What separates traders who generate steady returns from those treading water or facing losses typically hinges on methodology and discipline rather than forecasting ability alone. This guide outlines the core disciplines that successful market participants employ on a regular basis.
Before Entering Any Position
- Articulate your edge: What insight do you possess that the broader market lacks? Commit this to a single sentence prior to initiating any trade.
- Check the spread: Does the gap between bid and ask prices remain tight enough that your advantage justifies the cost of execution?
- Assess liquidity: Will you be able to unwind this holding at a favourable price if circumstances demand it? Examine the depth of available orders.
- Set your probability independently: Develop your forecast in isolation before examining what the market is pricing to sidestep anchoring effects.
- Calculate position size: Apply the half-Kelly framework. Never exceed 5% of total capital in any single trade regardless of confidence level.
During Position Management
- Update on new information: Following significant developments (speeches, economic data, announcements), reassess your odds and determine whether to increase, maintain, or reduce exposure.
- Don't check obsessively: Day-to-day price swings represent random variation rather than signal. Monitor holdings once daily for markets with extended timeframes.
- Pre-define your exit criteria: At what level will you cut losses if the market moves against you? Establish this threshold beforehand to prevent impulsive choices.
After Each Market Resolves
- Record everything: Timestamp, venue, your forecast, entry price, final outcome, gains or losses
- Score your calibration: Did your 70% predictions pan out roughly 70% of the time across your sample?
- Categorize by market type: Do your results vary between geopolitical, digital asset, and athletic prediction markets?
- Review your losers honestly: Did flawed reasoning lead to this loss, or was the approach sound despite an unfavourable result?
Weekly Review Routine
- Reconcile all holdings and net returns
- Compute rolling 30-day and 90-day Brier scores
- Survey the week ahead for scheduled announcements (central bank decisions, electoral contests, significant indicators)
- Spot any recurring patterns or tendencies in your recent activity
- Adjust your portfolio mix as conditions warrant
FAQ
- How often should I review my prediction market performance?
- A weekly cadence works best for the majority of participants. Reviewing daily encourages excessive trading; reviewing monthly delays necessary adjustments.
- What software should I use to track prediction market trades?
- PolyGram's integrated portfolio management system provides a solid foundation. For deeper insights, export your transaction log as CSV and process it through Excel/Google Sheets or Python.
- How many markets should I research before entering each week?
- Depth of analysis outweighs breadth. Conducting rigorous due diligence on 3-5 opportunities yields superior returns compared to superficial examination of 20.
