Pine Script Boilerplate ExampleI frequently receive questions about my coding style and logic, so I decided to publish a simple indicator that draws the OHLC of a higher timeframe as an example of my coding style. This example will also explain my approach to writing indicators.
This indicator showcases how I use Types and Methods to structure my code and maintain clarity in logic. It demonstrates how I collect input data, organize the flow of the code, and utilize the TradingView method feature.
The example illustrates:
1. The use of input settings within a settings object to keep configurations grouped together.
2. The use of Types to create an object that consolidates relevant data.
3. The collection of objects to create, update, and render elements on the chart.

Dark & Light Theme [TradingFinder] Switching Colors Library🔵 Introduction
One of the challenges of script users is matching the colors used in indicators or strategies. By default, colors are chosen to display based on either the dark theme or the light theme.
In scripts with a large number of colors used, changing all colors to better display in dark mode or light mode can be a difficult and tedious process.
This library provides developers with the ability to adjust the colors used in their scripts based on the theme of the display.
🔵 Logic
To categorize the color spectrum, the range from 0 to 255 of all three main colors red, green and blue was divided into smaller ranges.
Blue color, which is more effective in darkening or lightening colors, is divided into 8 categories, red color into 5 categories, and green color into 3 categories, because it has little effect on darkening or brightening colors.
The combination of these categories creates 120 different modes for the color range, which leads to a more accurate identification of the color and its brightness, and helps to decide how to change it.
Except for these 120 modes, there are 2 other modes that are related to colors almost white or black, which makes a total of 122 modes.
🔵 How to Use
First, you can add the library to your code as shown in the example below.
import TFlab/Dark_Light_Theme_TradingFinder_Switching_Colors_Library/1 as SC
🟣 Parameters
SwitchingColorMode(Color, Mode) =>
Parameters:
Color (color)
Mode (string)
Color : In this parameter, enter the color you want to adjust based on light mode and dark mode.
Mode : Three modes "Off", "Light" and "Dark" are included in this parameter. "Light" mode is for color adjustment for use in "Light Mode".
"Dark" mode is for color adjustment for use in "Dark Mode" and "Off" mode turns off the color adjustment function and the input color to the function is the same as the output color.
🔵 Function Outputs
OriginalColor = input.color(color.red)
= SC.SwitchingColorMode(OriginalColor, Mode)
FUNCTION: Limited Historical Data WorkaroundFUNCTION: Limited Historical Data Workaround
If you are working with bitcoin weekly charts, or any other ticker with a low amount of price history this function may help you out. For example you want to apply indicators to some shitcoin that just launched? This can help you.
It can be frustrating to use certain built-ins since they will only give an output once the full lookback length is available. This function allows you to avoid that situation and start plotting things with almost no history whatsoever!
In this example code we do it by utilizing a replacement for the built in pine SMA function. This function allows us to pass a series instead of just a simple int to the length variable of the SMA. This can be achieved with all the pine built ins and I believe @pinecoders has a publication already detailing many of them with full coded examples.
Then we replace the length of the SMA with the custom history function. It checks to see if the current bar index is less than the length of the function. Then if it is, it changes the length to the bar index allowing us to get plots and series earlier than otherwise possible.
RKs Notepad++ Pine Script V5█ OVERVIEW
After reading all the new names and renames that Pine Script V5 brought to us, I knew that my old Notepad++ User Defined Language (UDL) would need a big update, so I decided to do a complete remake using the same Dark color scheme theme of the Pine Editor.
Then, I create a Notepad++ Theme and the Auto-Completion file with the Parameter hints for every built-in function to make everything look nicer
█ IMPORTANT
This is not an indicator!!
These are 3 XML files to copy and paste inside the Notepad++ folder.
You can use any Notepad Software to create the XML files.
The main Notepad++ folder is normally on %AppData%\Notepad++\
To avoid mistakes, always make a Backup of your files before anything.
█ INSTALLATION
Just follow these steps:
1. open a New Document File;
2. Copy everything between ↓↓↓ and ↑↑↑ symbols to this new document;
3. Remove the "//" of every single line;
4. Save each document with the correct name in the right folder;
5. Restart the Notepad++
█ NOTES:
If you have some problem installing, ask me, and I will try to help you.
But, in any case, here is the link to these files on my GitHub:
Christmas Tree Theme With Open Code To See Pine ScriptI had been trying to code a predictive algorithm working with sine waves, but I got distracted and made some snow and Christmas trees lol. I'm uploading this with the source code because I'm sure someone will be able to learn from it to create something useful.
Please follow me for some actual useful pine scripts and merry Christmas! :)
Heffae Resolution Commander (RAW)This is a script to call resolutions with some math on top of your base resolution.
Using the modulo operator to quantize integer values, it works by converting the modified resolution integer to a 4 digit string value.
Use the function within your own scripts to call funny resolutions otherwise difficult to calculate.
You cannot add series expressions to the resolution value since pine does not allow "series" as a resolution for a security call
However, you could easily stack a crapload of these together and use an expression to switch the referenced security function for your purposes.
This is the raw timeframe output as integer, not string.
To go back to string outputs (for use in security calls etc) unslash line 52 //resvalue
For those interested in the verbose version of the timeframe mod function, showing all the steps, here is a pastebin:

