Overview

The BMTM Session Score is an outcome-focused evaluation system optimized for automated grid execution. Unlike behavioral-focused scoring systems, this model recognizes that in automated trading, the operator's role is to commence the command and allow the system to operate—not to manage individual trade decisions.

The composite score ranges from 0 to 100 and is derived from three weighted indices measuring extraction quality, operational efficiency, and risk containment. Tilt Engine alignment provides an additional efficiency modifier for directional intelligence tracking.

Composite Formula
COMPOSITE = (Extraction × 0.40) + (Efficiency × 0.30) + (Risk × 0.30)

III
The Three Indices
Extraction Index
40%

Measures profitability against Designed Daily Extraction (DDE) and per-cycle efficiency against Designed Cycle Yield (DCY). Capped upside prevents luck from dominating. Both values are configurable in the Input tab.

Net P/L vs DDE Bands (75% of index)
DDE = configurable (default $400)
< $0: scaled penalty (floor 0)
0–0.25× DDE: 40 | 0.25–0.75× DDE: 70
0.75–1.25× DDE: 92 | >1.25× DDE: 98 (capped)
Expectancy vs DCY Bands (25% of index)
DCY = configurable (default $16.55)
< $0: 0 | 0–0.6× DCY: 50
0.6–1.1× DCY: 85 | >1.1× DCY: 100
Efficiency Index
30%

Measures fee discipline and edge quality. Fee tiers set harsher than reality to train the system to fear fees before you emotionally feel them.

Base Score: 50
Fee Ratio Component (Net ÷ Gross)
Target ratio: 94.6% ($16.55/$17.50)
> 90%: +25 | > 80%: +18 | > 70%: +8 | > 60%: +0 | ≤ 60%: -15
Gross positive, Net negative: -25
Profit Factor Component
> 2.5: +18 | > 2.0: +15 | > 1.5: +10 | > 1.2: +5 | > 1.0: +0 | ≤ 1.0: -12
Tilt Alignment Component
Aligned + Profitable: +5 | Aligned + Unprofitable: 0
Counter + Profitable: 0 | Counter + Unprofitable: -5
Risk Control Index
30%

Measures drawdown containment relative to hard deck. Hard deck physics are real on Day 1—no calibration needed.

Base Score: 75
Drawdown Ratio (Max DD ÷ $400 threshold)
< 20% ($80): 100 | < 40% ($160): 88 | < 60% ($240): 72
< 80% ($320): 55 | < 100% ($400): 35 | ≥ 100%: 10
Controlled Session Bonus
Net P/L positive AND Max DD < $150: +6
Hard Deck Breach Penalty
Net P/L < -$400 OR Max DD > $400: -15
IV
Tilt Engine Integration

The Tilt Engine provides a binary directional verdict (Long/Short) for each session. The Session Score tracks alignment between this verdict and actual execution bias to measure capital deployment efficiency.

Verdict Execution Outcome Modifier Display
Long Long Profitable +5 ALIGNED ✓
Long Long Unprofitable 0 ALIGNED
Long Short Profitable 0 COUNTER
Long Short Unprofitable -5 COUNTER ✗
Any Mixed Any 0 —

The alignment modifier is intentionally light-touch. The grid is designed to be direction-agnostic (Demon VI neutralization), but deploying capital with the tilt is more efficient. This metric tracks Tilt Engine accuracy over time without over-penalizing counter-directional execution.

Data Sources

The parser extracts metrics from session performance exports. The following fields are recognized:

Design Philosophy

The Session Score is built on three principles optimized for automated grid execution:

Outcome Primacy
100% of the score derives from results. In automated execution, the operator's role is to commence the command and allow the system to operate—not to manage individual trade decisions. The grid either worked or it didn't.
Grid-Calibrated Metrics
Scoring logic reflects BMTM grid methodology: fee efficiency is critical (high-frequency execution compounds drag), drawdown is bounded (hard deck is sacred), and expectancy supersedes win rate (many small wins offset few larger losses).
Capital Efficiency Tracking
Tilt Engine alignment measures whether capital was deployed with or against directional intelligence—not to penalize counter-execution, but to track Tilt Engine accuracy over time and optimize deployment strategy.
