Bayesian LHS Parameter Optimizer
Replaces brute-force grid search with Latin Hypercube Sampling and Gaussian Process Expected Improvement (~25-step convergence), complete with Prop Firm Max Drawdown filtering and RoMaD scoring.
Chrome Extension (Manifest V3) · Client-Side Utility
TradingView Strategy Bayesian Optimizer & Overfitting Validator
QuantPulse AI is a local-first Chrome productivity and Pine Script developer tool. Replace exhaustive brute-force parameter sweeps with ~25-step Latin Hypercube + Gaussian Process optimization, 2D plateau heatmaps, multi-timeframe/symbol matrices, commission & slippage stress testing, and copy-ready Pine Script v6 exports.
Client-Side Developer Tool — Not Financial Advice: QuantPulse AI runs strictly inside your local Chrome browser on TradingView. It does not execute live trades, access brokerage accounts, manage funds, or provide investment/trading signals or profit guarantees.

5 Core Implemented Modules
Inspect Every Parameter Before You Trust a Backtest
Switch between the five built-in QuantPulse AI tabs below to review actual screenshots captured inside TradingView.
Module 01 · Optimize Tab
Unlock Full Optimizer (7-Day Free Trial)
Bayesian LHS Parameter Optimizer
Replaces thousands of manual slider adjustments with Latin Hypercube Sampling (LHS) exploration followed by Gaussian Process Expected Improvement (GP-EI) convergence in ~25 steps.
- ✓Prop Firm Drawdown Filtering: Automatically flags parameter sets exceeding your Max Drawdown % threshold.
- ✓Risk-Adjusted Objectives: Rank candidates by
RoMaD (Calmar),Profit Factor, orNet Profit. - ✓Full Quant Telemetry: Displays
SR/SQN,RoMaD,R:R, Win Rate, Expectancy per trade, and Half-Kelly proxy. - ✓One-Click Apply & CSV: Click any ranked row to push parameters back to TradingView or export runs to CSV.
Module 02 · Heatmap Tab
Test Plateau Stability on Your Strategy
2D Parameter Plateau Heatmap
Isolated high-profit parameter spikes frequently collapse out-of-sample. QuantPulse maps adjacent X/Y parameter combinations to score neighborhood stability.
- ✓Solid Plateaus vs. Curve-Fit Islands: Visually differentiates stable regions (
SOLID) from fragile single-cell spikes (ISLAND). - ✓Robustness & DD Pass Rate: Summarizes plateau consistency (0–100) and percentage of tested sets passing your drawdown rule.
- ✓Interactive Cell Inspection: Click any heatmap cell to immediately apply those parameters to your chart.
Module 03 · Sweep Tab
Run Cross-Market Sweeps Locally
Multi-Timeframe & Multi-Symbol Sweep
Verify whether your chosen parameter set generalizes across multiple chart intervals and correlated instruments without manually re-entering settings.
- ✓Timeframes (MTF) Scan: Iterates across selected chart timeframes and records Net Profit, PF, Trades, and Max DD per interval.
- ✓Multi-Symbol Watchlist: Evaluates your active parameter set across watchlists (e.g.,
XAUUSD,BTCUSD,NAS100,EURUSD). - ✓Drawdown Pass Matrix: Quickly flags which symbols or timeframes breach your Max DD limit.
Module 04 · Stress Tab
Stress-Test Before Trusting Results
Commission & Slippage Stress Testing
Zero-commission backtests often mask fragile scalping rules. QuantPulse injects elevated brokerage commission (%) and adverse slippage (ticks) directly into TradingView's Properties tab.
- ✓Pre-Stress vs. With-Cost Comparison: Side-by-side Net Profit, Profit Factor, and Max Drawdown comparison.
- ✓Retention Verdict: Classifies strategies as
ROBUST,SENSITIVE, orFRAGILEbased on retained profit %. - ✓Non-Standard Chart Guard: Warns automatically when running on Heikin Ashi, Renko, Kagi, or Point & Figure charts where synthetic candles distort backtest fills.