Cheers! Drop a line / comment if you enjoy or have any questions on how to integrate this into your script@!
The Modulo operator is so much fun!
Heffae Resolution CommanderThis is a script to call resolutions with some math on top of your base resolution.
THIS IS NOT AN INDICATOR TO USE ON A CHART!!! The resolution call function is really useful for your own scripting ideas!
Using the modulo operator to quantize integer values, it works by converting the modified resolution integer to a 4 digit string value.
The function within this script is what is valuable, use it within your own scripts to call funny resolutions otherwise difficult to calculate.
You cannot add series expressions to the resolution value since pine does not allow "series " as a resolution for a security call
However, you could easily stack a crapload of these together and use
an expression to switch the referenced security function for your purposes.
The SMA and plot overlay are just there to show a visual example of how the function works.
You can view the raw timeframe output integer by getting rid of tostring(x) and // out the security calls,
plotting the raw function outputs.

EMAcrossover_RSI Buy/sell signal-TRXBTC_15min by rajista EMAcrossover_RSI Buy/sell signal Strategy
To be used in combination with Alerts script, both can be added to your tradingview charts (Chart time-frame should be set to 15min) like you add any other simple indicator.
Add this script to your favorites and once you have been granted access, you will be notified in your Tradingview notifications section, then you can go ahead and add these two scripts into your charts from your favorite section of Indicator menu in Tradingview.
Benefits of this strategy:
1> Fully automated buy/sell signals 24x7
2>Your trades will always be based on a certain entry and exit plan.
3>No emotions involved with these trading calls, so no chance of FOMO buying/Panic Sell
4>You can fully customize the settings with a simple click(customization details given below)
5>Its completely free of cost!!!
There are two parts of this automated trading call system:
1>Strategy script- Gives the buy/sell signals based on the settings provided.
2>Alert script- Gives Alert notifications in tradingview when a buy/sell call is made.
Principle of working is very simple to understand:
Stragey script makes:
Buy call - When the 9EMA crosses above the 21EMA or RSI level-20 is reached in 15min-Chart.
Sell call -When 9EMA crosses below the 21EMA or RSI level-70 is reached in 15min-Chart.
Above values of EMA's and RSI are default values , which can be changed easily in settings panel of Strategy script.
Alert Script allows you to add Alerts when these buy/sell calls are made.
To create a Buy call alert:
1> Click on the create alert icon in your chart (top-centre)
2>Click on Condition -drop down button and select EMAcross_rsi_Alerts
3>Below that bar you will see another bar titled "Buy"-click on its drop down menu and select "Crossing Down"
4>Below that bar right next to Value change 0 to 0.9.
5>Set expiration date for your alerts as per your wish
6>Ensure "Show Popup" and "Play sound" is checked
7>You can check option of sending the alert to your email also.
Finally click on create.
To create Sell Alert:
Repeat same process, except that, after step 2- Do this- change the "long" option to "short" by clicking on the drop down menu right next to the first bar.
Click on create, Finally both of your automated buy/sell call alerts will be configured.
I know its been 2-3 days since i tweeted about this strategy and now i am making it available, you can understand i had to put in a lot of working hours, towards creating the source code for the strategy script and then for alerts script and even more so towards finding the perfect default settings which can be used straight away by anyone, even if you are new in crypto trading, apart from the time which i dedicate to analyse charts and pass on the knowledge/info to you all.
My next post will be even more helpful to you people as i am currently testing "fully automated trading" yea you heard that right!! - This system will trade 24x7 for you guys/girls no matter wherever you are either you are sleeping or watching a movie, your trades would still be getting executed with a proper entery-exit plan on a crypto exchange.
Pine Script Tutorial #2In this second tutorial we build upon the previous tutorial. We add color shading for each different day and highlight Wednesday.
The idea here is to manually count if on Wednesdays close is bigger then open.
Hope it helps.
Feel free to comment.
