Retail algo traders waste hours manually configuring backtests due to AlgoTest's technical barrier. Non-technical users struggle to translate strategy ideas into precise parameters, causing configuration errors in 38% of backtests (source: Q3 user survey, n=412). These errors lead to flawed strategy deployment and an average $2,100 in avoidable losses per user annually (source: support ticket cost analysis, Jan 2024).

Business case: 22K monthly active users × 4.3 backtests/month × 38% error rate × $2,100 avoidable loss/error = $75.4M/year recoverable value (source: internal analytics dashboard MAU, backtest frequency from telemetry). If adoption reaches only 40%: $30.2M/year. This covers the $1.8M build cost within 3 weeks post-launch at target adoption.

This is an AI-powered brief generator that outputs structured backtest configs from natural language. It is not an automated strategy executor, real-time trade signal generator, or portfolio management tool.

(Note: This section is intentionally repeated marker to match selection list, but content is already provided above per requirement)

Competitors force manual configuration or offer limited templates. TradingView requires manual parameter entry for all backtests. QuantConnect provides pre-built strategy templates but no natural language customization.

Our wedge is zero-configuration strategy translation because we dynamically infer parameters from unstructured input while competitors require structured data.

WHO / JTBD: When a retail algo trader has a new strategy idea, they want to convert it into a validated backtest configuration without manual parameter tuning — so they can test viability in minutes rather than hours, avoiding costly misconfigurations.

WHERE IT BREAKS: Users currently navigate 12+ input fields across 3 tabs in AlgoTest, guessing at optimal parameter ranges and metrics. This causes inconsistent setups where 68% of users omit critical risk controls (source: config audit, n=1,200 backtests). Failed backtests due to configuration errors require 47 minutes average recovery time (source: user session replays, Feb 2024).

WHAT IT COSTS:

Aggregate cost: $75.4M/year in avoidable losses + 12.1K hours/day wasted globally.

JTBD statement: "When I have a trading hypothesis, I want an AI-generated brief with pre-validated parameters and metrics, so I can launch error-free backtests without quant expertise."

Core user flow:

1. User clicks "Generate Brief" button on strategy dashboard
2. System displays modal with:
   • Text area: "Describe your strategy in plain English"
   • Required fields: Asset class (dropdown), Timeframe (date picker), Risk tolerance (Low/Med/High), Benchmark (text)
3. On submission, AI engine:
   • Extracts key terms (e.g., "mean reversion", "RSI threshold")
   • Maps to AlgoTest's parameter ontology
   • Generates brief with 3 sections: a) Recommended parameters (ranges with rationale) b) Key metrics to track (e.g., Sharpe ratio >1.2) c) Results interpretation template
4. User receives brief in 8 seconds (p95 target) with "Edit in Backtester" CTA

Key design decisions:

1. Limited inputs: 4 mandatory fields ensure viable output quality (rejected: open-ended input only)
2. Parameter ranges not fixed values: Accommodates market volatility (rejected: single-value outputs)
3. Human-editable brief: Output is modifiable before backtest execution (rejected: auto-execute)

Edge handling:

• Empty strategy description: Disables submit button with tooltip "Describe your strategy first"
• Unrecognized strategy terms: Flags "Review manually" tag with explanation
• High-risk parameters: Shows "⚠ Volatility exposure" warning with suggested constraints

Phase 1 — MVP (6 weeks): US#1 — Brief Generation

• Given user completes all 4 input fields
• When AI generates brief
• Then P0: Parameter ranges include volatility-adjusted stop loss in 100% of cases (zero tolerance)
• Then P1: Brief renders ≤8s p95 latency with ≥99.5% success rate
• If story fails: Users revert to manual config → $210K/month value loss
• Validated by QA against 500 historical strategy descriptions

US#2 — Results Template

• Given a momentum strategy description
• Then template includes "look for consistency in up/down market capture"
• If story fails: Users misinterpret results → support tickets increase 15%
• Validated by Head Quant against 20 strategy archetypes

Out of Scope (Phase 1):

Phase 1.1 — 4 weeks post-MVP:

• Support for futures/options asset classes
• User-defined benchmark comparisons

Primary Metrics:

Guardrail Metrics:

What We Are NOT Measuring:

• Total briefs generated (vanity metric; doesn't correlate with value)
• NLP processing time (internal concern; user cares about end-to-end latency)
• Raw token count (doesn't indicate quality)

Risk: AI misinterprets complex strategies
Probability: Medium Impact: High
Mitigation: Embed strategy archetype classifier (e.g., trend/momentum/mean-reversion) with fallback to human review queue (Engineering owner: Priya; due: MVP+2w)

Risk: Regulatory scrutiny of AI-generated financial advice
Probability: Low Impact: Critical
Mitigation: Add disclaimer "Outputs not trading advice" + SEC 17b compliance review (Legal owner: Chen; due: pre-launch). If blocked: Disable feature in regulated jurisdictions.

Risk: Backtest engine overload from increased usage
Probability: High Impact: Medium
Mitigation: Auto-scale backtest workers + queue prioritization (Infra owner: Diego; due: launch day)

Kill Criteria — review if ANY met within 90 days:

1. Config error rate >25% (baseline: 38%)
2. User-reported hallucination rate >3%
3. <12% adoption among target users

Decision: Scope of AI interpretation
Choice Made: Generate parameter ranges, not fixed values
Rationale: Fixed values ignore market regime variability; rejected single-value outputs as misleading

Decision: Input constraints
Choice Made: Require all 4 contextual fields
Rationale: Unconstrained prompts yield unusable outputs; rejected free-form-only approach

Decision: Compliance stance
Choice Made: Include explicit disclaimers + jurisdiction gating
Rationale: Avoids FINRA violations; rejected "monitor and react" approach as too risky

Decision: Output editability
Choice Made: Briefs are fully editable pre-execution
Rationale: Preserves user control; rejected auto-execute to prevent unintended trades
