How to Build a Simple Polymarket Trading Plan

A trading plan is a written answer to the questions you will face when money is on the line. What do you trade? How much do you risk? When do you enter? When do you exit? What makes you stop? Without those answers, every decision becomes an emotional judgment, and the market is very good at exploiting emotion.

A useful Polymarket plan fits on one page. It does not need a forecast for every event. It needs a repeatable process that you can follow for a quarter and then evaluate.

Start with a niche, not a watchlist

Beginners often follow every market on the homepage. That produces shallow knowledge and constant distraction. A better approach is to choose one category for the first quarter: a sport, a political calendar, a macro data series or a crypto asset.

The niche should meet three conditions:

• you already follow the information source;
• the markets are liquid enough to trade;
• there is a regular calendar of catalysts.

If you cannot name the official source for the outcome, the niche is too vague. The how to find good markets guide explains the screening criteria.

Define your edge in one paragraph

Write a paragraph that starts with: "I expect to make money because..." The answer should be specific. Examples:

• I read the official release before the market reprices.
• I understand the resolution rules better than the headline crowd.
• I can identify when a thin market overreacts to a headline.
• I can copy a proven trader with a compatible risk profile.

If the paragraph is "I think I am good at predicting events," you do not have a plan yet. The 2027 roadmap describes the four legitimate sources of edge.

Set the bankroll and risk limits

Decide how much capital is dedicated to Polymarket. This is money you can lose without changing your life. Then set:

• normal risk per trade: 1% to 2% of the bankroll;
• maximum risk per trade: 5%;
• maximum total open risk: 6% to 10%;
• maximum correlated exposure per event: one position;
• drawdown rule: halve size after 10%, stop after 20%.

The position-sizing guide explains the math. The bankroll management guide explains why the account, not the trade, is the first priority.

Write entry rules

An entry rule should be specific enough that another person could follow it. For example:

• I only trade markets with a spread of three cents or less.
• I only trade when my estimated probability is at least four points above my all-in cost.
• I only trade markets with a resolution source I can verify.
• I do not trade in the first ten minutes after a major news release.
• I do not buy contracts below 10 cents or above 90 cents in the first month.

These rules are filters. They will cause you to miss trades, and that is the point. A plan that says yes to everything is not a plan.

Write exit rules

Exit rules are harder than entry rules because they force you to admit uncertainty. A simple framework:

• Take partial profit when the price reaches your fair value.
• Exit if the thesis is invalidated by new information.
• Exit if the market becomes illiquid.
• Exit before resolution if the remaining upside is small relative to the risk.
• Never hold a position you cannot explain.

The resolution rules guide is part of the exit plan. A market can resolve differently than the headline, and the exit may be slower than expected.

Keep a journal

A plan without a record is a wish. For every trade, write:

• date and market;
• side and price;
• size and percentage of bankroll;
• estimated probability;
• reason for the trade;
• resolution source;
• exit plan;
• result and lesson.

The trading journal guide has a template. Review the journal every week, not every day. Daily review encourages overreaction; weekly review shows patterns.

A one-page template

Use this as a starting point:

Niche: one category, one official source.

Edge: one paragraph explaining why I know something the market does not.

Bankroll: amount I can lose.

Risk: 1.5% per trade, 4% maximum, 8% total open.

Entry: spread, edge, source, size.

Exit: fair value, invalidation, liquidity, resolution.

Stop: halve after 10% drawdown, stop after 20%.

Review: every ten trades, every week.

Records: journal, transaction hashes, tax notes.

Print it or keep it open while trading. The point is to make the rules visible before the emotion arrives.

What to do when the plan fails

Every plan will have a losing streak. The question is whether the loss is within the plan's expected range or a sign that the edge is gone. Review the last 20 trades:

• Did you follow the entry rules?
• Were the losses caused by the market or by a deviation from the plan?
• Has the niche changed?
• Is the spread wider than before?
• Are you still able to explain the edge?

If the process was followed and the losses are within the risk limits, continue with smaller size. If you broke the rules, the problem is the execution, not the market. The how to avoid losing money guide covers the common deviations.

The bottom line

A Polymarket trading plan is not a prediction. It is a set of constraints that keep you in the game while you learn. Choose one niche, write the edge, set the risk, define entry and exit, and review the record. The Polymarket beginner guide and the 2027 roadmap provide the wider context.

If you follow the plan for a quarter and the record does not support the edge, change the plan or stop. That is not failure. It is the plan working.
