Why You Need a Plan
Without a written plan, every decision is influenced by whatever emotion or headline you encountered most recently. A plan pre-commits you to a specific process, entry criteria, sizing rules, and risk limits.
The difference becomes obvious when you track results. Traders with written plans consistently outperform those making ad-hoc decisions by 15-20% annually across prediction markets. This edge comes from removing emotional reactions to temporary price swings and maintaining consistent evaluation criteria.
Your plan serves as a filter. When Trump's polling numbers shift overnight or a new economic indicator drops, you'll have predetermined criteria for whether this information actually changes your probability estimates. Without this filter, you're reacting to noise instead of signal.
Choosing Your Market Focus
Narrowing to 2-3 categories where you have genuine knowledge beats spreading across everything. The prediction market universe spans politics, economics, sports, entertainment, and crypto. Each requires different information sources and analytical approaches.
Political markets reward understanding of polling methodology, demographic shifts, and electoral mechanics. Economic markets favor macro analysis and Fed communication patterns. Sports markets depend on injury reports and team dynamics. Pick where your existing knowledge creates an advantage.
Consider liquidity patterns too. Political markets see massive volume spikes around debates and major news events, while sports markets maintain steadier flow. Economic prediction markets often have thin order books but wide spreads, creating opportunities for patient traders.
Document your edge in each category. Maybe you're particularly good at identifying when polling averages lag behind demographic changes in swing states. Or you excel at reading Fed communications for policy shifts. Write down what gives you an advantage, because this becomes your hunting ground.
Information Sources and Edge Development
Your analytical process needs consistent information inputs. For political markets, this might include FiveThirtyEight polling averages, early voting data from TargetSmart, and demographic analysis from Catalist. For economic markets, consider Fed speeches, employment data trends, and yield curve movements.
The key is developing proprietary insights from public information. Everyone sees the same polling data, but not everyone understands how late-deciding voters typically break or how turnout models affect different demographics. Your edge comes from processing available information more accurately than the crowd.
Track which information sources actually move your probability estimates versus which just confirm existing views. Many traders consume too much redundant information that doesn't improve their predictions. Focus on sources that genuinely update your priors.
Entry Criteria and Position Management
Your entry criteria should include minimum edge requirements, liquidity thresholds, and timing considerations. A common framework requires at least 5% edge (your probability estimate minus market price), minimum $10,000 daily volume, and at least 30 days until resolution.
Edge calculation matters more than most traders realize. If you estimate 60% probability for an outcome trading at 55 cents, your edge is 5 percentage points. But if your confidence interval is wide, that apparent edge might disappear. Build uncertainty into your estimates.
Liquidity requirements prevent getting stuck in positions. Markets with under $1,000 daily volume can trap you when news breaks and you want to exit quickly. Use Blockcircle's liquidity tracking to identify which contracts maintain consistent order flow.
Time to resolution affects your opportunity cost. Tying up capital for six months in a 2% edge trade rarely beats finding multiple 3% edge trades with monthly resolutions. Factor in your capital velocity when evaluating opportunities.
Sizing Rules That Actually Work
Kelly criterion provides a mathematical foundation for position sizing, but most traders need to reduce the Kelly fraction by 50-75% to account for estimation errors. If Kelly suggests 10% of capital, consider risking 2.5-5% instead.
Maximum position size should rarely exceed 15% of your total capital, regardless of perceived edge. Even seemingly certain outcomes sometimes surprise markets. Brexit passed despite 85% market confidence it would fail. COVID-19 emerged despite pandemic prediction markets showing low probabilities.
Set maximum total deployed capital at 60-80% of your available funds. This preserves dry powder for exceptional opportunities and prevents overextension during drawdown periods. Cash sitting idle feels wasteful, but it's insurance against forced selling during temporary losses.
Consider correlation between positions. Holding multiple Trump-related contracts or several Fed policy bets creates concentrated risk disguised as diversification. Use correlation matrices to ensure your positions actually provide independent exposures.
Risk Management Beyond Position Sizing
Maximum loss per position should be predetermined and absolute. If you're willing to lose $500 on a trade, exit when you hit that level regardless of your conviction about eventual resolution. This prevents small losses from becoming portfolio-damaging events.
Portfolio drawdown limits force systematic risk reduction during losing streaks. Many successful traders halt new positions after 15% portfolio drawdown and reduce existing position sizes by 50%. This prevents the psychological spiral where losses lead to bigger bets trying to recover quickly.
Maximum simultaneous positions depends on your attention capacity and capital base. Most part-time traders struggle to properly monitor more than 8-10 active positions. Full-time traders might handle 20-25, but quality analysis suffers beyond that point.
Track your win rate and average win/loss ratio monthly. Prediction market traders typically see 55-65% win rates with average wins slightly larger than average losses. If your metrics diverge significantly, investigate whether your edge estimates are accurate or your execution needs adjustment.
When to Override Your Plan
Plans need flexibility for genuinely exceptional circumstances. The COVID-19 pandemic created unprecedented prediction market opportunities as traditional models broke down. Brexit referendum night offered massive mispricings as early results conflicted with expectations.
Override criteria should be explicit and rare. Consider allowing plan deviations only for: genuinely unprecedented events affecting multiple markets, clear technical failures creating obvious arbitrage, or situations where you have material non-public information legally obtained.
Document every override decision with reasoning and results. This creates accountability and helps refine your criteria over time. Most overrides lose money because they're driven by FOMO rather than genuine analytical advantages.
Review and Evolution
Review the plan monthly based on results. Adjust focus based on where your analysis produces the best results. Reduce Kelly fraction if drawdowns exceed expectations. The plan should evolve with your experience, but changes should be made during calm review sessions, not in the heat of a trading moment.
Track performance by market category, time horizon, and position size. You might discover that your political predictions excel in primary elections but struggle in general elections. Or that your economic forecasts work better for Fed decisions than employment data. This granular analysis guides future focus areas.
Analyze your biggest wins and losses quarterly. Wins often reveal repeatable analytical advantages worth systematizing. Losses typically show process failures or overconfidence in specific scenarios. Both provide valuable feedback for plan refinement.
Consider using Blockcircle's whale tracking to understand how large traders move markets in your focus areas. Their timing and sizing often reveals information you missed in your analysis.
Your plan should become more specific over time, not more general. As you gain experience, you'll identify precise setups that consistently generate profits. Document these patterns and make them part of your systematic process. The goal is building a repeatable system that works regardless of your daily mood or recent market performance.
