bar color changeThis Pine v5 code allows you to distinguish between candles on the chart. The body/wick/frame of the "live" candle that hasn't yet closed is colored white. When a live candle is present, the body of the immediately preceding candle is colored green with offset = -1. All other candles remain gray (#2e2e2e). plotcandle fixes the wick/frame so that the live and previous candles are selected when following the trend. If there are other conflicting scripts, the most recently added one quickly takes precedence.

Bars pattern MLThis script implements a K-Nearest Neighbors (KNN)-based machine learning model to predict future price movements in financial markets. It analyzes past price action using Euclidean distance and selects the most similar historical patterns to estimate future price changes. Unlike traditional KNN implementations, this approach optimizes distance calculations by maintaining a dynamically updated list of the closest neighbors, ensuring efficient selection without the need for sorting. The model generates a forecasted price trajectory based on incremental predictions, which are visualized on the chart using polylines for better interpretability.

Volume HighlightBar colouring: this indicator is simple but effective, it repaints higher than normal candles a certain colour (by default gold/yellow) it helps to know what are valuable areas to trade around for longs and shorts. Changing the volume multiplier manually helps you to screen volume relevant to the timeframe you are trading on. For example, some charts 1min the best filter/setting would be 12-35 multiplier where others like btc 1-4 hourly, the filter/setting might be 8-12. The key is having only the highest/most relevant 3-4 volume candles showing as they often represent supports and resistances.

WhenWasThePriceAction Bars of largest range (volatility) * see moments of strongest price action immediately * colored & upDown by candle color * amplifier: you see only the bull runs, and subsequent dumps Very nice on the 5 years scale of BITSTAMP:BTCUSD - nothing comparable to 2013 has happened yet. Internals: squared_range = pow(high-low, 2) That is essentially it already. The rest are details: * gauge with (in case of Bitcoin exponentially rising) price * show in red for negative candles * take even higher polynomial (than 2) to show only the very largest values * allow some user input (but there is not much more that can be chosen here.)

FuseKC v6 (Clean + Mode Badge + Flip + Reasons)FuseKC is a confluence-based mode indicator that simplifies decision-making into one of three states: ✅ Modes (one big on-chart badge) BUY MODE → all bullish conditions align (high-probability long environment) SELL MODE → all bearish conditions align (high-probability short environment) STAY OUT → conditions are mixed or incomplete (avoid low-quality trades) The badge updates on the last bar so you always know the current state at a glance. What drives the Mode 1) KC Bias Engine (core direction) Uses a Keltner-style EMA + ATR band on higher timeframes (HTF1 + optional HTF2). Bull bias when price is above the HTF basis Bear bias when price is below the HTF basis 2) Weekly Break + Optional Wait Gate Looks for a break of the previous week high/low. Optionally enforces a 2–3 week wait rule after a big weekly move before allowing new triggers. 3) EMA Filter Optional EMA confirmation: Long favor when price above EMA trend (and optionally stacked above EMA regime) Short favor when price below EMA trend (and optionally stacked below EMA regime) 4) RVOL Filter (your rules) Relative volume filter with clear color meaning: Yellow = weak / dropping volume (below min) Green = good (meets min) Red = best (≥ 1.5× min) 5) ORB (Opening Range Breakout) Builds an ORB range during the selected window after 9:30. Then requires either: Close Break or Wick Break to confirm the direction. Bias Flip Visuals (optional) To make transitions obvious: Arrows print when KC bias flips Background flashes for a user-set number of bars after a flip This helps you notice when the environment changes without guessing. “Why STAY OUT?” Reason List (optional) When the mode is STAY OUT, the script can print a compact reason list (example): No weekly break Weekly wait gate not met EMA filter not aligned RVOL below min ORB still building / no break Chop/range conditions This prevents “random trades” by showing exactly what is missing. Panels + Tiles Right Status Panel summarizes key conditions (Mode, Weekly, EMA, RVOL, ORB, levels, Ripster directions, ATR/DTR, Calls/Puts). Bottom Tiles give quick-glance blocks for volume + Ripster MTF direction. Best Use Use FuseKC as a trade gate + environment filter: Only take longs during BUY MODE Only take shorts during SELL MODE Stand down during STAY OUT (unless you have a separate mean-reversion plan)

