Replica of TradingView's Backtesting Engine with ArraysHello everyone, Here is a perfectly replicated TradingView backtesting engine condensed into a single library function calculated with arrays. It includes TradingView's calculations for Net profit, Total Trades, Percent of Trades Profitable, Profit Factor, Max Drawdown (absolute and percent), and Average Trade (absolute and percent). Here's how TradingView defines each aspect of its backtesting system: Net Profit: The overall profit or loss achieved. Total Trades: The total number of closed trades, winning and losing. Percent Profitable: The percentage of winning trades, the number of winning trades divided by the total number of closed trades. Profit Factor: The amount of money the strategy made for every unit of money it lost, gross profits divided by gross losses. Max Drawdown: The greatest loss drawdown, i.e., the greatest possible loss the strategy had compared to its highest profits. Average Trade: The sum of money gained or lost by the average trade, Net Profit divided by the overall number of closed trades. Here's how each variable is defined in the library function: _backtest(bool _enter, bool _exit, float _startQty, float _tradeQty) bool _enter: When the strategy should enter a trade (entry condition) bool _exit: When the strategy should exit a trade (exit condition) float _startQty: The starting capital in the account (for BTCUSD, it is the amount of USD the account starts with) float _tradeQty: The amount of capital traded (if set to 1000 on BTCUSD, it will trade 1000 USD on each trade) Currently, this library only works with long strategies, and I've included a commented out section under DEMO STRATEGY where you can replicate my results with TradingView's backtesting engine. There's tons I could do with this beyond what is shown, but this was a project I worked on back in June of 2022 before getting burned out. Feel free to comment with any suggestions or bugs, and I'll try to add or fix them all soon. Here's my list of thing to add to the library currently (may not all be added): Add commission calculations. Add support for shorting Add a graph that resembles TradingView's overview graph. Clean and optimize code. Clean up in a way that makes it easy to add other TradingView calculations (such as Sharpe and Sortino ratio). Separate all variables, so they become accessible outside of calculations (such as gross profit, gross loss, number of winning trades, number of losing trades, etc.). Thanks for reading, OztheWoz

TechnicalRating█   OVERVIEW This library is a Pine Script™ programmer’s tool for incorporating TradingView's well-known technical​ ratings within their scripts. The ratings produced by this library are the same as those from the speedometers in the technical​ analysis​ summary and the "Rating" indicator in the Screener , which use the aggregate biases of 26 technical​ indicators to calculate their results. █   CONCEPTS Ensemble analysis Ensemble analysis uses multiple weaker models to produce a potentially stronger one. A common form of ensemble analysis in technical​ analysis​ is the usage of aggregate indicators together in hopes of gaining further market insight and reinforcing trading decisions. Technical ratings Technical ratings provide a simplified way to analyze financial markets by combining signals from an ensemble of indicators into a singular value, allowing traders to assess market sentiment more quickly and conveniently than analyzing each constituent separately. By consolidating the signals from multiple indicators into a single rating, traders can more intuitively and easily interpret the "technical health" of the market. Calculating the rating value Using a variety of built-in TA functions and functions from our ta library, this script calculates technical ratings for moving averages, oscillators, and their overall result within the `calcRatingAll()` function. The function uses the script's `calcRatingMA()` function to calculate the moving average technical rating from an ensemble of 15 moving averages and filters:  • Six Simple Moving Averages and six Exponential Moving Averages with periods of 10, 20, 30, 50, 100, and 200  • A Hull Moving Average with a period of 9  • A Volume-Weighted Moving Average with a period of 20  • An Ichimoku Cloud with a conversion line length of 9, base length of 26, and leading span B length of 52 The function uses the script's `calcRating()` function to calculate the oscillator technical rating from an ensemble of 11 oscillators:  • RSI with a period of 14  • Stochastic with a %K period of 14, a smoothing period of 3, and a %D period of 3  • CCI with a period of 20  • ADX with a DI length of 14 and an ADX​ smoothing period of 14  • Awesome Oscillator  • Momentum with a period of 10  • MACD with fast, slow, and signal periods of 12, 26, and 9  • Stochastic RSI with an RSI​ period of 14, a %K period of 14, a smoothing period of 3, and a %D period of 3  • Williams %R with a period of 14  • Bull Bear Power with a period of 50  • Ultimate Oscillator with fast, middle, and slow lengths of 7, 14, and 28 Each indicator is assigned a value of +1, 0, or -1, representing a bullish​​, neutral, or bearish​​ rating. The moving​ average​ rating is the mean of all ratings that use the `calcRatingMA()` function, and the oscillator rating is the mean of all ratings that use the `calcRating()` function. The overall rating is the mean of the moving average​ and oscillator ratings, which ranges between +1 and -1. This overall