Function

Product function for ArraysHello, This code may be useful for Pine script coders only. Arrays were welcomed in Pine script, as they are a foundation for coding properly many useful things, like studies and strategies here in TradingView :) TradingView recently released new functions for arrays, like array.median and more, but the "PRODUCT" function was still missing, so I created it. I've no doubt that array.product() will soon be proposed by the platform, but for the time being, one can use mine. It does the same thing as the PRODUCT() function in Excel : it multiplies all the source values included in the specified lookback, and returns the product. This function can accept Series or Arrays as source input.

Unicode Font Function V2 - JDThis script is a continuation from Duyck's Unicode font function A different approach made on this function to able change font type on a single string Now you can call it as a function to change the font type on every string that you need, either it is for a Label or regular Text Shoutout to @Duyck for his amazing works on this function. Thank you to PineScript Community as well Let me know if you guys have any suggestion or idea. Greets, dddfault

Function Square WaveThis is a script to draw a square wave on the chart, with an indicator for current price. Markets undergoing Dow Jones or Wyckoff Accumulation/Distribution cycles tend to move in such waves, and if the period of the cycles are detected, a signal for accumulation/distribution phases can be created as an early warning. Useful inputs: - Average True Range as the wave height. - Assumed Wave period as the wave duration. I divided the current price wave by 2 to make the indicator more visually friendly. GLHF - DPT

Function Sawtooth WaveThis is an indicator to draw a sawtooth wave on the chart. It can be a useful perspective, as decaying markets tend to oscillate in reverse sawtooth waves, and bullish markets can oscillate in conventional sawtooth waves. With the right inputs, it can be an early warning signal for potential movements. Something I've noted is that large waves cause a ripple effect and sets the frequency for the market until a change occurs. Sawtooth waves may help in capturing ripple waves. Useful inputs are: - Average True Range as wave height (amplitude) - Periodicity of market as wave duration (frequency) (Inputs will change the wave from conventional to reverse) I hope that it is helpful.

Pinescript - Common String Functions Library by RRBCommon String Functions Library by RagingRocketBull 2021 Version 1.0 Pinescript now has strong support for arrays with many powerful functions, but still lacks built-in string functions. Luckily you can easily process and manipulate strings using arrays. This script provides a library of common string functions for everyday use, such as: indexOf, substr, replace, ascii_code, str_to_int etc. There are 100+ unique functions (130 including all implementations) It should serve as building blocks to speed up the development of your custom scripts. You should also be able to learn how Pinescript arrays works and how you can process strings. Similar libraries for Array and Statistical Functions are in the works. You can find the full list of functions below. Features: - 100+ unique string functions (130 including all implementations) in categories: lookup, testing, conversion, modification, extraction, type conversion, date and time, console output - Live Output for all/selected functions based on User Input. Test any function before using in script. - Live Unit Test Output for several functions based on pre-defined inputs. - Output filters: show unique functions/all implementations, grouping - Console customization options: set custom text size, color, page length - Support for Pages - auto splits output into pages with fixed length, use pages in your scripts - Several easy to use console output functions to speed up debugging/output. WARNING: - Compilation Time: 1 min Notes: - uses Pinescript v3 Compatibility Framework - this script is packed to the max and sets a new record in testing of Pinescript's limits: 500 local scopes, 4000+ lines, 180kb+ source size. It's not possible to add more ifs/fors/functions without reducing functionality - to fit the max limit of local scopes = 500 all ifs were replaced with ?: where possible, the number of function calls was reduced, some calls replaced with inline function code - ifs are faster (especially when lots of them are used in a for cycle), more readable, but ifs/fors/functions increase local scopes (+1) and compiled file size, have max nesting limit = 10. - ?: are slower (especially in for cycles), hard to read when nested, don't affect local scopes, reduce compiled file size, can't contain plots, for statements (break/continue) and sets of statements - for most array functions to work (except push), an array must be defined with at least 1 pre-existing dummy element 0. - if you see "String too long" error - enable Show Pages, reduce Max Chars Per Page < Max String Length limit = 4096. - if you see "Loop too long" error - hide/unhide or reattach the script - some functions have several implementations that can be faster/slower, use internal code/ext functions - 1 is manual string processing using for cycles (array.get) and ext functions - provided in case you want to implement your own logic, may sometimes be slower - 2 is a 2nd alternate implementation mostly done using built-in functions (array.indexof, array.slice, array.insert, array.remove, str.replace_all), attempts to minimize local scopes and dependency on ext functions, should generally be faster - 3 is a 3rd alternate (array.includes, array.fill) or a more advanced implementation (datetime3_str) with lots of params, giving you the most control over output - most functions have dependencies, such as const names, global arrays, inputs, other functions. P.S. Strings of Time may be closed unto themselves or have loose ends; they can vibrate, stretch, join or split. Function Groups: 1.

