Use when developing TradingView indicators. --- # Pine Script Patterns Lightweight scaffold for Pine Script v5/v6 indicator development. ## Before Generating Code ALWAYS use doc-researcher agent or Ref MCP tools to verify: - Current function signatures - v5 vs v6 syntax differences - Deprecated functions ## File Conventions - Version header: `//@version=6` (prefer v6) - License: Mozilla Public License 2.0 - File naming: `LB_*.pine` - Author: Luther Barnum ## Input Group Structure Standard groups (use `group=` parameter): ``` "Feature Toggles" - Master enable/disable switches "VWAP Settings" - VWAP configuration "VWAP Bands" - Standard deviation band settings "Session Settings" - Time-based parameters "Initial Balance" - IB configuration "Opening Range" - OR settings "Pivot Points" - Pivot configuration "Display Options" - Visual settings "Colors" - Color configuration ``` ## Session Defaults - RTH: 9:30 AM - 4:00 PM ET - Timezone: America/New_York - Detection: `time(timeframe.period, sessionString)` ## Resource Limits Set appropriately: - `max_bars_back` - Historical data access - `max_labels_count` - Label objects (default 500) - `max_lines_count` - Line objects (default 500) ## Complete Example Reference: `/Users/lgbarn/Personal/Indicators/Tradingview/LB_RH_MAs.pine` ```pinescript //@version=6 // This Pine Script® code is subject to the terms of the Mozilla Public License 2.0 at https://mozilla.org/MPL/2.0/ // © lgbarn indicator('LB Simple MA Crossover', shorttitle='LB_MACross', overlay=true) // === INPUTS === fastLength = input.int(9, "Fast MA Length", minval=1, group="MA Settings") slowLength = input.int(21, "Slow MA Length", minval=1, group="MA Settings") useLightTheme = input.bool(false, "Light Theme", group="Display") // === CALCULATIONS === fastMA = ta.ema(close, fastLength) slowMA = ta.sma(close, slowLength) // === COLORS === fastColor = useLightTheme ? color.new(#0000FF, 0) : color.new(#00FFFF, 0) slowColor = useLightTheme ? color.new(#FF0000, 0) : color.new(#FF6600, 0) // === PLOTS === plot(fastMA, title="Fast MA", color=fastColor, linewidth=2) plot(slowMA, title="Slow MA", color=slowColor, linewidth=2) ``` ## Key Patterns ### Persistent State (Session Reset) ```pinescript var float cumulativeValue = 0.0 var float sessionHigh = na var float sessionLow = na if ta.change(time("D")) != 0 cumulativeValue := 0.0 sessionHigh := high sessionLow := low ``` ### Session Detection ```pinescript // Check if in RTH session isSessionTime = time(timeframe.period, "0930-1600:23456") // Detect new session start isNewSession = ta.change(time("D")) != 0 // Session with timezone isRTH = not na(time(timeframe.period, "0930-1600", "America/New_York")) ``` ### Theme Colors ```pinescript useLightTheme = input.bool(false, "Light Theme", group="Display") lineColor = useLightTheme ? color.new(#000000, 0) : color.lime fillColor = useLightTheme ? color.new(#000000, 90) : color.new(color.lime, 90) ``` ### VWAP Calculation Pattern ```pinescript var float cumVolume = 0.0 var float cumVwap = 0.0 var float cumVwap2 = 0.0 if isNewSession cumVolume := 0.0 cumVwap := 0.0 cumVwap2 := 0.0 cumVolume += volume cumVwap += volume * hlc3 cumVwap2 += volume * hlc3 * hlc3 vwapValue = cumVolume > 0 ? cumVwap / cumVolume : na variance = cumVolume > 0 ? cumVwap2 / cumVolume - vwapValue * vwapValue : na stdev = variance > 0 ? math.sqrt(variance) : na upperBand = vwapValue + stdev lowerBand = vwapValue - stdev ``` ### Moving Average Patterns ```pinescript // Simple Moving Average smaValue = ta.sma(close, length) // Exponential Moving Average emaValue = ta.ema(close, length) // Weighted Moving Average wmaValue = ta.wma(close, length) // Hull Moving Average hmaValue = ta.hma(close, length) ``` ## Error Handling Patterns ### Check for NA values ```pinescript // Use nz() to replace NA with default safeValue = nz(calculatedValue, 0.0) // Check if value is valid before use if not na(vwapValue) plot(vwapValue, color=color.blue) ``` ### Validate inputs ```pinescript // Ensure slow > fast validatedSlow = math.max(slowLength, fastLength + 1) ``` ### Handle division by zero ```pinescript divisor = high - low result = divisor != 0 ? (close - low) / divisor : 0.5 ``` ### Check bar history ```pinescript // Ensure enough bars for calculation if bar_index >= length - 1 // Safe to calculate value = ta.sma(close, length) ``` ### Runtime errors (v6) ```pinescript if period < 1 runtime.error("Period must be >= 1") ``` ## Trading Context - Focus: /ES, /NQ futures - Timeframe: 5-minute - Key concepts: VWAP+1SD, TWAP, IB, Classic Pivots - Approach: Institutional over retail patterns ## External Libraries Available imports: - `import jmosullivan/SessionVolumeProfile/12 as SVP` - `import jmosullivan/Session/5 as Session` ## Documentation Sources Use Ref MCP to search: - TradingView Pine Script Reference - Pine Script User Manual