rating, along with the separate MA​ and oscillator ratings, can be used to gain insight into the technical strength of the market. For a more detailed breakdown of the signals and conditions used to calculate the indicators' ratings, consult our Help Center explanation. Determining rating status The `ratingStatus()` function produces a string representing the status of a series of ratings. The `strongBound` and `weakBound` parameters, with respective default values of 0.5 and 0.1, define the bounds for "strong" and "weak" ratings. The rating status is determined as follows: Rating Value Rating Status < -strongBound Strong Sell < -weakBound Sell -weakBound to weakBound Neutral > weakBound Buy > strongBound Strong Buy By customizing the `strongBound` and `weakBound` values, traders can tailor the `ratingStatus()` function to fit their trading style or strategy, leading to a more personalized approach to evaluating ratings. Look first. Then leap. █  FUNCTIONS This library contains the following functions: calcRatingAll()   Calculates 3 ratings (ratings total, MA ratings, indicator ratings) using the aggregate biases of 26 different technical indicators.   Returns: A 3-element tuple: ( [(float) ratingTotal, (float) ratingOther, (float) ratingMA ]. countRising(plot)   Calculates the number of times the values in the given series increase in value up to a maximum count of 5.   Parameters:      plot : (series float) The series of values to check for rising values.   Returns: (int) The number of times the values in the series increased in value. ratingStatus(ratingValue, strongBound, weakBound)   Determines the rating status of a given series based on its values and defined bounds.   Parameters:      ratingValue : (series float) The series of values to determine the rating status for.      strongBound : (series float) The upper bound for a "strong" rating.      weakBound : (series float) The upper bound for a "weak" rating.   Returns: (string) The rating status of the given series ("Strong Buy", "Buy", "Neutral", "Sell", or "Strong Sell").

lower_tf█   OVERVIEW This library is a Pine programmer’s tool containing functions to help those who use the request.security_lower_tf() function. Its `ltf()` function helps translate user inputs into a lower timeframe string usable with request.security_lower_tf() . Another function, `ltfStats()`, accumulates statistics on processed chart bars and intrabars. █   CONCEPTS Chart bars Chart bars , as referred to in our publications, are bars that occur at the current chart timeframe, as opposed to those that occur at a timeframe that is higher or lower than that of the chart view. Intrabars Intrabars are chart bars at a lower timeframe than the chart's. Each 1H chart bar of a 24x7 market will, for example, usually contain 60 intrabars at the ​LTF of 1min, provided there was market activity during each minute of the hour. Mining information from intrabars can be useful in that it offers traders visibility on the activity inside a chart bar. Lower timeframes (LTFs) A lower timeframe is a timeframe that is smaller than the chart's timeframe. This framework exemplifies how authors can determine which ​LTF to use by examining the chart's timeframe. The ​LTF determines how many intrabars are examined for each chart bar; the lower the timeframe, the more intrabars are analyzed. Intrabar precision The precision of calculations increases with the number of intrabars analyzed for each chart bar. As there is a 100K limit to the number of intrabars that can be analyzed by a script, a trade-off occurs between the number of intrabars analyzed per chart bar and the chart bars for which calculations are possible. █   `ltf()` This function returns a timeframe string usable with request.security_lower_tf() . It calculates the returned timeframe by taking into account a user selection between eight different calculation modes and the chart's timeframe. You send it the user's selection, along with the text corresponding to the eight choices from which the user has chosen, and the function returns a corresponding ​LTF string. Because the function processes strings and doesn't require recalculation on each bar, using var to declare the variable to which its result is assigned will execute the function only once on bar zero and speed up your script: var string ltfString = ​ltf(ltfModeInput, LTF1, LTF2, LTF3, LTF4, LTF5, LTF6, LTF7, LTF8) The eight choices users can select from are of two types: the first four allow a selection from the desired amount of chart bars to be covered, the last four are choices of a fixed number of intrabars to be analyzed per chart bar. Our example code shows how to structure your input call and then make the call to `ltf()`. By changing the text associated with the `LTF1` to `LTF8` constants, you can tailor it to your preferences while preserving the functionality of `ltf()` because you will be sending those string constants as the function's arguments so it can determine the user's selection. The association between each `LTFx` constant and its calculation mode is fixed, so the order of the arguments is important when you call `ltf()`. These are the first four modes and the `LTFx` constants corresponding to each: Covering most chart bars (least precise) — LTF1 Covers all chart bars. This is accomplished by dividing the current timeframe in seconds by 4 and converting that number back to a string in timeframe.period format using secondsToTfString() . Due to the fact that, on premium subscriptions, the typical