AAPL,NVDA) or crypto (e.g.BTC-USD,ETH-USD) in the search bar. - Read your analysis — the 14-stage AI pipeline runs automatically and returns a full signal report within seconds.
- Save to watchlist — create a free account to save up to 3 tickers and receive ELITE signal alerts.
- Upgrade to Pro — unlock the live scanner, executive report, ML confidence scores, and unlimited watchlist.
Signals — Breakout & Crash Tiers
Every analysis produces a directional signal (bullish breakout or bearish crash) rated by conviction tier. Tiers are determined by combining multiple independent evidence sources — not a single indicator.
Highest conviction. All evidence aligns: compression, volume expansion, and ML confirmation. Rare — treat these as high-priority setups.
Two or more strong evidence sources agree. Solid directional bias but not all conditions fully met.
At least one confirmed condition. A valid signal worth monitoring, especially in trending regimes.
Insufficient evidence for a directional call. The model recommends staying neutral.
Breakout vs. Crash signals
Both bullish breakout and bearish crash signals share the same tier system. Direction is always shown alongside the tier (e.g. ELITE BUY or STRONG SELL).
Signal horizons
Each signal includes probability estimates for three forward horizons:
- 1 day — short-term momentum
- 5 day — swing / weekly view
- 21 day — positional / monthly view
The 14-Stage AI Pipeline
When you search a ticker, ChartChest runs a multi-layer analysis stack. Each stage feeds into the next, ensuring the final signal is backed by independent confirmation — not a single indicator.
- OHLCV data fetch — live daily price & volume data loaded for the symbol.
- Feature engineering — 182 technical features computed: RSI, MACD, ATR, Bollinger Bands, ADX, choppiness index, volume z-scores, and more.
- Regime detection — Bayesian classifier determines the current market regime: trending bull, trending bear, sideways, or high-volatility.
- Compression detection — volatility contraction scanned for coiling price action (a classic pre-breakout setup).
- Volume expansion check — unusual volume vs. rolling baseline flags potential institutional activity.
- Dark pool proxy — volume anomaly model estimates unreported institutional flow ahead of FINRA biweekly disclosure.
- Candlestick pattern recognition — key reversal and continuation patterns identified.
- LightGBM ML model — trained on 3+ years of walk-forward validated data, outputs a calibrated probability for the directional move.
- Confidence calibration — isotonic regression applied to raw ML probability to produce well-calibrated confidence (ECE < 6%).
- Cross-sectional ranking — symbol's signal strength ranked vs. its peers and sector.
- Horizon return estimation — expected-return scaling applied per horizon (1D / 5D / 21D).
- Meta-gating — a secondary model gates the signal: if P(profitable) < threshold, output is suppressed to HOLD.
- Signal stacking & tier assignment — all evidence is aggregated; tier (ELITE/STRONG/STANDARD/WEAK) is assigned.
- Executive summary generation — AI synthesises macro context, scenario projections (bull / base / bear / breakout / breakdown), and actionable commentary. Pro
Market Breakout Scanner Pro
The scanner pre-computes signals across 500+ symbols (S&P 500 stocks + top-33 crypto) and refreshes every 15 minutes during market hours. Results are ranked by signal tier so you surface ELITE opportunities instantly — without having to search symbol by symbol.
What's included
- All stocks from the S&P 500 universe
- Top-33 crypto assets by market cap
- Sortable by tier, direction, expected return, and confidence
- Filters by asset type (stocks / crypto) and signal direction
Scanner data is computed server-side on a Render cron job — you always see the freshest available signals without any processing delay on your end.

Executive Report Pro
The Executive Report is a full AI deep-dive generated for a symbol on demand. It goes beyond the signal tier to provide:
- Macro & sector context — how the broader market regime affects this symbol
- Signal confluence summary — which pipeline stages agree, disagree, and why
- Scenario projections — bull, base, bear, breakout, and breakdown cases with estimated return ranges per horizon
- Key risk factors — what would invalidate the current signal
- Actionable commentary — plain-English summary of the full analysis
Executive Reports are available for any symbol searchable in the app. Generating a report typically takes 5–15 seconds.
ML Confidence Scores Pro
Every signal shown to Pro users includes a calibrated ML confidence score (0–100%). This is the model's estimated probability that the signal direction will be correct over the signal horizon.
How it's calibrated
Raw LightGBM probability is post-processed with isotonic regression, walk-forward validated across 3+ years of out-of-sample data, and tested against a calibration decile curve. Expected Calibration Error (ECE) is < 6%.
How to use it
- ≥ 70% — high conviction; signal is well-supported by the model
- 55–70% — moderate conviction; worth monitoring
- < 55% — low conviction; treat as informational only
Confidence scores are not a guarantee of returns. They reflect model certainty, not actual future performance.

FAQ
Is ChartChest financial advice?
No. ChartChest is an informational and educational tool. All signals are generated by automated models and may contain errors. Never make investment decisions based solely on any automated system. Consult a qualified financial advisor before trading.
How often is data updated?
Price and feature data is updated daily (end-of-day). The market scanner refreshes every 15 minutes. On-demand analyses fetch the latest available data when you search.
What symbols are supported?
Any symbol available via Yahoo Finance is supported for on-demand analysis — that covers U.S. stocks, ETFs, and major crypto pairs (e.g. BTC-USD, ETH-USD, SOL-USD). The live scanner covers 500+ pre-computed symbols including the full S&P 500 and top-33 crypto assets.
How accurate are the signals?
Out-of-sample (2025) performance across 20 symbols: avg AUC 0.562, walk-forward win rate 61% (isotonic calibrated). AAPL 2026 holdout AUC 0.705. All metrics are strict OOS — training cutoff is end of 2024. Past performance does not guarantee future results.
Can I cancel my Pro subscription?
Yes. Cancel any time from your account settings. You keep Pro access until the end of your current billing period. No prorated refunds for partial months.
The app is slow on first load — is that normal?
Yes, for the first request after a period of inactivity. ChartChest runs on Render's free tier which cold-starts after ~15 minutes of idle time. Subsequent requests are fast. Pro users experience fewer cold starts due to higher activity volume.
How do I contact support?
Email support@chartchest.com. We aim to respond within 1 business day.
