CCI/MFI/VZO/RSI - HEATMAP

2021年5月22日

Heatmap I made/reverse engineered.

Currently tracks the 4 following oscillators:
- CCI (Channel Commodity Index)
- MFI (Money Flow Index)
- VZO (Volume Zone Oscillator)
- RSI (Relative Strength Index)

Any feedback or suggestions highly appreciated.

版本注释

Clarified user input.

- Changed levels (editable = false) -> These where transparent 100% anyways so made the input screen unorganized.
- Changed plot (editable = false) -> These where transparent 100% anyways so made the input screen unorganized.

Only the inputs that have visual difference are now being shown i.e the fill colors

VERSION 1.4

On request, I added buy/long and sell/short signals dependig on certain conditions. The indicator will display those above or below the heatmap. Unfortunately, I had to add some 'whitespace' above and below the heatmap for the signals to become visible, otherwise the signals would blend in with the heatmap.

I want to keep this as a standalone indicator. If you want me to turn this into a strategy, let me know and i'll make a new script for this.

VERSION 1.5 (because why not)

CORE CHANGES:
Added color gradients instead of using if/else stacks for choosing color. Thankfully, a gradient framework was already in circulation by PineCoders
You can find the framework here:

- Removed the two 'whitespace' horizontal lines again so it looks more clean in my opinion.
- Changed the plotchart symbols to the color white so it is visible even if the oscillator has the maximum color gradient assigned.
- Added more comments to the code for better reusability

VERSION 1.6

- Added input for customizing the colors that are used for the gradient (Default values: #0097A7, #9C27B0 - Bullish, Bearish)
- Removed the Oscillator inputs and turned them into constants (Default values: 14, 28, 14, 28 - RSI, VZO, MFI, CCI )
- Removed some unnecessary code: unused color constants and colors needed for previous versions
- Reformatted the code for easier source reading and reusability

版本注释

• Version Information: The version number and author information have been removed from the code.
  
• Simplified Input Colors: The user input colors are now set using the simple #RRGGBB format instead of input.color function. Additionally, the input names have been adjusted for clarity.
  
• Renamed Gradient Function: The function f_c_gradientRelativePro has been removed, and the existing f_c_gradientRelative function now handles both cases of gradient color calculation.
  
• Removed Redundant Constants: The color constants (C_AQUA, C_BLACK, etc.) have been removed as they were not used in the updated code.
  
• Updated Horizontal Lines: The horizontal lines (h0, h1, h2, h3, h4) are now created using hline with the input values (oversoldThreshold, overboughtThreshold, etc.) directly, avoiding any redundant intermediate variables.
  
• Updated Signal Conditions: The conditions for generating Long and Short signals have been modified for better performance and accuracy.
  
• Signal Marker Colors: The color for the Long and Short signal markers (▲ and ▼) is now set to alertColor to be consistent with the color used in other parts of the indicator.
  
• Removed Unused Commented Code: Some commented-out plotting statements have been removed from the code for better clarity and to reduce unnecessary lines.
  
• Removed Gradient "center" variable: The _center variable used in the gradient function has been removed, and the calculation is directly applied within the color.from_gradient function.
  
• Updated Gradient Colors: The input color names used in the gradient function are updated to match the new input names, and the gradient calculation is simplified using ternary operators.

版本注释

• Changed the default values for the oversoldThreshold and overboughtThreshold inputs from 25 and 75 to 26 and 74, respectively.
  
• Updated the horizontal lines for h1 and h2 to be at levels 25 and 50, respectively.
  
• Renamed the variable test to combined to reflect its actual purpose.
  
• Changed the title of the plot from "Combined" to "Combined Heatmap" to provide a more descriptive name.
  
• Removed the editable=false property from the horizontal lines h1, h2, h3, and h4 since editable properties are not applicable for script plots.
  
• Adjusted the conditions for the enterLong and enterShort signals based on the new threshold values (26 and 74).

I have rolled out an updated version of the CCI/MFI/VZO/RSI Heatmap indicator. Here's what's new and what you can expect:

Pine Script Version
The indicator is now using Pine Script version 5, which allows us to make use of newer features and functionalities. This makes the indicator more robust and compatible with future updates.

User Inputs
The color input fields have been simplified. You no longer have to specify the type of input; the script automatically detects it based on the default value. This makes the setup process a tad quicker.

Technical Indicators
The calculation logic for RSI, VZO, MFI, and CCI remains the same. So, you can expect the same level of accuracy and performance as the previous version.

Visual Enhancements
We've added transparent horizontal lines for better visual cues. These lines will help you quickly identify the different regions of the plot, enhancing readability.

Code Efficiency
The code has been optimized for better performance, although the core functionalities remain the same.

Signals
The buy and sell signals are generated in the same manner as the previous version, keeping the strategy consistent.

New Color Scheme
The color scheme remains the same; however, the script is now more efficient in generating the gradient colors, which should result in smoother transitions.

Please note that these updates are aimed at improving the efficiency and readability of the indicator. Feel free to reach out if you have any questions or encounter any issues.
