📕 LIBRARY OHLC


🔷 Introduction

This library is a custom library designed to work with real-time bars. It allows to easily calculate OHLC values for any source.
Personally, I use this library to accurately display the highest and lowest values on visual indicators such as my progress bars.



🔷 How to Use

◼ 1. Import the OHLC library into your TradingView script:

import cryptolinx/OHLC/1

- or -

Instead of the library namespace, you can define a custom namespace as alias.

import cryptolinx/OHLC/1 as src

◼ 2. Create a new OHLC source using the `new()` function.

varip mySrc = OHLC.new()  // It is required to use the `varip` keyword to init your `<OHLC.src>`

- or -

If you has set up an alias before.

varip mySrc = src.new()

===

In that case, your `<OHLC.src>` needs to be `na`, define your object like that

varip <OHLC.src> mySrc = na

◼ 3. Call the `hydrateOHLC()` method on your OHLC source to update its values:

Basic

float rsi = ta.rsi(close, 14)
mySrc.hydrateOHLC(rsi)

- or -

Inline

rsi = ta.rsi(close, 14).hydrateOHLC(mySrc)

◼ 4. The data is accessible under their corresponding names.

mySrc.open
mySrc.high
mySrc.low
mySrc.close

🔷 Note: This library only works with real-time bars and will not work with historical bars.

🔷 Release Notes v4

🔷 What's New

1. Renamed hydrateOHLC to hydrate.
   
2. Optimized hydrate() method for improved performance
   
3. Added support for series int input in hydrate()
4. Optimization - varip declaration now handled internally
   
5. Improved documentation and examples
   

🔷 Key Features

- Easy calculation of OHLC values for any source
- Real-time bar support
- Flexible integration with existing scripts

🔷 How to Use

1. Import the updated OHLC library:

import cryptolinx/OHLC/4 as ohlc

2. Create a new OHLC source:

mySource = ohlc.src.new()

3. Update the OHLC values:

rsi = ta.rsi(close, 14).hydrate(mySource)

or

mySource.hydrate(rsi)

4. Access the OHLC data:

mySource.open
mySource.high
mySource.low
mySource.close
mySource.update_no

🔷 Optimization Improvements

• The varip keyword is now automatically applied internally, eliminating the need for manual declaration
  
• This change simplifies usage and ensures optimal performance by default
  

🔷 Note
This library is designed for real-time bars and may not provide accurate results with historical data.