Examples of Rolling Average Using Automated AnchoringIn this study, I present a method to expose NaN values to development environment. This exposure allows NaN values to be used by methods in scripts. I also show how to use values, even NaN values, as anchors from which statistics can be computed from. I demonstrate how to do this with constants and variables in methods for computing the cumulative/rolling average of a series. I also show how to calculate the cumulative/rolling average from the start of a ticker series using the aforementioned methods. Each method has a description on how some of their parts work as well as their constraints. Method #1 - Can only be used for computing the rolling average on the ticker series. Method #2 - The simple moving average from the Pine Script reference. - Can be used to calculate the rolling average of the ticker series and number values of a series. - This method seems to cause an error when there are many bars in the series. Method #3 - The most versatile method due to the use of computing the rolling average using an array. - Timeout will occur when computing the rolling average of an entire ticker series which is long. - Timeout has not occurred when computing a rolling average of a series from NaN or non-NaN anchor points even when the series is long. This is an attempt to get around the constraints of the built-in sma(source, length) function in which length cannot be dynamically adjusted. Other Pine Script functions have that constraint which we can get around by defining our own functions.

Remember Rules Label - incl. Text Function with different colorsHi BIG PLAYERS Each of us makes mistakes and exceptions confirm the rule. However, if you disregard the rules of trading, you lose your money - without any ifs and buts! I have therefore created a reminder label for myself, which trading approaches I always want to stick to. These rules serve me as a guideline when I should trade. Through the permanent reminder I set myself the goal of not trading too early and impatiently. The biggest problem of all traders is overtrading: the constant swaying back and forth between greed and fear. This must always be kept in mind. Because trading is in principle very simple: stick to your own rules. Keep a logbook and for my sake, record every trade as a screenshot in a PowerPoint presentation. Then you can see your mistakes in the past trades and recognize your background, why loss trades have arisen - you can also determine profit trades: As a rule, profits arise when you strictly adhere to your trading rules. If you compare a company with a trader, then it is generally a similar procedure. company view a company plans its annual development with budget and forecast. a company compares monthly between actual values and plan values and draws conclusions from the differences. trader view a trader should handle and plan his trade with all rules. a trader should compare the result after the trade with the planned trade and discuss conclusions from possible differences. I hope I could help other traders with this. Kind regards NXT2017

Mod and Round To Tick FunctionI have not found this function anywhere on Tradingview but it can be very useful in setting orders in a strategy and non-integer boundaries for certain indicator designs. Its a bit underwhelming, but in other languages you can call a mod() function and the output will be the remainder of the integer. If you want to set an order at a specific tick value, particularly in futures, you can't set it at a specific tick when using calculated values like ATR or Standard Deviation without a function like this. It can also be used to clean up certain band/envelope style indicators if you want to have a straight line, but don't want to simply round to an integer. Credit for the round to tick aspect goes to the eternal fountain of resources, the Backtesting & Trading Engine script from @pinecoders This is just another tool to throw in the box for when you might need it.
