Chart Overview
Not just lines. A read.
Most charting tools give you lines and leave you to figure out what they mean. Spark Charts gives you the same interactive candlestick view — RSI, MACD, Bollinger Bands, moving averages — and then an AI analyst walks you through exactly what the indicators are saying and why it matters.
The AI doesn't just describe what it sees. It frames the analysis around what you're actually trying to do — which is a fundamentally different question depending on whether you're sizing into a new position or deciding whether to take profits.
Tell it your angle.
Looking to enter
Is this a good entry right now, or should you wait for a better level? The AI focuses on entry timing, risk/reward, and what to wait for if the setup isn't there yet.
Looking to exit
You own the stock — should you sell? The analysis focuses on profit-taking zones, stop levels, and the specific signals that would confirm the trend is breaking down.
Chart overview
No position, no bias. Just an honest, comprehensive read of the technical picture: trend structure, momentum state, key support and resistance, and what to watch.
Five lenses. One framework.
Every Spark Charts analysis is built on two years of daily price data with a full suite of computed indicators — the same ones institutional desks use. The AI follows strict interpretation rules for each one, so the output reflects a consistent, research-based framework.
- Trend StructureSMA 20/50/200 with Golden Cross and Death Cross detection. The 200-day SMA is the single most-watched structural level in the market — we tell you where you stand relative to it.
- MomentumRSI (14) with overbought/oversold thresholds, MACD histogram direction (the most important signal most people miss), and Stochastic %K/%D for ranging markets.
- VolatilityBollinger Band width to identify squeeze setups before a big move, and ATR-based stop suggestions that account for the stock's actual daily range — not round numbers.
- Volume & OBVOn-Balance Volume divergence is one of the best leading indicators for accumulation and distribution. We flag it when price and OBV are telling different stories.
- Key LevelsPivot-point derived support and resistance (R1, R2, S1, S2) plotted directly on the chart, plus the AI's plain-English assessment of what each level means for your trade.
Built on decades of established research
The AI doesn't invent interpretation rules — it follows a strict framework defined from the foundational technical analysis literature that professional analysts have relied on for decades:
- ·RSI — J. Welles Wilder Jr. — New Concepts in Technical Trading Systems, 1978
- ·MACD — Gerald Appel — Systems and Forecasts, 1979
- ·On-Balance Volume — Joe Granville — Granville's New Key to Stock Market Profits, 1963
- ·Bollinger Bands — John Bollinger — Bollinger on Bollinger Bands, 1980s
- ·ATR & Volatility Stops — J. Welles Wilder Jr. — New Concepts in Technical Trading Systems, 1978
