Chart Types

Stratosfi supports 6 chart types. Switch between them using the chart type selector dropdown in the toolbar.

Type	Description
Candles (default)	Traditional candlestick chart showing open, high, low, and close
Bars	OHLC bar chart — same data as candles but rendered as horizontal ticks
Hollow Candles	Green hollow body = close > open (bullish), red filled body = close < open (bearish). Hollow candles make it easier to see the relationship between consecutive candles
Line	Simple line chart connecting closing prices. Cleanest view for identifying trends
Area	Line chart with a filled area below, emphasizing the overall price trend
Heikin Ashi	Modified candlesticks that average price data to filter noise. Heikin Ashi candles smooth out fluctuations, making trends easier to identify. Green candles with no lower wick indicate a strong uptrend; red candles with no upper wick indicate a strong downtrend

The active chart type is remembered per symbol and persists across sessions. When a non-default type is selected, the chart type selector highlights in amber.

Candlestick Basics

Each candlestick represents one time period (1 minute, 5 minutes, 1 hour, 1 day, etc.) and shows four data points:

• Open — the price at the start of the period
• Close — the price at the end of the period
• High — the highest price during the period
• Low — the lowest price during the period

Green candles mean the close was higher than the open (price went up). Red candles mean the close was lower than the open (price went down).

The thick body shows the range between open and close. The thin lines (wicks/shadows) show the high and low.

Time Frames & Resolution

Date Range Selector

Use the date range buttons above the chart to control how much history is displayed:

Range	Default Resolution	Best For
1D	2 minutes	Intraday scalping, day trading
5D	15 minutes	Short-term swing setups
1M	1 day	Swing trading
3M	1 day	Position trading
6M	1 day	Medium-term trend analysis
YTD	1 day	Year-to-date performance
1Y	1 week	Long-term trend analysis
5Y	1 month	Multi-year investing

Custom Date Range

For precise control, click the Custom button to enter specific start and end dates. Type dates in YYYY-MM-DD format and the chart fetches exactly that range.

Resolution Selector

Each date range supports multiple resolutions (candle intervals). Click the resolution dropdown next to the date range buttons to switch between available intervals:

• 1D range: 1m, 2m, 5m, 15m, 30m, 1h
• 5D range: 2m, 5m, 15m, 30m, 1h
• 1M range: 5m, 15m, 30m, 1h, 1d
• 3M / 6M range: 1h, 1d
• YTD range: 1d, 1wk
• 1Y range: 1d, 1wk
• 5Y range: 1d, 1wk, 1mo
• Custom range: All resolutions available

The active resolution is highlighted in the toolbar. When you switch date ranges, the resolution automatically adjusts to the best fit for that range.

Technical Indicators

RSI (Relative Strength Index)

RSI measures the speed and magnitude of recent price changes to evaluate whether a stock is overbought or oversold.

• Range: 0 to 100
• Above 70: Overbought — the stock may be due for a pullback
• Below 30: Oversold — the stock may be due for a bounce
• Default period: 14

RSI is a momentum oscillator. It does not predict direction — it signals when a move may be overextended.

How to read it: Look for RSI divergences. If the price makes a new high but RSI makes a lower high, momentum is weakening.

MACD (Moving Average Convergence Divergence)

MACD shows the relationship between two moving averages of a stock's price. It consists of three components:

• MACD Line — the difference between the 12-period and 26-period EMA
• Signal Line — a 9-period EMA of the MACD line
• Histogram — the difference between the MACD line and signal line

Bullish signal: MACD line crosses above the signal line. Bearish signal: MACD line crosses below the signal line.

The histogram makes crossovers easier to spot — when the bars switch from red to green, the MACD is crossing up.

VWAP (Volume Weighted Average Price)

VWAP is the average price weighted by volume throughout the trading day. It resets each day.

• Price above VWAP: Buyers are in control
• Price below VWAP: Sellers are in control

Institutional traders use VWAP as a benchmark. If you buy below VWAP, you got a better-than-average price for the day.

Best used for: Intraday trading. VWAP is most meaningful on 1-minute to 1-hour charts.

SMA (Simple Moving Average)

SMA calculates the average closing price over a specified number of periods.

• SMA 20: Short-term trend
• SMA 50: Medium-term trend
• SMA 200: Long-term trend

When a shorter SMA crosses above a longer SMA, it is called a Golden Cross (bullish). When it crosses below, it is called a Death Cross (bearish).

EMA (Exponential Moving Average)

EMA is similar to SMA but gives more weight to recent prices, making it more responsive to new information.

• EMA 9: Very short-term (popular for day trading)
• EMA 21: Short-term
• EMA 50: Medium-term

EMAs react faster than SMAs to price changes, which means they produce signals earlier but may also produce more false signals.

Bollinger Bands

Bollinger Bands consist of three lines:

• Middle band: 20-period SMA
• Upper band: Middle band + 2 standard deviations
• Lower band: Middle band - 2 standard deviations

The bands expand when volatility increases and contract when volatility decreases.