Module 05 · Sync, Presets & Pine v6
Start Your 7-Day Free Trial
Pine Script v6 Export & Human-Paced Execution
Auto-detects numeric strategy inputs with instant ±25%, ±50%, and ±100% search bounds, saves local presets, and exports ready-to-paste Pine Script v6 code.
- ✓Pine Script v6 Code Export: Copies formatted
input.int/input.floatparameter lines with benchmark KPI header comments. - ✓Human-Paced Execution: Weibull-distributed delays (2.2s–4.8s) plus cognitive pauses every 15 steps protect TradingView session responsiveness.
- ✓DOM Selector Self-Healing: Uses sanitized structural DOM skeletons (<1.5KB, zero strategy code) to recover smoothly when TradingView updates UI markup.
2D Parameter Plateau Heatmap
Evaluates adjacent parameter neighborhoods to separate broad, repeatable Robust Plateaus from isolated single-point Curve-Fit Islands before locking inputs.
Multi-Timeframe & Multi-Symbol Sweep
Runs automated cross-timeframe and cross-symbol watchlist sweeps, generating a pass/fail drawdown matrix so you can inspect parameter generalization across market regimes.
Commission & Slippage Stress Testing
Stress-tests strategies under realistic brokerage fees and adverse tick slippage directly inside TradingView Properties, plus automatic alerts for Heikin Ashi / Renko / non-standard charts.
Pine Script v6 Export & Human-Paced Local Execution
Generates copy-ready Pine Script v6 input.* parameter definitions and CSV reports, executes parameter changes at randomized human-paced intervals (2.2s–4.8s Weibull jitter + periodic pauses) with dual-track DOM selector self-healing, and keeps 100% of your Pine Script source code and backtest logs strictly local in Chrome (chrome.storage & IndexedDB).
Zero-Config Pine Script Workflow
From Ranked Optimization Table to Copy-Ready Pine Script v6
Once your Bayesian run and Plateau Heatmap confirm a stable parameter zone, copy formatted input.int / input.float defaults straight into your Pine Script v6 editor, or save named parameter presets locally in IndexedDB.
- ✓Detects numeric inputs from TradingView's Strategy Settings dialog automatically
- ✓Supports quick
±25%,±50%, and±100%search range expansion - ✓Saves reusable presets per symbol & timeframe locally in your browser
- ✓Never reads, parses, or transmits your private Pine Script indicator/strategy code
Pine Script v6 · Generated Output Sample
// === QuantPulse Optimized Inputs (XAUUSD · 1D) === // Net Profit: +50.80% | PF: 1.55 | Max DD: 6.25% | SR/SQN: 1.79 atrLength = input.int(12, "ATR Length") superTrendFactor = input.float(1.75, "SuperTrend Factor") trendEmaFilter = input.int(30, "Trend EMA Filter") hardStopLoss = input.float(2.5, "Hard Stop Loss %")
4-Step Workflow

Regulatory & Technical Transparency
Strictly a Client-Side Backtesting Productivity Tool — Not Investment Advice
QuantPulse AI is built for Pine Script strategy authors and systematic researchers who want faster, more disciplined backtest workflows inside TradingView.
Historical backtest simulations—even when validated by plateau heatmaps and friction stress tests—do not predict or guarantee future market performance. Trading involves substantial risk of loss.
Review full terms in our Privacy Policy and Terms of Service & Refund Policy.
- No Live Trade Execution: QuantPulse AI never places orders, triggers webhooks to brokers, or interacts with live exchange accounts.
- No Brokerage Access or Custody: We never ask for brokerage API keys, exchange credentials, or customer funds.
- No Trading Signals or Profit Claims: We provide mathematical parameter search and overfitting diagnostics—not buy/sell signals or financial recommendations.
- Local Strategy Ownership: Your Pine Script source code and optimization datasets remain strictly inside your Chrome browser.
