MovingAveragesLibrary "MovingAverages" A collection of O(1) numerically stable moving averages that support anchors and fractional lengths up to 100k bars. Pine Script has a robust set of moving averages suitable for a majority of cases, making these alternatives useful only if you need anchoring, fractional lengths, or more than 5k bars. Included are the classic SMA , EMA , RMA , WMA , VWMA , VWAP , HMA , SWMA , Linear Regression , and ATR . The common parameters are: source (float) : Series of values to process. length (simple float) : Number of bars. Optional. anchor (bool) : The condition that triggers a calculation reset. Optional. parity (simple bool) : Sets if built-in function should be used. Optional. Other DSP filter adaptations include One Euro , Laguerre , Super Smoother , and Holt , as well as rate limiting functions such as Smooth Damp and Slew Rate Limiter . ANCHORING This is the libraries first and primary benefit. Akin to the built-in VWAP, anchoring is managed by passing a series bool into the function. For sessional anchoring, the included new_session() returns true on the first bar of intraday sessions, and stabilize_anchor() helps reduce near-anchor volatility. When no length is provided, the series continues indefinitely until a new anchor is set. Values during the warmup period are returned. source = close length = 9.5 anchor = ma.new_session() // Assumes library is imported as "ma" swma = ma.swma(source, length, anchor).stabilize_anchor(source, length, anchor) STREAMING UPDATES Rather than naively using loops to recalculate the whole series on each bar, linear interpolation (aka. "lerping") is used to incrementally update and translate between values. The canonical formula being: a + (b - a) * t. This formula is effectively an EMA, but it's applicable to nearly all averaging equations. Coupling this technique with a circular buffer captures 3 of the 5 benefits this library offers: O(1) computation, fractional lengths, and 100k bars. NUMERIC STABILITY The last benefit is how the library minimizes floating point errors. When possible, Pine Script functions are used for mathematical parity. Otherwise Kahan summation error compensation is used when calculating an average. Not only does this keep custom implementations stable throughout the series, it also helps keep them within 1.0e-10 of the built-in functions. Automatically defaulting to the built-in functions can be disabled by setting parity to false .

SimpleTableA library for when you just want to get a table up with the least hassle. The function `f_drawTableFromColumns()`, is intended to be the simplest possible way to draw a table with the least code in the calling script. Just pass in between one and ten arrays that contain the strings you want to show. Each string array represents one column. That's it. You get a table back. If you want to style the table you can optionally pass colours, size, and whether the table has a header row that should be displayed differently. An example usage section demonstrates creating a three-column table. The function automatically sizes the table based on the number of non-na arrays and the maximum column length. Optional styling parameters cover table position, text size, text alignment, text colour, cell background, header background, header text, and border width. If you don't supply any of these arguments, the table uses some sensible default values. The table is created and updated on the last bar only, with caching to avoid unnecessary redraws. Column shrink detection clears the table only when required, preventing stale cell content. This is not a full-fledged table management library; there are already lots of those published. It is (I believe and hope) the easiest library to use. For example, you don't need to supply a matrix, or a user-defined type full of settings. The library wraps the input arrays into a map, and uses a user-defined type, but internally, so you don't need to worry about it. Just supply one or more arrays with some text. f_drawTableFromColumnArrays(_a_col1, _a_col2, _a_col3, _a_col4, _a_col5, _a_col6, _a_col7, _a_col8, _a_col9, _a_col10, _position, _textSize, _textAlign, _textColor, _cellBgColor, _headerBgColor, _headerTextColor, _hasHeaderRow, _borderWidth)   Renders a table using up to ten string arrays. The table size is derived from the number of non-na arrays and the maximum length across the supplied arrays.   Parameters:      _a_col1 (array) : (array) Column 1 values. Supply na to omit.      _a_col2 (array) : (array) Column 2 values. Supply na to omit.      _a_col3 (array) : (array) Column 3 values. Supply na to omit.      _a_col4 (array) : (array) Column 4 values. Supply na to omit.      _a_col5 (array) : (array) Column 5 values. Supply na to omit.      _a_col6 (array) : (array) Column 6 values. Supply na to omit.      _a_col7 (array) : (array) Column 7 values. Supply na to omit.      _a_col8 (array) : (array) Column 8 values. Supply na to omit.      _a_col9 (array) : (array) Column 9 values. Supply na to omit.      _a_col10 (array) : (array) Column 10 values. Supply na to omit.      _position (string) : (TablePosition) Table position on the chart. Default is top right.      _textSize (string) : (TableTextSize) Text size for all cells. Default is normal.      _textAlign (string) : (TableTextAlign) Horizontal alignment for all cells. Default is left.      _textColor (color) : (color) Text colour for all cells. Default is chart foreground color.      _cellBgColor (color) : (color) Background colour for all cells. Uses a default if na. Default is gray 90%.      _headerBgColor (color) : (color) Background colour for the header row. Uses a default if na. Default is gray 75%.      _headerTextColor (color) : (color) Text colour for the header row. Uses a default if na.      _hasHeaderRow (bool) : (bool) If true, row 0 is treated as a header. Default is true.      _borderWidth (int) : (int) Table border width. Must be non-negative. Default is 1.   Returns: The table object, so the caller can store the table ID if required.

