Technical Analyst

Perform comprehensive technical analysis on any US-listed stock using historical OHLCV data from the Finskills API. Computes trend indicators (SMA/EMA, MACD), momentum oscillators (RSI, Stochastic), volatility bands (Bollinger Bands, ATR), volume analysis, and pattern recognition — then synthesizes a structured trading bias with support/resistance levels.

When to Activate This Skill

Activate when the user:

• Asks for a technical analysis of a stock, index, or ETF
• Mentions RSI, MACD, moving averages, Bollinger Bands, or support/resistance
• Asks "where is the stock heading?" or "should I buy the dip?"
• Requests an entry point, stop-loss level, or price target based on technicals
• Asks about chart patterns (head & shoulders, cup & handle, breakout, etc.)
• Uses terms like "overbought", "oversold", "trend", "momentum reversal"

Indicator Calculations

Use the adjustedClose price series for all calculations.

Trend Indicators

Simple Moving Averages (SMA):

SMA_20 = rolling_mean(close, 20)
SMA_50 = rolling_mean(close, 50)
SMA_200 = rolling_mean(close, 200)

Exponential Moving Averages (EMA):

EMA_12 = EW_mean(close, span=12)
EMA_26 = EW_mean(close, span=26)

Trend Alignment (Bull): Price > SMA_20 > SMA_50 > SMA_200 Trend Alignment (Bear): Price \x3C SMA_20 \x3C SMA_50 \x3C SMA_200

MACD:

MACD_line = EMA_12 - EMA_26
Signal_line = EMA(MACD_line, span=9)
MACD_histogram = MACD_line - Signal_line

• MACD crossing above signal + histogram flipping to positive: Bullish momentum building
• MACD crossing below signal + histogram going negative: Bearish momentum

Momentum Oscillators

RSI (14-period):

gain_t = max(close_t - close_{t-1}, 0)
loss_t = max(close_{t-1} - close_t, 0)
avg_gain_14 = rolling_mean(gain_t, 14)
avg_loss_14 = rolling_mean(loss_t, 14)
RS = avg_gain_14 / avg_loss_14
RSI = 100 - 100 / (1 + RS)

• RSI > 70: Overbought — watch for reversal or consolidation
• RSI \x3C 30: Oversold — potential bounce setup
• RSI divergence vs. price: Strong reversal signal

Stochastic Oscillator (slow %K/%D):

%K = (close - lowest_low_14) / (highest_high_14 - lowest_low_14) × 100
%D = SMA(%K, 3)

• %K crosses above %D from below 20: Bullish
• %K crosses below %D from above 80: Bearish

Volatility Indicators

Bollinger Bands (20-period, 2 standard deviations):

BB_middle = SMA_20
BB_upper = SMA_20 + 2 × STD(close, 20)
BB_lower = SMA_20 - 2 × STD(close, 20)
BB_width = (BB_upper - BB_lower) / BB_middle

• Price at/above upper band: Overextended
• Price at/below lower band: Oversold / potential bounce
• Bandwidth squeezing (\x3C 0.10): Coiling for breakout

Average True Range (ATR, 14-period):

TR = max(high - low, |high - prev_close|, |low - prev_close|)
ATR_14 = rolling_mean(TR, 14)

Use ATR for stop-loss placement: Stop = entry - (1.5 × ATR) for longs

Volume Analysis

Volume Moving Average:

Vol_SMA_20 = rolling_mean(volume, 20)

Volume Confirmation:

• Price up + volume > Vol_SMA_20: Strong bullish conviction
• Price up + volume \x3C Vol_SMA_20: Weak rally, distribution risk
• Price down + volume > Vol_SMA_20: Distribution/capitulation

On-Balance Volume (OBV):

OBV_t = OBV_{t-1} + volume_t  if close_t > close_{t-1}
OBV_t = OBV_{t-1} - volume_t  if close_t \x3C close_{t-1}

OBV rising while price flat/declining: Accumulation signal (bullish) OBV falling while price flat/rising: Distribution signal (bearish)

Support & Resistance Identification

Find key levels from recent price history:

1. Swing Highs/Lows: Price levels that acted as pivots (local max/min within 20-bar window)
2. Round Number Levels: Major psychological levels ($50, $100, $150 etc.)
3. Prior Consolidation Zones: Ranges where price traded sideways for > 5 sessions
4. 200-Day SMA: Acts as major dynamic support/resistance for institutional investors
5. 52-Week High/Low: Key psychological and technical levels

Define 3 support levels (S1 \x3C S2 \x3C current price) and 3 resistance levels (current price \x3C R1 \x3C R2 \x3C R3).

Pattern Recognition

Check for the following patterns in the most recent 60 bars:

Bullish Patterns:

• Cup & Handle: Smooth U-shaped base + small consolidation + breakout above handle high
• Ascending Triangle: Flat resistance + rising support → breakout target = base height
• Double Bottom (W): Two equal lows + breakout above neckline
• Bull Flag: Sharp rally + tight consolidation → continuation target = flag pole height

Bearish Patterns:

• Head & Shoulders: Three peaks (higher center) + neckline break → target = head height below neckline
• Descending Triangle: Flat support + lower highs → breakdown target = base height
• Double Top (M): Two equal highs + breakdown below neckline
• Bear Flag: Sharp decline + tight bounce → continuation target = flag pole height down

Analysis Workflow

Step 1 — Multi-Timeframe Trend Assessment

1. Fetch daily (1Y) and weekly (2Y) data
2. Determine primary trend from weekly chart (SMA_20, SMA_50 slope)
3. Determine intermediate trend from daily chart (SMA_20, SMA_50)
4. Flag agreement or conflict between timeframes

Step 2 — Indicator Synthesis

Compute all 12 indicators; create a signal table:

Compute bullish signal count vs. bearish signal count (weighted).

Step 3 — Support/Resistance Map

Identify and rank 3 support and 3 resistance levels.

Step 4 — Pattern Identification

Check for active patterns in the 60-bar lookback window.

Step 5 — Trade Setup Parameters

• Bias: Bullish / Neutral / Bearish
• Entry Zone: Price range for optimal entry
• Stop-Loss: 1.5× ATR below entry (for longs) or above resistance (for shorts)
• Target 1: First resistance level
• Target 2: Second resistance level (extended target)
• Risk/Reward: (Target1 - Entry) / (Entry - Stop)

Limitations

• Technical analysis describes probability, not certainty; no setup has > 65% win rate historically.
• All indicators are lagging by construction — they confirm existing moves, not predict new ones.
• Patterns are identified algorithmically — manual chart reading by an expert may interpret differently.
• Volume signals may be distorted by options expiration or index rebalancing days.
