Dictionary/Object LibraryThis Library is aimed to mitigate the limitation of Pinescript having only one structured data type which is only arrays. It lacks data types like Dictionaries(in Python) or Object (in JS) that are standard for other languages. Tuples do exist, but it hardly solves any problem. Working only with Arrays could be overwhelming if your codebase is large. I looked for alternatives to arrays but couldn't find any library. So I coded it myself and it's been working good for me. So I wanted to share it with you all. What does it do: ================== If you are familiar with Python or Javascript, this library tries to immimate Object/Dictonary like structure with Key Value Pairs. For Example: object= {name:"John Doe", age: 28 , org: "PineCoders"} And then it also tries to immitate the Array of Objects (I call it Stack) like this: stack= Array({name:"John Doe", age: 28 , org: "PineCoders"}, {name:"Adam Smith", age: 32 , org: "PineCoders"}, {name:"Paragjyoti Deka", age: 25 , org: "PineCoders"}) So there are basically two ideas: Objects and Stacks. But it looks whole different in Pinescript for obvious reasons. Limitation: The major limitation I couldn't overcome was that, for all of the values: both input and return values for properties will be of string type. This is due to the limiation of Pinecsript that there is no way to return a value on a if-else statement dynamically with different data types. And as the input data type must be explicitly defined when exporting the library functions, only string inputs are allowed. Now that doesn't mean you won't be able to use integer, float or boolens, you just need to pass the string value for it using str.tostring() method. And the output for the getter functions will be in strings as well. But I have added some type conversion methods that you could use from this library itself. From String to Float, String To Integer and String to Boolean: these three methods are included in this library. So basically the whole library is based on a manipulatiion of Array of strings under the hood. /////////////// Usage /////////////// Import the library using this statement: import paragjyoti2012/STR_Dict_Lib/4 as DictLib Objects First define an object using this method: for eample: object1= DictLib.init("name=John,age=26,org=") This is similar to object1= {name:"John",age:"26", org:""} in JS or Python Just like we did here in for "org", you can set initital value to "". But remember to pass string values, even for a numerical properties, like here in "age". You can use "age="+str.tostring(age). If you find it tedious, you can always add properties later on using .set() method. So it could also be initiated like this object= DictLib.init("name=John") and later on DictLib.set(object1,"age", str.toString(age)) DictLib.set(object1,"org", "PineCoders") The getter function looks like this age= DictLib.get(object1,"age") name=DictLib.get(object1,"name") The first argument for all methods .get, .set, and .remove is the pointer (name of the object). /////////////////////////// Array Of Objects (Stacks) /////////////////////////// As I mentioned earlier, I call the array of objects as Stack. Here's how to initialize a Stack. stack= DictLib.initStack(object1) The .initStack() method takes an object pointer as argument. It simply converts the array into a string and pushes it into the newly created stack. Rest of all the methods for Stacks, takes the stack pointer as it's first arument. For example: DictLib.pushStack(stack,object2) The second argument here is the object pointer. It adds the object to it's stack. Although it might feel like a two dimentional array, it's actually an one dimentional array with string values. Under the hood, it looks like this //////////////////// Methods //////////////////// For Objects ------------------- init() : Initializes the object. params: (string) e.g returns: The object ( ) example: object1=DictLib.init("name=John,age=26,org=") ................... get() : Returns the value for given property params: (string object_pointer, string property) returns: string example: age= DictLib.get(object1,"age") ....................... set() : Adds a new property or updates an existing property params: (string object_pointer, string property, string value) returns: void example: DictLib.set(object1,"age", str.tostring(29)) ........................ remove() : Removes a property from the object params : (string object_pointer, string property) returns: void example: DictLib.set(object1,"org") ........................ For Array Of Objects (Stacks) ------------------------------- initStack() : Initializes the stack. params: (string object_pointer) e.g returns: The Stack example: stack= DictLib.initStack(object1) ................... pushToStack() : Adds an object at at last index of the stack params: (string stack_pointer, string object_pointer) returns: void example: DictLib.pushToStack(stack,object2) ....................... popFromStack() : Removes the last object from the stack params: (string stack_pointer) returns: void example: DictLib.popFromStack(stack) ....................... insertToStack() : Adds an object at at the given index of the stack params: (string stack_pointer, string object_pointer, int index) returns: void example: DictLib.insertToStack(stack,object3,1) ....................... removeFromStack() : Removes the object from the given index of the stack params: (string stack_pointer, int index) returns: void example: DictLib.removeFromStack(stack,2) ....................... getElement () : Returns the value for given property from an object in the stack (index must be given) params: (string stack_pointer, int index, string property) returns: string example: ageFromObject1= DictLib.getElement(stack,0,"age") ....................... setElement() : Updates an existing property of an object in the stack (index must be given) params: (string stack_pointer, int index, string property, string value) returns: void example: DictLib.setElement(stack,0,"age", str.tostring(32)) ........................ includesElement() : Checks if any object exists in the stack with the given property-value pair params : (string stack_pointer, string property, string value) returns : Boolean example: doesExist= DictLib.includesElement(stack,"org","PineCoders") ........................ searchStack() : Search for a property-value pair in the stack and returns it's index params: (stringp stack_pointer, string property, string value) returns: int (-1 if doesn't exist) example: index= DictLib.searchElement(stack,"org","PineCoders") /////////////////////// Type Conversion Methods /////////////////////// strToFloat() : Converts String value to Float params: (string value) returns: float example: floatVal= DictLib.strToFloat("57.96") ............................. strToInt() : Converts String value to Integer params: (string value) returns: int example: intVal= DictLib.strToFloat("45") ............................. strToBool() : Converts String value to Boolean params: (string value) returns: boolean example: boolVal= DictLib.strToBool("true") ............................. Points to remember ............... 1. Always pass string values as arguments. 2. The return values will be of type string, so convert them before to avoid typecasting conflict. 3. Horses can't vomit. More Informations ==================== Yes, You can store this objects and stacks for persisting through the iterations of a script across successive bars. You just need to set the variable using "var" keyword. Remember this objects and stacks are just arrays, so any methods and properties an array have it pinescript, would be applicable for objects and stacks. It can also be used in security functions without any issues for MTF Analysis. If you have any suggestions or feedback, please comment on the thread, I would surely be happy to help.

ConverterTFLibrary "ConverterTF" I have found a bug Regarding the timeframe display, on the chart I have found that the display is numeric, for example 4Hr timeframe instead of '4H', but it turns out to be '240', which I want it to be displayed in abbreviated form. And in all other timeframes it's the same. So this library was created to solve those problems. It converts a timeframe from a numeric string type to an integer type by selecting a timeframe manually and displaying it on the chart. CTF() str = "240" X.GetTF( str ) Example str = input.timeframe(title='Time frame', defval='240') TimeF = CTF(str) L=label.new(bar_index, high, 'Before>> Timeframe '+str+' After>> Timeframe '+TimeF,style=label.style_label_down,size=size.large) label.delete(L ) Custom timeframes can handle this issue as well. An example from the use. You will find it on the bottom right hand side. Hopefully it will be helpful to the Tradingview community. :)

SignificantFiguresLibrary "SignificantFigures" sigFig(float _float, int _figures) @description Takes a floating-point number - one that can, but doesn't have to, include a decimal point - and converts it to a floating-point number with only a certain number of digits left. For example, say you want to display a variable from your script to the user and it comes out to something like 45.366666666666666666666667 or whatever. That looks awful when you, for example, print it in a label. Now you could round it up to the nearest integer easily using a built-in function, or even to a certain number of decimal places using a reasonably simple custom function. But that's a bit arbitrary. Suppose you don't know what asset the script will be used on, and so you can't predict what the price is, and what the value will turn out to be. It could be 0.00045366666666666666666666667 instead. Now if you round it up to 3 decimal places it comes out as 0.000, which is useless. My function will round that number to 0.0004536 instead, if told to do it to 4 significant digits. I think this is more friendly. @function Converts float with arbitrary number of digits to one with a specified number of significant figures. @param float _float is the floating-point number to manipulate. @param int _figures is the number of significant figures you want. @returns Returns a float with the specified number of significant figures
