# Discretionary Strategy Playbooks

Build a repeatable setup description with measurable exclusions.

Use this workbook alongside the course. Write your answers before opening the solutions. Practical work is self-reviewed; scored knowledge checks are in the Academy.

## 1. Setup specification

### Context conditions

Context describes the conditions under which a setup is considered, such as a defined range or trend state. Use observations that can be recorded at the time. Context should narrow the question, not become a vague justification added afterward.

### Entry trigger

An entry trigger is a specific event that makes an order eligible. State the price stream, interval and whether confirmation requires a close. Separate signal time from order submission and fill time.

### Invalidation

Invalidation describes when the idea no longer satisfies its premise. A protective order implements part of that plan but may fill differently from its trigger. Record both the analytical condition and execution behavior.

### Time-based expiry

Expiry ends eligibility when a setup has not entered within a specified window or relevant conditions change. A stale working order can create exposure after the original context has disappeared, so cancellation rules belong in the playbook.

### Worked example

A breakout setup requires a completed bar above a reference level. The bar temporarily trades above but closes below. Under that rule there is no confirmed trigger, even if an intrabar chart looked promising.

### Independent exercise

Write the context, trigger, invalidation and expiry for a hypothetical setup without using words such as obvious or strong unless defined numerically or procedurally.

## 2. Trade management

### Initial protection

Initial protection should reflect the stated invalidation and affordable exposure. Compute quantity from the chosen assumptions before entry. Moving protection farther away solely to avoid recognizing a loss changes the original risk decision.

### Target logic

A target is a planned exit condition, not a promised outcome. Define whether it is a fixed distance, a reference area or another observable rule. Costs and actual fill availability affect realized reward-to-risk.

### Trailing rules

Trailing rules need a precise update schedule and monotonicity convention where applicable. A backtest must not use an intrabar high to tighten a stop before that high was observed. The price path matters when both updates and triggers occur within one bar.

### Partial exit accounting

Partial exits change remaining quantity and realized P&L. Record every execution and cost, then calculate the whole trade consistently. A favorable first exit does not determine the result of the remaining exposure.

### Worked example

Two units enter at 100. One exits at 102 and one at 99, multiplier one and no costs. Total gross P&L is 2−1 = 1, not 2. The first partial exit is only part of the trade.

### Independent exercise

Repeat with total costs of 0.6 and explain what belongs in the final trade record.

## 3. Exclusions

### Event conditions

Event exclusions should specify which information or execution conditions invalidate the study assumptions. A blanket description such as avoid news is ambiguous unless the relevant events and time windows are defined.

### Spread limits as a hypothesis

A spread threshold can be a research hypothesis about feasibility. Record how spread is observed and whether order size matters. Select the threshold before evaluating results rather than excluding costly losses afterward.

### Missing data

Missing required data should produce an unavailable decision, not an invented input. A playbook must define whether it waits, cancels or remains inactive when the necessary observation cannot be established.

### Conflicting exposure

Conflicting exposure includes multiple positions driven by the same risk factor. Assess the account-level plan before adding a setup that looks independent on a separate chart. Different labels do not guarantee diversified losses.

### Worked example

A learner excludes every losing trade whose spread was high, but keeps winners from the same conditions. This is an outcome-dependent filter, not a valid implementation rule.

### Independent exercise

Define a symmetric spread exclusion that can be applied before entry to winners and losers alike. State what data must be retained to verify it.

My inputs and assumptions:

Evidence that would change my conclusion:


## 4. Review

### Store before-and-after evidence

Store a before-entry record with context, trigger and planned risk, followed by the actual result. A post-trade screenshot alone can hide what was visible when the decision was made.

### Classify valid losses

A valid loss follows the rules and loses within the observed execution process. It belongs in the sample. Calling every loss a mistake prevents honest estimation of the strategy's outcome distribution.

### Separate rule changes from execution errors

Separate strategy changes from execution errors. A rejected order or incorrect size is not the same issue as an eligible setup that loses. Different problems require different corrective actions and evaluation records.

### Compare playbooks net of costs

Compare playbooks using the same accounting and sample conventions. Net results, exposure, drawdown and uncertainty matter alongside win rate. A method with more winners can still have worse average losses and lower net expectancy.

### Worked example

Playbook A wins 60% with average win 1 and average loss 2. Before costs, expectancy is 0.6×1−0.4×2 = −0.2. A high win rate alone does not establish a favorable result.

### Independent exercise

Calculate expectancy for a playbook winning 40% with average win 3 and average loss 1, then subtract cost of 0.3 per trade.

My inputs and assumptions:

My calculation or decision:

## Course project

Create two contrasting playbooks and replay them on a reserved chart sample.

### Self-review rubric

- Concepts and reasoning: 25%
- Calculations, data and evidence: 30%
- Process and risk controls: 25%
- Limitations and communication: 20%

Record one correction and one next practice task. This rubric is not automatically graded.

## Worked solutions

### Exercise 1

A valid specification lets another learner classify the same observations. It identifies exactly what data is needed and when. The result is a testable hypothesis, not evidence that the setup will make money.

### Exercise 2

Net P&L is 0.4. The record includes both exit quantities and prices, their times and the allocated costs. Reporting only the favorable exit would overstate performance.

### Exercise 3

Specify the measurement source, time, size convention and threshold before outcomes are known. Retain the observed spread and eligibility decision for every candidate, including excluded cases.

### Exercise 4

Gross expectancy is 0.4×3−0.6×1 = 0.6. Net expectancy under the stated cost is 0.3. These are sample assumptions, not guaranteed future probabilities.
