What separates traders who generate steady returns from those who merely break even—or worse, lose capital—is typically disciplined methodology rather than raw forecasting skill alone. This guide outlines the core procedures that institutional and experienced independent traders follow on a regular basis.
Before Entering Any Position
- Articulate your edge: What insight or information do you possess that the broader market has overlooked? Commit this reasoning to a single, clear statement prior to executing any trade.
- Check the spread: Does the gap between buying and selling prices remain tight enough that your competitive advantage surpasses the cost of transacting?
- Assess liquidity: Will you be able to unwind this position at a favourable price if circumstances demand it? Examine the depth of available orders.
- Set your probability independently: Develop your forecast in isolation before consulting market quotations, thereby guarding against the tendency to be influenced by existing prices.
- Calculate position size: Apply the half-Kelly criterion. Never risk more than 5% of total capital on any single trade, regardless of how confident you feel.
During Position Management
- Update on new information: When significant events materialise (speeches, economic indicators, breaking news), reassess your forecast and determine whether to increase exposure, maintain your stake, or close out.
- Don't check obsessively: Minor price swings throughout the day represent statistical variance rather than meaningful signals. Monitor your holdings once daily for markets with longer timeframes.
- Pre-define your exit criteria: At what market level will you liquidate if your thesis proves incorrect? Establish this threshold in advance to prevent emotion-driven choices.
After Each Market Resolves
- Record everything: Document the settlement date, market identifier, your forecast percentage, the price at which you entered, the final outcome, and your gain or loss
- Score your calibration: Did predictions you rated at 70% confidence actually come true roughly 70% of the time?
- Categorize by market type: Do your returns vary significantly across different domains—such as geopolitical, digital assets, or athletic events?
- Review your losers honestly: Did a flawed analytical approach lead to the loss, or was it simply an unlucky outcome despite sound reasoning?
Weekly Review Routine
- Verify all open positions and cumulative returns
- Compute Brier scores across rolling 30-day and 90-day windows
- Examine the schedule for forthcoming pivotal moments (central bank announcements, ballot initiatives, significant economic reports)
- Pinpoint any recurring patterns or tendencies in your recent activity
- Adjust your portfolio's sector or asset allocation if warranted
FAQ
- How often should I review my prediction market performance?
- A weekly cadence works best for the majority of participants. Reviewing every day tends to encourage excessive trading; waiting a full month risks missing the chance to make important adjustments.
- What software should I use to track prediction market trades?
- PolyGram's integrated portfolio management system provides a solid foundation. For more granular reporting, export your transaction log as CSV and process it through spreadsheet software or programming languages like Python.
- How many markets should I research before entering each week?
- Depth of analysis matters far more than breadth. Conducting rigorous research on 3-5 carefully selected markets typically yields superior results than conducting superficial reviews across dozens.