historicalEngine by N&M🇬🇧 English Introduction historicalEngine is a Pine Script library designed for advanced state-based backtesting. It does not test a single strategy, but evaluates full market configurations (trend, structure, momentum, multi-TF context). Each trade is linked to a unique state hash, revealing which conditions truly perform over time. The engine computes professional metrics: PnL, win rate, expectancy, Sharpe, drawdown, reliability. It includes dynamic TP/SL, liquidation logic, early exits, realistic fees and slippage. Built to be modular, extensible, and efficient, it plugs into any indicator. Goal: turn historical data into a statistical trading edge. V1 – a solid foundation for adaptive and data-driven trading systems.

TimeframeAlignTHE PROBLEM THIS LIBRARY SOLVES When you use `request.security()` to get data from a Higher Timeframe (HTF) and try to draw objects like boxes, lines, or labels, they appear at the wrong horizontal position . This is the "floating in space" problem. Why does this happen? The `bar_index` in Pine Script refers to where data was RECEIVED , not where the event OCCURRED . Consider this scenario: • You're on a 5-minute chart • You request 1-hour data for drawing an FVG (Fair Value Gap) • A 1H candle spans 12 chart bars (60min / 5min = 12) • But your code draws at `bar_index - 1` or `bar_index - 3` • The result: your FVG box is only 2-3 bars wide instead of spanning the correct 12-36 bars This library solves that by tracking where HTF bars actually start and end on your chart timeframe. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW TO USE THIS LIBRARY Step 1: Import the Library ``` import ArunaReborn/TimeframeAlign/1 as tfa ``` Step 2: Create a Tracker for Each HTF ``` var tfa.HTFTracker tracker1H = tfa.createTracker("60") ``` Step 3: Update the Tracker Every Bar ``` tfa.updateTracker(tracker1H, "60") ``` Step 4: Use Synced Drawing Functions ``` if tfa.htfBarChanged(tracker1H) tfa.syncedBox(tracker1H, 3, 1, topPrice, bottomPrice, color.new(color.green, 80)) ``` ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ EXPORTED TYPES TimeframePair Stores metadata about the relationship between source and chart timeframes. • sourceTimeframe - The HTF/LTF being compared • chartTimeframe - Current chart timeframe • isHTF - True if source is higher than chart • isLTF - True if source is lower than chart • barRatio - Chart bars per source bar • secondsRatio - Time ratio between timeframes MTFEventData Stores synchronized event data with correct bar positions. • price - Price level of the event • eventTime - Unix timestamp of the event • chartBarStart - Chart bar_index where event's TF bar started • chartBarEnd - Chart bar_index where event's TF bar ended • htfOffset - The HTF offset used • isValid - True if synchronization succeeded HTFTracker Tracks HTF bar boundaries. Create one per timeframe you need to track. • htfTimeframe - The timeframe being tracked • currentStartBar - Where current HTF bar started • currentEndBar - Where current HTF bar ends (provisional) • startHistory - Array of historical start positions • endHistory - Array of historical end positions • lastUpdateBar - Last bar_index when updated • barJustChanged - True if HTF bar changed on this chart bar (set by updateTracker) SyncedBox Managed box with synchronization metadata. • bx - The Pine Script box object • htfTimeframe - Source timeframe • leftHtfOffset / rightHtfOffset - HTF offsets for edges • topPrice / bottomPrice - Price boundaries • extendRight - Auto-extend flag SyncedLine Managed line with synchronization metadata. • ln - The Pine Script line object • htfTimeframe - Source timeframe • htfOffset - Anchor offset • price - Price level (horizontal lines) • isHorizontal - Line orientation • extendRight - Auto-extend flag SyncedLabel Managed label with synchronization metadata. • lbl - The Pine Script label object • htfTimeframe - Source timeframe • htfOffset - Anchor offset • price - Price level • anchorPoint - "start", "end", or "middle" ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ EXPORTED FUNCTIONS ━━ CORE FUNCTIONS ━━ getTimeframeInfo(sourceTimeframe) Analyzes relationship between a source TF and chart TF.

