Backtesting & Strategy Development

How to Build a Trading Plan

A trading plan is a written document specifying which markets you trade, which setups you take, how you size and limit risk, daily routines, and how you review performance against defined KPIs.

What Sections Belong in a Trading Plan?

Overview: style, timeframe, account type. Markets and universe: symbols, sectors, exclusions. Setups: entry, stop, target rules with references to strategy docs. Risk: per trade percent, daily max loss, max positions, correlation limits. Schedule: prep, scan, trade, review blocks. Tools: platform, data, backup. Psychology rules: breaks after losses, no trading when tired. KPIs and review: weekly metrics, monthly deep dive. Contingencies: platform outage, halts, news blackouts. One plan per account if styles differ.

Keep the plan short enough to read pre-market daily—verbosity guarantees it will not be used.

How Do You Connect the Plan to Backtested Strategies?

Each setup in the plan should map to a backtested or paper-validated strategy version. Include expected win rate, profit factor, and drawdown ranges so live divergence is measurable. Position sizing formula matches backtest. If plan allows discretionary filter, define it—otherwise backtest is invalid comparison. Plan states max trades per setup per day from backtest frequency analysis. Trading plan is deployment layer for development work—not separate fiction.

Link each setup to its strategy version number so rule changes in backtests trigger plan updates.

What Risk Rules Must Be Non-Negotiable?

Per trade risk cap—typically half to two percent of equity. Daily loss stop—stop trading when hit. Weekly loss optional circuit breaker. Max leverage and margin use. No averaging down unless explicitly in setup rules. No increasing size after wins without plan amendment. Hard stops on every trade. Written consequences if rules broken—end session, reduce next day size. Non-negotiable means you actually stop; plan without enforcement is wishful.

Set daily loss limit in the broker when possible—software enforcement beats willpower at 2 p.m.

What Routines Make the Plan Executable?

Pre-market: scan, watchlist, news check, plan read. Open: execute only A setups. Midday: journal and KPI tick. Close: flatten if day strategy, log trades. Evening: review charts of mistakes winners equally. Weekly: KPI versus backtest. Monthly: strategy health, one improvement target. Routines turn plan sections into calendar blocks. Missing routine equals drifting discretionary.

Block the evening review on your calendar—sessions without review repeat the same errors.

How Often Should You Update the Plan?

Minor clarifications anytime with version note. Material changes—new setup, risk increase—only after backtest or thirty paper trades. Emergency changes after blowup require cool-off period and written post-mortem. Annual full rewrite review. Plan is living but not volatile. Store signed PDF or committed doc. Building a trading plan completes the path from idea to professional habit.

Date every revision—comparing live results to the wrong plan version invalidates KPI reviews.
