Performance Analysis
Trader performance analysis — behavioural KPIs, not just P&L.
Traditional performance analysis stops at win rate, expectancy, and Sharpe. Behavioural performance analysis adds a second dimension: decision quality, discipline drift, and emotional pattern. This page maps the KPIs and where EI ALGOS's TIS plus Decision Score fit.
Two dimensions
Statistical KPIs are only half the picture.
Statistical KPIs — win rate, expectancy, profit factor, Sharpe — describe what happened. Behavioural KPIs — decision quality, plan adherence, drift, emotion — describe why. A trader who only tracks the first dimension gets a lagging report every month with no lever to pull.
The behavioural KPI set
Four numbers that lead P&L.
1) Average Decision Score — how good the decisions are, per trade. 2) Plan adherence — % of trades inside the plan. 3) Emotion Score volatility — how much your state drifts week to week. 4) Trader Intelligence Score — the composite consistency read across months. Together they front-run the P&L report.

FAQ
Common questions.
What is trader performance analysis?
The measurement of a trader's results across statistical KPIs (win rate, expectancy, Sharpe) and behavioural KPIs (decision quality, plan adherence, drift). Behavioural KPIs are leading; statistical KPIs are lagging.
Which KPIs actually matter?
It depends on the strategy and the timescale. For most retail traders, plan adherence and average Decision Score are the highest-signal KPIs because they front-run the P&L numbers.
How is this different from a trading journal?
A journal is the raw log. Performance analysis is what you read out of the log. EI ALGOS automates the read via Decision Score and TIS.
