For this, I added the expression of the rsi bult-in function in the security call, to send as a return to the plot function.
Ps. I purposely inverted the...

In 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...

_Y: Array containing y data points.¹
Note:
¹: _X and _Y size must match.
Outputs:
_predictions: Array with adjusted _Y values at _X.

20 step red/green gradient function
The color gradient function allow colorize any source in 5% steps.
Define the source, minimum and maximum value (constant or , for example, bb (or any other channel)).
EXPERIMENTAL:
Using keltner channels with automatic multiplier finding, offsets and show_last cutoffs to generate a forecast area.
video showing why its named keltner worms :p..

Function - Number of digits before and after the decimal point
Detect the number of digits in integers and floats, before the decimal and after it.
It also works for negative numbers.
There are some rounding issues, but the currently maximum supported number can have safely up to 3 digits after the decimal point.
Hi 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...

_Y: Array containing y data points.¹
_number_of_clusters: number of clusters.
Note:
¹: _X and _Y size must match.
Outputs:
_centers_x: Array containing x data points.
_centers_y: Array...
Nth-Occurrence Custom barssince() Function by Cryptorhythms
Description
The vanilla barssince() function in pine only finds the number of bars since the most recent occurrence of the condition. This version allows you to specify an Nth occurrence back to check the bars since! Its also a nice little one liner.
I really hope you enjoy it and if you're...
Oftentimes a single look at the candlestick configuration happens to be enough to understand what is going on. The chandlestick function is an experiment in smart labelling that produces candles for various time frames, not only for the fixed 1m, 3m , 5m, 15m, etc. ones, and helps in decision-making when eye-balling the chart. This function generates up to 12 last...
I 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,...
