
- Depth of analysis matters far more than breadth. Thoroughly investigating 3-5 opportunities typically yields better results than superficially reviewing dozens.
