1. Context & Problem Statement

Traders require intuitive, visual comprehension of future equity path uncertainty and drawdown distribution, alongside dynamic contextual assistance across all dashboard screens.

2. Decision

We implemented a sub-20ms vectorized 1,000-path Monte Carlo bootstrap service in FastAPI returning P5/P50/P95 equity envelopes, rendered responsive SVG risk cones with interactive crosshairs in React 19, and mounted a global floating Trader Intelligence Copilot with keyboard triggers (Ctrl+J) and active asset context binding.

3. Consequences & Trade-Offs

Positive Outcomes

Instant stochastic tail-risk visualization and mathematically bounded Risk of Ruin % probabilities

Seamless contextual quantitative explanations across market, bot, and prediction views

Idempotent React 19 rendering using deterministic Mulberry32 PRNG

Negative / Trade-Offs

Streaming 1,000-path permutations across high-resolution charts requires optimized SVG rendering

Mitigation Strategies

Subsampled area gradients and non-blocking worker threads in FastAPI backend
