Chapter 01

Define the evidence before reading the score

Trader question

Which market, timeframe, level, and rule am I testing?

Historical accuracy is only meaningful after the learner names the symbol, exchange, timeframe, level type, lookback window, and tolerance. Changing the rule after seeing the number creates false confidence.

Desk checklist

  • Choose the market and timeframe first.
  • Name the level type before comparing scores.
  • Avoid changing the rule until after the read is written.

Interactive proof

Historical Accuracy controls for exchange, symbol, timeframe, and period

Use the accuracy lab to choose a level behavior, tolerance, and sample window before reading the score.

R2$855
R1$849
CPR top$844
Pivot$841
CPR bottom$839
S1$834
S2$828

Current example price: $843. The lesson asks whether price is accepting inside CPR or rejecting near R1/S1 before acting.

Tested is not respected

A price path touches a pivot level, then two outcomes split: close away means respected, close through means failed.

Chapter 01

Define the evidence before reading the score

Which market, timeframe, level, and rule am I testing?

Historical accuracy is only meaningful after the learner names the symbol, exchange, timeframe, level type, lookback window, and tolerance. Changing the rule after seeing the number creates false confidence.

Historical Accuracy controls for exchange, symbol, timeframe, and period

  • Choose the market and timeframe first.
  • Name the level type before comparing scores.
  • Avoid changing the rule until after the read is written.

Chapter 02

Treat tolerance as part of the rule

Did price actually test the level, or only pass nearby?

Tolerance decides which sessions count as tests. A wider tolerance can create more tested sessions and sometimes a higher-looking respect rate, so the percentage must always be read with the tolerance beside it.

Tolerance parameter behind historical accuracy

  • Read tolerance beside every accuracy number.
  • Notice when near-misses become tests.
  • Use one tolerance consistently before comparing levels.

Chapter 03

Separate tested from respected

Did the level reject price after the test?

Tested means price entered the tolerance band. Respected means the session behavior rejected the level by the close. A high tested count with mixed respect is context, not an automatic level ranking.

Tested, respected, and accuracy columns

  • Count tests before reading accuracy.
  • Count respected sessions separately.
  • Do not treat activity around a level as clean rejection.

Chapter 04

Read the sample before the percentage

Is this percentage built on enough cases to deserve attention?

An 80 percent respect rate from five tests is not the same evidence as 80 percent from fifty tests. The learner should read tested count, period, and fragility before reacting to the percentage.

Period selector, total sessions, and best-performing level badges

  • Read total sessions and tested sessions.
  • Treat tiny samples as prompts for observation.
  • Avoid ranking levels from one dramatic percentage.

Chapter 05

Ask whether the recent past still applies

Has the market regime changed since the sample was built?

Historical behavior can become stale after volatility, event risk, liquidity, or participation changes. CPR summaries are useful context, but narrow, normal, and wide buckets still need current-session confirmation.

CPR statistics and period comparison

  • Check whether recent behavior differs from the full window.
  • Use CPR buckets as context, not a prediction switch.
  • Demote stale evidence after volatility shifts.

Chapter 06

Convert history into a neutral watch note

What should I write after reading the historical panel?

The output is not buy, sell, target, or guarantee language. It is a neutral note that names the level, sample, tolerance, evidence quality, and the next condition that would confirm or invalidate the read.

Historical Accuracy into alerts, confluence, and fresh Pivot Calculator run

  • Name the score and the sample behind it.
  • Name the tolerance used to count tests.
  • Name what would make the historical read stale or wrong.
