# A conditional technical thesis

**TA-13 · Technical Analysis · Core**

**Lesson question:** How do you combine evidence without manufacturing certainty?

Original fictional examples; educational writing, not live market data, orders or production approval.

## By the end

- Explain the mechanism in the lesson question.
- Reproduce the worked comparison and recognize its failure case.

**Prerequisites:** TA-01

A checklist should produce a conditional thesis, not a compulsory trade. Write state, location, trigger, invalidation, target and missing evidence. Separate facts from inferred intent.

## Understand the mechanism

Higher highs, a rising average and bullish momentum can all describe the same price sequence. Counting them as independent votes exaggerates confidence. Dealer estimates require their own source and timestamp rather than becoming another unquestioned line.

## Walk through the process

State one favorable branch and one failure branch, then choose an instrument that fits the horizon and volatility view. Recompute risk from the actual available entry. Review process separately from outcome after the event.

## Pause before deciding

Describe what the example actually establishes and what remains unknown. A technical observation supplies context, not an automatic options entry. Contract cost, horizon, liquidity and the consequence of failure still need to match the thesis. Record the contrary branch so a named pattern cannot become an excuse to ignore new evidence.

## A worked example

A fictional entry at 102.20 targets 104 with invalidation 101.50: planned reward/risk is 1.80/0.70≈2.57. If entry worsens to 103.50, unchanged levels produce 0.50/2.00=0.25. The old chart ratio no longer describes the trade.

## Graph: A conditional technical thesis—worked comparison

**Horizontal:** Entry case  
**Vertical:** Planned reward/risk ratio

Fictional data from the written example. The chart organizes the comparison; its shape is not a forecast.

Complete numerical data are embedded in `scripts/technical-analysis/TA-13.js` and displayed as an accessible table in the HTML lesson.

## What would invalidate the reading?

Correlated indicators and idealized fills can manufacture an apparent edge. A stop price is a plan, not a guaranteed execution.

## Check your understanding

### Can the original ratio be reused after the worse fill?

**Answer:** No; it falls to 0.25.

**Why:** Use actual proposed entry, not the chart's attractive historical price.

### What is the critical failure to avoid?

**Answer:** Correlated indicators and idealized fills can manufacture an apparent edge. A stop price is a plan, not a guaranteed execution.

**Why:** Explain this risk before treating the example as a decision rule. A correct calculation does not guarantee a favorable market outcome. **Critical risk check.**

## Takeaway

Return to the question: How do you combine evidence without manufacturing certainty? State the observed facts, the assumptions and the failure condition separately.
