The provided Pine Script is a TradingView script for creating a technical analysis indicator called "Humble LinReg Candles." This script includes features such as linear regression for open, high, low, and close prices, signal smoothing with simple or exponential moving averages, and a trailing stop based on Average True Range (ATR). Additionally, the script contains a screener section to display signals for a list of specified symbols.

Here is a breakdown of the script:

Indicator Settings:

It defines various input parameters such as signal smoothing length, linear regression settings, and options for using simple moving averages.
Linear regression is applied to open, high, low, and close prices based on user-defined settings.
ATR Trailing Stop:

It calculates the Average True Range (ATR) and uses it to determine a trailing stop for buy and sell signals.
Signals are generated based on whether the close price is above or below the ATR trailing stop.
Plotting:

The script plots the calculated signal on the chart using the plot function.
Buy and Sell Conditions:

Buy and sell conditions are defined based on the relationship between the close price and the ATR trailing stop.
Plot shapes and bar colors are used to visually represent buy and sell signals on the chart.
Alerts:

Alerts are triggered when buy or sell conditions are met.
Screener Section:

The script defines a screener section to display a watchlist of symbols with long and short signals.
The watchlist includes a set of predefined symbols with corresponding long and short signals.
Table Theme Settings:

The script allows customization of the table theme, including background color, frame color, and text color.
The size and location of the table on the chart can also be customized.
Screener Function:

A function getSignal is defined to determine long and short signals for each symbol in the watchlist.
The getSym function is used to extract the symbol name from the symbol string.
Dashboard Creation:

The script creates a table (dashboard) to display long and short signals for the symbols in the watchlist.
The table includes headers for "Long Signal" and "Short Signal" and lists the symbols with corresponding signals.
Overall, the script combines technical analysis indicators and a screener to help traders identify potential buy and sell signals for a set of specified symbols.