Returns: bar_index or na ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ COMPLETE USAGE EXAMPLES Example 1: FVG Box with Auto-Extend ``` //@version=6 indicator("FVG with Synced Drawing", overlay=true) import ArunaReborn/TimeframeAlign/1 as tfa htfInput = input.timeframe("60", "HTF for FVG") // Create tracker for chosen timeframe var tfa.HTFTracker fvgTracker = tfa.createTracker(htfInput) tfa.updateTracker(fvgTracker, htfInput) // Get FVG data from HTF (confirmed bars with offset) = request.security(syminfo.tickerid, htfInput, [low , high , low > high ], lookahead=barmerge.lookahead_off) // Store managed box var tfa.SyncedBox fvgBox = na // Create synced box when FVG detected if fvgDetected and tfa.htfBarChanged(fvgTracker) fvgBox := tfa.syncedBox(fvgTracker, 3, 1, fvgTop, fvgBot, color.new(color.green, 85), color.green, 1, "FVG", color.white, true) // Extend box to current bar each tick if not na(fvgBox) tfa.updateSyncedBox(fvgBox, true) ``` Example 2: HTF Support/Resistance Lines ``` //@version=6 indicator("HTF S/R Lines", overlay=true) import ArunaReborn/TimeframeAlign/1 as tfa htfInput = input.timeframe("240", "HTF for S/R") // Create and update tracker var tfa.HTFTracker srTracker = tfa.createTracker(htfInput) tfa.updateTracker(srTracker, htfInput) // Get HTF high/low (confirmed with offset) = request.security(syminfo.tickerid, htfInput, [high , low ], lookahead=barmerge.lookahead_off) // Track lines var tfa.SyncedLine resistanceLine = na var tfa.SyncedLine supportLine = na // Create new lines when HTF bar changes if tfa.htfBarChanged(srTracker) resistanceLine := tfa.syncedHLine(srTracker, 1, htfHigh, color.red, line.style_solid, 2, true) supportLine := tfa.syncedHLine(srTracker, 1, htfLow, color.green, line.style_solid, 2, true) // Auto-extend lines each bar if not na(resistanceLine) tfa.updateSyncedLine(resistanceLine, true) if not na(supportLine) tfa.updateSyncedLine(supportLine, true) ``` Example 3: Multiple Timeframes ``` //@version=6 indicator("Multi-TF Boxes", overlay=true) import ArunaReborn/TimeframeAlign/1 as tfa // Create separate tracker for each timeframe var tfa.HTFTracker tracker1H = tfa.createTracker("60") var tfa.HTFTracker tracker4H = tfa.createTracker("240") var tfa.HTFTracker trackerD = tfa.createTracker("1D") // Update ALL trackers every bar (pass the same TF string) tfa.updateTracker(tracker1H, "60") tfa.updateTracker(tracker4H, "240") tfa.updateTracker(trackerD, "1D") // Now use each tracker independently for drawing // Each tracker maintains its own separate boundary history ``` ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ NON-REPAINTING COMPLIANCE To ensure non-repainting behavior, always use this pattern with request.security: ``` = request.security(syminfo.tickerid, htfTimeframe, [value1 , value2 ], // Use offset for confirmed data lookahead=barmerge.lookahead_off) // Never use lookahead_on ``` The ` ` offset ensures you're using the previous completed HTF bar, not the current forming bar. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HISTORY DEPTH PARAMETER The `historyDepth` parameter controls how many HTF bars are tracked: • Default: 500 HTF bars • Maximum: Limited by Pine Script's array constraints • Higher values = more historical accuracy but more memory usage • Lower values = less memory but may return `na` for older offsets Adjust based on your needs: ``` tfa.updateTracker(tracker, 100) // Track 100 HTF bars (light) tfa.updateTracker(tracker, 1000) // Track 1000 HTF bars (heavier) ``` ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ IMPORTANT NOTES 1. One Tracker Per Timeframe : If you need multiple HTFs, create separate trackers for each. The convenience functions (htfBarStartIndex, htfBarEndIndex) only track one TF. 2. Update Every Bar : Always call updateTracker() unconditionally on every bar, not inside conditionals. 3. HTF Only : This library is designed for Higher Timeframe data. For LTF aggregation, use findBarAtTime() for time-based lookups. 4. Drawing Limits : Pine Script has limits on drawing objects. Use box.delete(), line.delete(), label.delete() to clean up old objects. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TROUBLESHOOTING Q: My boxes/lines still appear at wrong positions A: Make sure you're calling updateTracker() on every bar (not inside an if statement) and using the correct htfOffset values. Q: Functions return na A: The htfOffset might be larger than available history. Increase historyDepth or use a smaller offset. Q: Multiple timeframes don't work correctly A: Don't use the convenience functions for multiple TFs. Create separate HTFTracker instances with createTracker() for each timeframe. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CHANGELOG v1 - Initial release • HTFTracker pattern for reliable multi-TF tracking • Synced drawing functions for boxes, lines, labels • Update functions for extending drawings • Convenience functions for simple single-TF use cases

Plan Limit TimerA Pine Script library that helps developers monitor script execution time against TradingView's plan-specific timeout limits. Displays a visual debug table with runtime metrics, percentage of limit consumed, and color-coded status warnings. WHAT THIS LIBRARY DOES TradingView enforces different script timeout limits based on subscription tier: • Basic : 20 seconds • Essential / Plus / Premium : 40 seconds • Ultimate : 100 seconds This library measures your script's total execution time and displays it relative to these limits, helping you optimize indicators for users on different plans. THE DEBUG TABLE When enabled, a table appears on your chart showing: • Plan : The selected TradingView subscription tier • Limit : Maximum allowed execution time for that plan • Runtime : Measured script execution time • Per Bar : Average time spent per bar • Bars : Number of bars processed • % Used : Percentage of timeout limit consumed (color-coded) • Status : OK (green), WARNING (yellow), DANGER (orange), or EXCEEDED (red) HOW IT WORKS The library captures a timestamp at the start of your script using timenow, then calculates the elapsed time at the end. It compares this against the selected plan's timeout limit to determine percentage used and status. Technical Note : Pine Script's timenow variable has approximately 1-second precision. Scripts that execute in under 1 second may display 0ms. This is a platform limitation, not a library issue. For detailed per-function profiling, use TradingView's built-in Pine Profiler (More → Profiler mode in the Editor). EXPORTED FUNCTIONS startTimer() Call at the very beginning of your script. Returns a timestamp. getStats(startTime, plan) Calculates timing statistics. Returns a TimingStats object with all metrics. showTimingTable(stats, plan, tablePosition, showOnlyOnLast) Renders the debug table on the chart. debugTiming(startTime, plan, tablePosition) Convenience function combining getStats() and showTimingTable() in one call. isApproachingLimit(stats, threshold) Returns true if execution time has reached the specified percentage of the limit. getRemainingMs(stats) Returns milliseconds remaining before timeout. formatSummary(stats) Returns a compact single-line string for labels or tooltips. addTimingLabel(stats, barIdx, price, labelStyle, textSize) Creates a color-coded chart label displaying timing statistics. Useful for visual debugging without the full table. Returns the label object for further customization. EXPORTED CONSTANTS • LIMIT_BASIC = 20 • LIMIT_ESSENTIAL = 40 • LIMIT_PLUS = 40 • LIMIT_PREMIUM = 40 • LIMIT_ULTIMATE = 100 EXPORTED TYPE: TimingStats Object containing: • totalTimeMs (float): Total execution time in milliseconds • timePerBarMs (float): Average time per bar • barsTimed (int): Number of bars measured • barsSkipped (int): Bars excluded from measurement • planLimitMs (int): Plan timeout in milliseconds • percentUsed (float): Percentage of limit consumed • status (string): "OK", "WARNING", "DANGER", or "EXCEEDED" HOW TO USE IN YOUR INDICATOR //@version=6 indicator("My Indicator", overlay = true) import YourUsername/PlanLimitTimer/1 as timer // User selects their TradingView plan planInput = input.string("basic", "Your Plan", options = ) // START TIMING - must be first startTime = timer.startTimer() // Your indicator calculations here sma20 = ta.sma(close, 20) rsi14 = ta.rsi(close, 14) plot(sma20) // END TIMING - must be last