historical bar count is between 20-25k bars, dividing the timeframe by 4 ensures the highest level of intrabar precision possible while achieving complete coverage for the entire dataset with the maximum allowed 100K intrabars. Covering some chart bars (less precise) — LTF2 Covering less chart bars (more precise) — LTF3 These levels offer a stepped ​LTF in relation to the chart timeframe with slightly more, or slightly less precision. The stepped lower timeframe tiers are calculated from the chart timeframe as follows: Chart Timeframe Lower Timeframe Less Precise More Precise < 1hr 1min 1min < 1D 15min 1min < 1W ​2hr​ 30min > 1W 1D 60min Covering the least chart bars (most precise) — LTF4 Analyzes the maximum quantity of intrabars possible by using the 1min ​LTF, which also allows the least amount of chart bars to be covered. The last four modes allow the user to specify a fixed number of intrabars to analyze per chart bar. Users can choose from 12, 24, 50 or 100 intrabars, respectively corresponding to the `LTF5`, `LTF6`, `LTF7` and `LTF8` constants. The value is a target; the function will do its best to come up with a ​LTF producing the required number of intrabars. Because of considerations such as the length of a ticker's session, rounding of the ​LTF to the closest allowable timeframe, or the lowest allowable timeframe of 1min intrabars, it is often impossible for the function to find a ​​LTF producing the exact number of intrabars. Requesting 100 intrabars on a 60min chart, for example, can only produce 60 1min intrabars. Higher chart timeframes, tickers with high liquidity or 24x7 markets will produce optimal results. █   `ltfStats()` `ltfStats()` returns statistics that will be useful to programmers using intrabar inspection. By analyzing the arrays returned by request.security_lower_tf() in can determine:  • intrabarsInChartBar : The number of intrabars analyzed for each chart bar.  • chartBarsCovered : The number of chart bars where intrabar information is available.  • avgIntrabars : The average number of intrabars analyzed per chart bar. Events like holidays, market activity, or reduced hours sessions can cause the number of intrabars to vary, bar to bar. The function must be called on each bar to produce reliable results. █   DEMONSTRATION CODE Our example code shows how to provide users with an input from which they can select a ​LTF calculation mode. If you use this library's functions, feel free to reuse our input setup code, including the tooltip providing users with explanations on how it works for them. We make a simple call to request.security_lower_tf() to fetch the close values of intrabars, but we do not use those values. We simply send the returned array to `ltfStats()` and then plot in the indicator's pane the number of intrabars examined on each bar and its average. We also display an information box showing the user's selection of the ​LTF calculation mode, the resulting ​LTF calculated by `ltf()` and some statistics. █   NOTES  • As in several of our recent publications, this script uses secondsToTfString() to produce a timeframe string in timeframe.period format from a timeframe expressed in seconds.  • The script utilizes display.data_window and display.status_line to restrict the display of certain plots.   These new built-ins allow coders to fine-tune where a script’s plot values are displayed.  • We implement a new recommended best practice for tables which works faster and reduces memory consumption.   Using this new method, tables are declared only once with var , as usual. Then, on bar zero only, we use table.cell() calls to populate the table.   Finally, table.set_*() functions are used to update attributes of table cells on the last bar of the dataset.   This greatly reduces the resources required to render tables. We encourage all Pine Script™ programmers to do the same. Look first. Then leap. █   FUNCTIONS The library contains the following functions: ltf(userSelection, choice1, choice2, choice3, choice4, choice5, choice6, choice7, choice8)   Selects a ​LTF from the chart's TF, depending on the `userSelection` input string.   Parameters:      userSelection : (simple string) User-selected input string which must be one of the `choicex` arguments.      choice1 : (simple string) Input selection corresponding to "Least precise, covering most chart bars".      choice2 : (simple string) Input selection corresponding to "Less precise, covering some chart bars".      choice3 : (simple string) Input selection corresponding to "More precise, covering less chart bars".      choice4 : (simple string) Input selection corresponding to "Most precise, 1min intrabars".      choice5 : (simple string) Input selection corresponding to "~12 intrabars per chart bar".      choice6 : (simple string) Input selection corresponding to "~24 intrabars per chart bar".      choice7 : (simple string) Input selection corresponding to "~50 intrabars per chart bar".      choice8 : (simple string) Input selection corresponding to "~100 intrabars per chart bar".   Returns: (simple string) A timeframe string to be used with `request.security_lower_tf()`. ltfStats()   Returns statistics about analyzed intrabars and chart bars covered by calls to `request.security_lower_tf()`.   Parameters:      intrabarValues : (float [ ]) The ID of a float array containing values fetched by a call to `request.security_lower_tf()`.   Returns: A 3-element tuple: [ (series int) intrabarsInChartBar, (series int) chartBarsCovered, (series float) avgIntrabars ].