• Price touching upper band: Stock is trading at the high end of its recent range
• Price touching lower band: Stock is trading at the low end of its recent range
• Band squeeze: When bands narrow significantly, a big move may be coming (breakout signal)

Bollinger Bounce: Price tends to return to the middle band. Touching the lower band in an uptrend can be a buying opportunity.

Adding Indicators to Your Chart

1. Open any stock chart.
2. Click the Indicators button in the chart toolbar.
3. Select the indicators you want to add.
4. Indicators appear as overlays on the chart (moving averages, Bollinger Bands) or in separate panels below (RSI, MACD).

For the full library of 40 indicators, strategies, and overlays, see Chart Plugins.

Multiple Bottom Panels

You can display up to 4 indicator panels below the main chart simultaneously. For example, run RSI, MACD, Volume, and OBV all at once.

• Click Add Panel at the bottom of the chart to add a new indicator panel.
• Each panel can be resized by dragging the divider between panels.
• Click the × on any panel to remove it.

This lets you see momentum, trend, and volume indicators side by side without cluttering the price chart.

Live Chart Mode

Enable real-time streaming updates on your chart by clicking the play button (▶) in the chart toolbar. When active:

• A LIVE badge appears in the top-right corner of the chart with a pulsing red dot
• The current (developing) candle updates in real time via WebSocket
• Price changes are reflected instantly without refreshing
• Click the stop button (■) to pause live updates

Live mode connects to the real-time quote WebSocket feed. It works on any time frame — on intraday charts (1m, 5m, etc.), you will see the current candle form in real time. On daily charts, the last candle updates throughout the trading day.

When to use it: Day trading, monitoring open positions, watching for breakout triggers, or simply keeping a chart up on a second monitor during market hours.

Infinite Historical Scroll

When you scroll left past the beginning of the loaded chart data, Stratosfi automatically fetches older historical data and prepends it to the chart. This lets you scroll back through months or years of price history without changing the date range or resolution.

• Scrolling is seamless — new bars appear as you reach the left edge
• The chart maintains your current view position after loading older data
• Works with all chart types and resolutions
• Drawings and indicators recalculate to include the newly loaded data

When to use it: Zooming out to see longer-term trends without switching from your current resolution, checking how far back a support level holds, or scrolling through years of weekly data to understand a stock's full history.

Drawing Tools

Stratosfi includes 67 drawing tools organized into 8 categories for annotating your charts.

Lines (10 tools)

Trend Line, Ray, Info Line, Extended Line, Trend Angle, Horizontal Line, Horizontal Ray, Vertical Line, Cross Line, Arrow.

Use trend lines to connect swing highs or lows and identify the direction of the trend. Horizontal lines are ideal for marking support and resistance levels.

Channels (4 tools)

Parallel Channel, Regression Trend, Flat Top/Bottom, Disjoint Channel.

Channels define a price corridor. When price breaks out of a channel, it often signals the start of a new trend.

Pitchforks (4 tools)

Andrews' Pitchfork, Schiff Pitchfork, Modified Schiff Pitchfork, Inside Pitchfork.

Pitchforks project support and resistance from three anchor points. The median line acts as a magnet for price.

Fibonacci & Gann (15 tools)

Fib Retracement, Fib Extension, Fib Channel, Fib Time Zone, Fib Speed Fan, Fib Time Extension, Fib Circles, Fib Spiral, Fib Arcs, Fib Wedge, Pitchfan, Gann Box, Gann Fan, Gann Square Fixed, Gann Square.

Fibonacci retracement is the most widely used — it identifies likely support levels during a pullback (38.2%, 50%, 61.8%).

Forecast & Position (5 tools)

Long Position, Short Position, Forecast, Bars Pattern, Projection.

Long/Short Position tools let you visually plan a trade with entry, stop-loss, and target levels, calculating the risk/reward ratio automatically.

Measurement (3 tools)

Price Range, Date Range, Date & Price Range.

Measure the distance between two price points, two dates, or both. Useful for calculating the size of a move or how long a pattern took to develop.

Shapes (10 tools)

Rectangle, Rotated Rectangle, Circle, Triangle, Ellipse, Arc, Path, Polyline, Curve, Double Curve.

Use shapes to highlight chart patterns like head and shoulders, triangles, or flag formations.

Annotations & Markers (16 tools)

Text, Callout, Anchored Text, Note, Price Note, Price Label, Flag Mark, Pin, Comment, Signpost, Table, Brush, Highlighter, Arrow Marker, Arrow Up, Arrow Down.

Add notes, labels, and visual callouts to your chart to document your analysis.

Magnet Mode

When Magnet Mode is enabled (it is on by default), drawing anchor points automatically snap to the nearest OHLC value (open, high, low, or close) of the closest candle. This ensures your drawings align precisely with actual price levels.

Toggle Magnet Mode on or off using the magnet icon in the drawing toolbar.

AI Drawing

The AI can draw directly on your chart. Instead of placing lines manually, describe what you want and the AI creates the annotations for you.

