Selectable Time Stoch Quad Oscillator

Just like my other Stochastic oscillator, with the addition of selectable timeframe!

Stoch Quad Oscillator — User Guide
🧠 Overview
The Stoch Quad Oscillator is a multi-timeframe momentum indicator that tracks four independent stochastic %D lines, each with different smoothing and period settings. It helps detect strong bullish or bearish rotational conditions and overbought/oversold extremes across timeframes.

This version includes:

Configurable timeframe (default: 1-minute) using security()

Slope-based rotation detection across four stochastic levels

Background highlights for strong bullish/bearish momentum setups

⚙️ Inputs & Parameters
🕒 Timeframe
Timeframe for Stochastic Calculation

Type: timeframe

Default: "1" (1-minute)

Sets the timeframe on which all stochastic calculations are performed using request.security().

📈 Stochastic Levels
Each stochastic level has its own %K period and %D smoothing:

Level %K Length %D Smoothing Default Label
1 9 3 %D K9 D3
2 14 3 %D K14 D3
3 40 4 %D K40 D4
4 60 10 %D K60 D10

Smoothing Type: Choose between SMA and EMA for the %D line (default: EMA).

📊 Overbought / Oversold Levels
Overbought Level: Default = 80

Oversold Level: Default = 20

Used to highlight all four stochastics being in extreme zones.

🔁 Quad Rotation Detection
Detects high-momentum reversals across all four stochastic levels using slope and aggregate thresholds.

Setting Description
Enable Quad Rotation Enables detection of bullish/bearish multi-level slope convergence
Slope Calculation Bars How many bars back to compare the slope
Slope Threshold Slope required to trigger a sharp rotation
Oversold Quad Level Total %D value across all 4 levels to consider as oversold (default: 90)
Overbought Quad Level Total %D value to consider as overbought (default: 310)
Slope Averaging Method "Simple" or "Weighted" slope averaging across levels
Max Signal Bar Window Future-proof field (not actively used in this version)

🎨 Visualization Colors
Bullish Rotation Highlight: Background color when bullish quad rotation is detected

Bearish Rotation Highlight: Background color when bearish quad rotation is detected

Also includes faint background when all four %D values are simultaneously:

Above the overbought level (deep red)

Below the oversold level (deep green)

📉 Chart Display
✅ Lines Plotted
Four %D lines representing different stochastic timeframes and lengths

Overbought (80) and Oversold (20) horizontal reference lines

🎯 Background Highlights
Light Green: Bullish rotation across all 4 stochastics from oversold zone with strong slope up

Light Red: Bearish rotation across all 4 stochastics from overbought zone with strong slope down

Faint Red/Green: All four stochastics are above or below extreme levels

📌 How to Use
Bullish Setup
All four %D lines are oversold (sum < oversoldQuadLevel)

Average slope across levels is rising above slopeThreshold

Background turns light green — signals potential reversal up

Bearish Setup
All four %D lines are overbought (sum > overboughtQuadLevel)

Average slope across levels is falling below -slopeThreshold

Background turns light red — signals potential reversal down

🚧 Limitations
Uses only %D lines (smoothed K) — raw %K values are not plotted

Assumes valid %D range is [0, 100], clamps values accordingly

Not predictive — signals may lag if settings are too long or slope is too smooth

May repaint when using higher timeframes due to request.security() behavior

🧪 Tips for Power Users
Set timeframe to "5" or "15" to align fast signals with higher-timeframe context

Combine with price action tools (support/resistance, trendlines, candles) for confirmation

Use "Weighted" slope averaging to emphasize longer-period stochastic moves
