1. Execution Latency
Quantifies speed
Millisecond-level measurement of platform responsiveness
Our proprietary Attention Protocol v2.1 is a quantitative framework for evaluating trading platforms through the lens of cognitive friction and execution efficiency.
Version 2.1 Last Updated: March 2026Thesis: Every unnecessary click, confusing UI element, or millisecond of latency is a tax on your cognitive resources. In trading, mental bandwidth is finite—platforms should preserve it, not drain it.
What We Measure:
Our testing methodology consists of three complementary measurement systems:
1. Execution Latency
Quantifies speed
Millisecond-level measurement of platform responsiveness
2. Visual Cognitive Load
Quantifies complexity
Information density and UI friction assessment
3. Psychological Friction
Quantifies resistance
Click-count and decision-point mapping

# Custom Latency Monitornode latency-monitor.js --platform=zerodha --samples=500| Latency Range | Score | Classification |
|---|---|---|
| 0-50ms | 10/10 | Excellent |
| 51-100ms | 8/10 | Good |
| 101-200ms | 6/10 | Acceptable |
| 201-500ms | 4/10 | Slow |
| 500ms+ | 2/10 | Unacceptable |
Platform: Zerodha Kite (March 2026)
In high-frequency scenarios, a 100ms delay across 50 trades per day compounds to 5 full seconds of wasted time. Over a year, that’s 30 minutes of pure latency overhead.
Information Density:
Heatmap Analysis: We use eye-tracking simulation to identify:
Cognitive Load Score = 10 - (Visual Elements / Optimal Threshold)Optimal Threshold = 15 elements per functional screenPlatform: Zerodha Kite - Order Entry Screen
Click-Count Methodology:
How many clicks/actions does it take to complete critical tasks?
Standard Task Set:
| Task | Ideal Clicks | Acceptable | Poor |
|---|---|---|---|
| Market Order | 2-3 | 4-5 | 6+ |
| Stop Loss | 3-4 | 5-6 | 7+ |
| View Balance | 1 | 2 | 3+ |
| Check Positions | 1 | 2 | 3+ |
| Export History | 2-3 | 4-5 | 6+ |
We measure wall-clock time for a trained user to complete each task:
Example: Zerodha Kite
Final Score = ( Execution Latency × 0.35 + Visual Cognitive Load × 0.30 + Psychological Friction × 0.35) × Data Consistency MultiplierData Consistency Multiplier:
Testing Protocol Standards
❌ Subjective preference - Some traders prefer dense UIs
❌ Learning curves - Advanced features may require training
❌ Custom workflows - API traders bypass the UI entirely
❌ Regulatory compliance - Not within our scope