How to Use

1. Open a chart and then open AI Chat.
2. Ask the AI to draw. For example:
   • "Draw support and resistance lines on this chart"
   • "Add Fibonacci retracement from the recent swing low to the high"
   • "Mark the head and shoulders pattern I see around January"
   • "Draw a trend line connecting the last 3 swing lows"
3. The AI analyzes the chart data, determines the correct price levels and positions, and places the drawings on your chart.

[screenshot: ai-drawing]

The AI can create, update, and delete drawings. Ask it to "remove the horizontal lines" or "move the support line to $150" and it adjusts your annotations in place.

What the AI Can Draw

• Horizontal support and resistance lines at key price levels
• Trend lines connecting swing highs or lows
• Fibonacci retracements between significant price points
• Channels, rectangles, and other pattern markers
• Price labels and text annotations

Save & Share Charts

You can save your chart analysis (drawings, indicators, time frame, and configuration) and share it with others.

Saving a Chart

1. Set up your chart with the indicators, drawings, and time frame you want.
2. Click the Save button in the chart toolbar.
3. Give your chart a name (e.g., "AAPL Support Analysis" or "NVDA Earnings Setup").
4. The chart is saved to your account.

Loading a Saved Chart

1. Click the Load button in the chart toolbar.
2. Select from your list of saved charts.
3. The chart restores with all drawings, indicators, and configuration intact.

Sharing a Chart

1. Open a saved chart.
2. Click the Share button.
3. A shareable link is generated.
4. Anyone with the link can view your chart in read-only mode — they see your drawings and analysis but cannot modify them.

Shared charts are interactive: viewers can zoom, pan, and change time frames while your drawings remain visible.

URL Persistence

Chart state is automatically persisted in the URL. When you change the symbol, date range, or resolution, the URL updates so you can bookmark it or share the current view directly.

Why Use This

Visual price analysis is the foundation of trading and investing. Charts let you see what the market is actually doing, not just what the headlines say. Price patterns, volume surges, and indicator signals reveal the collective behavior of every buyer and seller. Whether you are holding for years or trading intraday, charts give you the context you need to make timing decisions with confidence rather than guesswork.

How to Get Started

1. Pick a stock — type any ticker (e.g., AAPL, TSLA, NVDA) in the search bar and click into its chart.
2. Choose your time frame — start with the 1D (daily) chart for a big-picture view, then zoom in to 1h or 5m for finer detail.
3. Add your first indicator — click Indicators and add RSI and SMA 50. These two alone give you momentum and trend context for any stock.
4. Try drawing — select the Horizontal Line tool and click on a support level. Then try a Trend Line connecting two swing lows.
5. Ask the AI — open AI Chat and type "Draw support and resistance on this chart" to see AI-powered drawing in action.

Pro Tips

• Layer your indicators: Combine a momentum indicator (RSI or MACD) with a trend indicator (SMA or EMA) and a volatility indicator (Bollinger Bands). Three different lenses on the same price action reduce false signals.
• Watch for divergences: If NVDA makes a new price high but RSI prints a lower high, momentum is fading. This is one of the most reliable early warning signals across all time frames.
• Use VWAP as your intraday anchor: Institutional traders benchmark against VWAP. If you are day trading and the price is above VWAP, the bias is bullish. Below VWAP, sellers have control. VWAP resets daily, so it is meaningless on weekly or monthly charts.
• Bollinger Band squeezes predict big moves: When the bands contract to their tightest range in weeks, a breakout is coming. The squeeze does not tell you direction, so wait for the breakout candle before committing.
• RSI lies in trends: In a strong uptrend (like NVDA during an AI rally), RSI can stay above 70 for weeks. Do not short a stock just because RSI says "overbought" if the trend is clearly up.
• Save before experimenting: Save your current chart analysis before trying a different time frame or adding new drawings. This way you can always reload your previous setup.
• Use Magnet Mode for precision: Keep Magnet Mode on (the default) when drawing trend lines and Fibonacci levels. Snapping to exact OHLC prices ensures your levels are accurate.
• Let the AI do the tedious work: Instead of manually drawing support and resistance on 10 different stocks, ask the AI to do it. It analyzes the price data and places lines at statistically significant levels.

Common Patterns

"Is AAPL overbought right now?"

Open AAPL's daily chart, add RSI and Bollinger Bands. If RSI is above 70 and the price is riding the upper Bollinger Band, the stock is extended. Check if volume is declining on recent up days — that confirms weakening momentum. If RSI is diverging (lower highs while price makes higher highs), a pullback to the 20-day SMA is likely.

"Golden Cross setup on MSFT"

Add SMA 50 and SMA 200 to MSFT's daily chart. When the 50-day SMA crosses above the 200-day SMA, that is a Golden Cross — a classic bullish signal. Confirm with rising volume on the crossover day and RSI above 50. The opposite (50 crosses below 200) is a Death Cross, which is bearish.

"MACD divergence on TSLA"

Pull up TSLA's daily chart and add MACD. If TSLA's price hits a new high but the MACD histogram is printing smaller bars (or the MACD line makes a lower high), bullish momentum is fading. This divergence often precedes a correction of 5-15%. Use the signal line crossover (MACD crossing below the signal line) as your confirmation to reduce exposure.