timer.debugTiming(startTime, planInput) ADVANCED USAGE EXAMPLE //@version=6 indicator("Advanced Example", overlay = true) import YourUsername/PlanLimitTimer/1 as timer planInput = input.string("basic", "Plan", options = ) startTime = timer.startTimer() // Your calculations... sma = ta.sma(close, 200) plot(sma) // Get stats for programmatic use stats = timer.getStats(startTime, planInput) // Option 1: Use addTimingLabel for a quick visual indicator if barstate.islast timer.addTimingLabel(stats, bar_index, high) // Option 2: Show custom warning label if approaching limit if timer.isApproachingLimit(stats, 70.0) and barstate.islast label.new(bar_index, low, "Warning: " + timer.formatSummary(stats), color = color.orange, textcolor = color.white, style = label.style_label_up) // Display the debug table timer.showTimingTable(stats, planInput, position.bottom_right) IMPORTANT LIMITATIONS 1. Precision : Timing precision is approximately 1 second due to timenow behavior. Fast scripts show 0ms. 2. Variability : Results vary based on TradingView server load. The same script may show different times across runs. 3. Total Time Only : This library measures total script execution time, not individual function timing. For per-function analysis, use the Pine Profiler in the Editor. 4. Historical Bars : On historical bars, timenow reflects when the script loaded, not individual bar processing times. USE CASES • Optimization Debugging : See how close your script is to timeout limits • Multi-Plan Support : Help users select appropriate settings for their subscription tier • Performance Regression : Detect when changes increase execution time • Documentation : Show users the performance characteristics of your indicator

ZigZag ATRZigZag ATR Library A volatility-adaptive ZigZag indicator that uses Average True Range (ATR) instead of fixed percentage deviation to detect pivot points. This makes the ZigZag dynamically adjust to market conditions — tighter during low volatility, wider during high volatility. Why ATR instead of Percentage? The standard ZigZag uses a fixed percentage threshold (e.g., 5%) to determine when price has reversed enough to form a new pivot. This approach has limitations: A 5% move means very different things for a $10 stock vs a $500 stock During high volatility, fixed percentages create too many pivots (noise) During low volatility, fixed percentages may miss significant structure ATR-based deviation solves these issues by measuring reversals in terms of actual volatility , not arbitrary percentages. Key Features Volatility-adaptive pivot detection using ATR × multiplier threshold Automatic adjustment to changing market conditions Full customization of ATR length and multiplier Optional line extension to current price Pivot labels showing price, volume, and price change Clean library structure for easy integration Settings ATR Length — Period for ATR calculation (default: 14) ATR Multiplier — How many ATRs price must move to confirm a new pivot (default: 2.0) Depth — Bars required for pivot detection (default: 10) Extend to Last Bar — Draw provisional line to current price Display options — Toggle price, volume, and change labels How to Use import YourUsername/ZigZagATR/1 as zz // Create settings var zz.Settings settings = zz.Settings.new( 14, // ATR length 2.0, // ATR multiplier 10 // Depth ) // Create ZigZag instance var zz.ZigZag zigZag = zz.newInstance(settings) // Calculate ATR and update on each bar float atrValue = ta.atr(14) zigZag.update(atrValue) Exported Types Settings — Configuration for calculation and display Pivot — Stores pivot point data, lines, and labels ZigZag — Main object maintaining state and pivot history Exported Functions newInstance(settings) — Creates a new ZigZag object update(atrValue) — Updates the ZigZag with current ATR (call once per bar) lastPivot() — Returns the most recent pivot point Recommended Multiplier Values 1.0 - 1.5 → More sensitive, more pivots, better for scalping 2.0 - 2.5 → Balanced, good for swing trading (default) 3.0+ → Less sensitive, major pivots only, better for position trading Based on TradingView's official ZigZag library, modified to use ATR-based deviation threshold.