ValueAtTime█ OVERVIEW This library is a Pine Script® programming tool for accessing historical values in a time series using UNIX timestamps . Its data structure and functions index values by time, allowing scripts to retrieve past values based on absolute timestamps or relative time offsets instead of relying on bar index offsets. █ CONCEPTS UNIX timestamps In Pine Script®, a UNIX timestamp is an integer representing the number of milliseconds elapsed since January 1, 1970, at 00:00:00 UTC (the UNIX Epoch ). The timestamp is a unique, absolute representation of a specific point in time. Unlike a calendar date and time, a UNIX timestamp's meaning does not change relative to any time zone . This library's functions process series values and corresponding UNIX timestamps in pairs , offering a simplified way to identify values that occur at or near distinct points in time instead of on specific bars. Storing and retrieving time-value pairs This library's `Data` type defines the structure for collecting time and value information in pairs. Objects of the `Data` type contain the following two fields:  • `times` – An array of "int" UNIX timestamps for each recorded value.  • `values` – An array of "float" values for each saved timestamp. Each index in both arrays refers to a specific time-value pair. For instance, the `times` and `values` elements at index 0 represent the first saved timestamp and corresponding value. The library functions that maintain `Data` objects queue up to one time-value pair per bar into the object's arrays, where the saved timestamp represents the bar's opening time . Because the `times` array contains a distinct UNIX timestamp for each item in the `values` array, it serves as a custom mapping for retrieving saved values. All the library functions that return information from a `Data` object use this simple two-step process to identify a value based on time:  1. Perform a binary search on the `times` array to find the earliest saved timestamp closest to the specified time or offset and get the element's index.  2. Access the element from the `values` array at the retrieved index, returning the stored value corresponding to the found timestamp. Value search methods There are several techniques programmers can use to identify historical values from corresponding timestamps. This library's functions include three different search methods to locate and retrieve values based on absolute times or relative time offsets: Timestamp search   Find the value with the earliest saved timestamp closest to a specified timestamp. Millisecond offset search Find the value with the earliest saved timestamp closest to a specified number of milliseconds behind the current bar's opening time. This search method provides a time-based alternative to retrieving historical values at specific bar offsets. Period offset search Locate the value with the earliest saved timestamp closest to a defined period offset behind the current bar's opening time. The function calculates the span of the offset based on a period string . The "string" must contain one of the following unit tokens:  • "D" for days  • "W" for weeks  • "M" for months  • "Y" for years  • "YTD" for year-to-date, meaning the time elapsed since the beginning of the bar's opening year in the exchange time zone. The period string can include a multiplier prefix for all supported units except "YTD" (e.g., "2W" for two weeks). Note that the precise span covered by the "M", "Y", and "YTD" units varies across time. The "1M" period can cover 28, 29, 30, or 31 days, depending on the bar's opening month and year in the exchange time zone. The "1Y" period covers 365 or 366 days, depending on leap years. The "YTD" period's span changes with each new bar, because it always measures the time from the start of the current bar's opening year. █ CALCULATIONS AND USE This library's functions offer a flexible, structured approach to retrieving historical values at or near specific timestamps, millisecond offsets, or period offsets for different analytical needs. See below for explanations of the exported functions and how to use them. Retrieving single values The library includes three functions that retrieve a single stored value using timestamp, millisecond offset, or period offset search methods:  • `valueAtTime()` – Locates the saved value with the earliest timestamp closest to a specified timestamp.  • `valueAtTimeOffset()` – Finds the saved value with the earliest timestamp closest to the specified number of milliseconds behind the current bar's opening time.  • `valueAtPeriodOffset()` – Finds the saved value with the earliest timestamp closest to the period-based offset behind the current bar's opening time. Each function has two overloads for advanced and simple use cases. The first overload searches for a value in a user-specified `Data` object created by the `collectData()` function (see below). It returns a tuple containing the found value and the corresponding timestamp. The second overload maintains a `Data` object internally to store and retrieve values for a specified `source` series. This overload returns a tuple containing the historical `source` value, the corresponding timestamp, and the current bar's `source` value, making it helpful for comparing past and present values from requested contexts. Retrieving multiple values The library includes the following functions to retrieve values from multiple historical points in time, facilitating calculations and comparisons with values retrieved across several intervals:  • `getDataAtTimes()` – Locates a past `source` value for each item in a `timestamps` array. Each retrieved value's timestamp represents the earliest time closest to one of the specified timestamps.  • `getDataAtTimeOffsets()` – Finds a past `source` value for each item in a `timeOffsets` array. Each retrieved value's timestamp represents the earliest time closest to one of the specified millisecond offsets behind the current bar's opening time.  • `getDataAtPeriodOffsets()` – Finds a past value for each item in a `periods` array. Each retrieved value's timestamp represents the earliest time closest to one of the specified period offsets behind the current bar's opening time. Each function returns a tuple with arrays containing the found `source` values and their corresponding timestamps. In addition, the tuple includes the current `source` value and the symbol's description, which also makes these functions helpful for multi-interval comparisons using data from requested contexts. Processing period inputs When writing scripts that retrieve historical values based on several user-specified period offsets, the most concise approach is to create a single text input that allows users to list each period, then process the "string" list into an array for use in the `getDataAtPeriodOffsets()` function. This library includes a `getArrayFromString()` function to provide a simple way to process strings containing comma-separated lists of periods. The function splits the specified `str` by its commas and returns an array containing every non-empty item in the list with surrounding whitespaces removed. View the example code to see how we use this function to process the value of a text area input . Calculating period offset times Because the exact amount of time covered by a specified period offset can vary, it is often helpful to verify the resulting times when using the `valueAtPeriodOffset()` or `getDataAtPeriodOffsets()` functions to ensure the calculations work as intended for your use case. The library's `periodToTimestamp()` function calculates an offset timestamp from a given period and reference time. With this function, programmers can verify the time offsets in a period-based data search and use the calculated offset times in additional operations. For periods with "D" or "W" units, the function calculates the time offset based on the absolute number of milliseconds the period covers (e.g., `86400000` for "1D"). For periods with "M", "Y", or "YTD" units, the function calculates an offset time based on the reference time's calendar date in the exchange time zone. Collecting data All the `getDataAt*()` functions, and the second overloads of the `valueAt*()` functions, collect and maintain data internally, meaning scripts do not require a separate `Data` object when using them. However, the first overloads of the `valueAt*()` functions do not collect data, because they retrieve values from a user-specified `Data` object. For cases where a script requires a separate `Data` object for use with these overloads or other custom routines, this library exports the `collectData()` function. This function queues each bar's `source` value and opening timestamp into a `Data` object and returns the object's ID. This function is particularly useful when searching for values from a specific series more than once. For instance, instead of using multiple calls to the second overloads of `valueAt*()` functions with the same `source` argument, programmers can call `collectData()` to store each bar's `source` and opening timestamp, then use the returned `Data` object's ID in calls to the first `valueAt*()` overloads to reduce memory usage. The `collectData()` function and all the functions that collect data internally include two optional parameters for limiting the saved time-value pairs to a sliding window: `timeOffsetLimit` and `timeframeLimit`. When either has a non-na argument, the function restricts the collected data to the maximum number of recent bars covered by the specified millisecond- and timeframe-based intervals. NOTE : All calls to the functions that collect data for a `source` series can execute up to once per bar or realtime tick, because each stored value requires a unique corresponding timestamp. Therefore, scripts cannot call these functions iteratively within a loop . If a call to these functions executes more than once inside a loop's scope, it causes a runtime error. █ EXAMPLE CODE The example code at the end of the script demonstrates one possible use case for this library's functions. The code retrieves historical price data at user-specified period offsets, calculates price returns for each period from the retrieved data, and then populates a table with the results. The example code's process is as follows:   1. Input a list of periods – The user specifies a comma-separated list of period strings in the script's "Period list" input (e.g., "1W, 1M, 3M, 1Y, YTD"). Each item in the input list represents a period offset from the latest bar's opening time.   2. Process the period list – The example calls `getArrayFromString()` on the first bar to split the input list by its commas and construct an array of period strings.   3. Request historical data – The code uses a call to `getDataAtPeriodOffsets()` as the `expression` argument in a request.security() call to retrieve the closing prices of "1D" bars for each period included in the processed `periods` array.   4. Display information in a table – On the latest bar, the code uses the retrieved data to calculate price returns over each specified period, then populates a two-row table with the results. The cells for each return percentage are color-coded based on the magnitude and direction of the price change. The cells also include tooltips showing the compared daily bar's opening date in the exchange time zone. █ NOTES  • This library's architecture relies on a user-defined type (UDT) for its data storage format. UDTs are blueprints from which scripts create objects , i.e., composite structures with fields containing independent values or references of any supported type.  • The library functions search through a `Data` object's `times` array using the array.binary_search_leftmost() function, which is more efficient than looping through collected data to identify matching timestamps. Note that this built-in works only for arrays with elements sorted in ascending order .  • Each function that collects data from a `source` series updates the values and times stored in a local `Data` object's arrays. If a single call to these functions were to execute in a loop , it would store multiple values with an identical timestamp, which can cause erroneous search behavior. To prevent looped calls to these functions, the library uses the `checkCall()` helper function in their scopes. This function maintains a counter that increases by one each time it executes on a confirmed bar. If the count exceeds the total number of bars, indicating the call executes more than once in a loop, it raises a runtime error .  • Typically, when requesting higher-timeframe data with request.security() while using barmerge.lookahead_on as the `lookahead` argument, the `expression` argument should be offset with the history-referencing operator to prevent lookahead bias on historical bars. However, the call in this script's example code enables lookahead without offsetting the `expression` because the script displays results only on the last historical bar and all realtime bars, where there is no future data to leak into the past. This call ensures the displayed results use the latest data available from the context on realtime bars. Look first. Then leap. █ EXPORTED TYPES Data   A structure for storing successive timestamps and corresponding values from a dataset.   Fields:      times (array) : An "int" array containing a UNIX timestamp for each value in the `values` array.      values (array) : A "float" array containing values corresponding to the timestamps in the `times` array. █ EXPORTED FUNCTIONS getArrayFromString(str)   Splits a "string" into an array of substrings using the comma (`,`) as the delimiter.
