Analysis framework

Phase 1 — Chart identification

• Asset / ticker (if visible on chart)
• Timeframe: 1m / 5m / 15m / 1h / 4h / 1D / 1W / 1M
• Chart type: candlestick / OHLC bar / line / Heikin-Ashi / Renko
• Date range visible
• Price scale (left/right), axis values

Phase 2 — Trend analysis

Primary trend (highest visible timeframe):

• Direction: uptrend / downtrend / sideways
• Strength: strong / moderate / weak
• Evidence: higher highs + higher lows (up) | lower highs + lower lows (down)

Moving averages (if visible):

• Identify MA periods if labeled (20, 50, 100, 200)
• Price above/below MAs
• MA crossovers (golden cross / death cross)
• MA slope direction

Trendlines:

• Rising channel, falling channel, horizontal range
• Break of trendline → trend reversal signal

Phase 3 — Key price levels

Support levels (price floor, where buyers stepped in):

• Previous lows that held
• Round numbers (psychological support)
• Gap fills
• State as: Strong / Moderate / Weak (how many times tested)

Resistance levels (price ceiling, where sellers appeared):

• Previous highs
• Previous support turned resistance (flip zones)
• Round numbers

Current price position:

• Distance to nearest support: X%
• Distance to nearest resistance: X%
• Risk/reward if long from current: R:R = support_distance / resistance_distance

Phase 4 — Candlestick patterns (last 5-10 candles)

Common patterns to identify:

Bullish	Bearish	Reversal
Hammer	Shooting star	Doji
Bullish engulfing	Bearish engulfing	Evening/Morning star
Dragonfly doji	Gravestone doji	Harami
Morning star	Three black crows	Spinning top
Bullish marubozu	Bearish marubozu	Inside bar

State: pattern name, location (top/bottom/middle of range), reliability (high/medium/low).

Phase 5 — Technical indicators (if visible)

Volume:

• Above/below average
• Volume on up-days vs down-days (accumulation/distribution)
• Volume spike on breakout = confirmation; low volume = weak signal

RSI (if visible):

• Level: overbought (>70) / neutral / oversold (<30)
• Divergence: price making new high but RSI lower = bearish divergence

MACD (if visible):

• Signal line cross direction
• Histogram expanding/contracting
• Zero-line position

Bollinger Bands (if visible):

• Price at upper/lower band = extended
• Band squeeze = low volatility, breakout incoming

Phase 6 — Chart patterns (broader structure)

Identify if visible:

• Continuation: flag, pennant, wedge, cup & handle, triangle
• Reversal: head & shoulders, double top/bottom, triple top/bottom
• Neutral: rectangle, symmetrical triangle

For each pattern: target price (if pattern completes) = breakout level ± pattern height.
