How To Input CSV List Of Symbol Data Used For ScreenerExample of how to input multiple symbols at once using a CSV list of ticker IDs. The input list is extracted into individual ticker IDs which are then each used within an example screener function that calculates their rate of change. The results for each of the rate of changes are then plotted.
For code brevity this example only demonstrates using up to 4 symbols, but the logic is annotated to show how it can easily be expanded for use with up to 40 ticker IDs.
The CSV list used for input may contain spaces or no spaces after each comma separator, but whichever format (space or no space) is used must be used consistently throughout the list. If the list contains any invalid symbols the script will display a red exclamation mark that when clicked will display those invalid symbols.
If more than 4 ticker IDs are input then only the first 4 are used. If less than 4 ticker IDs are used then the unused screener calls will return `float(na)`. In the published chart the input list is using only 3 ticker IDs so there are only 3 plots shown instead of 4.

Light or Dark Mode Tutorial - Luminance DetectionAs a colorblind trader, I think accessibility is a big deal. This script auto detects the chart background color and optimizes text color based on luminance.
Luminance detection is based on pine script new chart.bg_color feature, allowing lines, tables, etc to be optimized. Thanks to TV team for releasing this in the latest update/blog post today! This makes it simple to optimize scripts based off the knowledge that max luminance = 765 (rgb 255 + 255 + 255), thus we know that lum <= 383 is "dark mode" and lum > 383 is "light mode".
Try changing the chart background color and see how this script changes the table printed on the chart. I hope more script authors will begin to utilize this concept and that even better contrast detection may be built future pine script iterations.

How To Color Prior BarsExample how to color the trigger bar of the condition and n-1 prior bars using only 1 barcolor() function.
Currently when offsets are used in barcolor(), bgcolor(), plot(), plotarrow(), plotchar(), or plotshape(), the offset only works with a simple (static) integer. If series (dynamic) integers are used instead, there is not an error, but the series values are ignored. Because of this limitation of offset being constrained to using only fixed offsets, the normal way to paint 3 Black Crows would be to use 3 barcolor() functions. Since there are a known number of bars to be painted in that scenario, this can be easily accomplished.
If a condition encompassed a variable length of n bars, then the number of barcolor() functions needed to use would be unknown. How to color the trigger bar of the condition and n-1 prior bars using only 1 barcolor() function? Dual examples below solves issue but requires n "future" bars, because of this it will not paint the most recent condition in realtime and may not be applicable for use in certain realtime situations. It paints similar in behavior to how a pivot does. Special thanks to LucF and RicardoSantos for illumination!

Scripting Tutorial 8 - Triple Many Moving Averages RibbonsThis script is for a triple moving average indicator where the user can select from different types of moving averages, price sources, lookback periods and resolutions.
Features:
- 3 Moving Averages with variable MA types, periods, price sources, resolutions and the ability to disable each individually
- Crossovers are plotted on the chart with detailed information regarding the crossover (Ex: 50 SMA crossed over 200 SMA )
- Forecasting available for all three MAs. MA values are forecasted 5 values out and plotted as if a continuation to the MA.
- Forecast bias also applies to all forecasting. Bias means we can forecast based on an anticipated bullish, bearish or neutral direction in the market.
- To understand bias, please read the source code, or if you can't read the code just send me a message on here or Twitter. Twitter should be linked to my profile.
- Ribbons added and on by default. Optional setting to disable the ribbons. 5 ribbons between MA1 and MA2 and another 5 between MA2 and MA3.
- Ribbons are alpha-color coded based on their relation to their default MAs.
- Ribbons are only visible between MAs if the MAs being compared share the same Type, Resolution, and Source because there is no way to consolidate those three in a simple manner.
- Ribbon values are calculated based on calculated MA Periods between the MAs.

How To Set Trade Dates
Example how to backtest specific date(s) which can be useful for testing seasonality strategy ideas such as "Sell in May", etc.
If using Daily period with wild card dates it will not trade on 1st day of month. If market is closed will trade on next open day.
Works only with Daily or lower timeframes. When using on Daily timeframe set dates 1 day earlier to execute on desired dates.
Entering 0 in any of the date fields acts a wild card. Example -> Entry Year: 0 is "Every Year", Exit Month: 0 is "Every Month", etc.

How To Use Dynamic ZonesExample of how to apply and use Dynamic Zones with an indicator by injecting it's source into my adaptation of the original idea by Leo Zamansky, Ph.D., and David Stendahl.
• Load your desired oscillating indicator on your chart (CCI, RSI, etc).
• Load my "How To Use Dynamic Zones" indicator on your chart.
• In the "How To Use Dynamic Zones" indicator settings choose your desired oscillating indicator as the Oscillator Source.
You will now have dynamic overbought and oversold levels. I have also included alerts which may be used to indicate when these conditions occur.
If desired you may repeat the above process by loading additional indicators along with additional copies of my indicator to use with each oscillator.
Oscillator Source: CLOSE uses your chosen indicator as a source or you may use price as a source
Sample Length: 70 uses number of previous values for evaluating
Hi is Above X% of Sample: 88 sets overbought zone
Lo is Below X% of Sample: 88 sets oversold zone
The simplest explanation of what these default settings are doing is that they take 70 previous values of your chosen indicator, then create an overbought level that is above 88% of those previous values and an oversold level that is below 88% of those previous values. As new bars form the levels are dynamically reevaluated and updated.

"This investing style follows a very simple form of logic: Enter the market only when an oscillator has moved far above or below traditional trading levels. However, these oscillator driven systems lack the ability to evolve with the market because they use fixed buy and sell zones. Traders typically use one set of buy and sell zones for a bull market and substantially different zones for a bear market. And therein lies the problem.
Once traders begin introducing their market opinions into trading equations, by changing the zones, they negate the system’s mechanical nature. The objective is to have a system automatically define its own buy and sell zones and thereby profitably trade in any market — bull or bear. Dynamic zones offer a solution to the problem of fixed buy and sell zones for any oscillator-driven system."

How To Auto Set Date RangeExample how to automatically set the date range window to be backtested from X days or weeks ago to present. Additional options are also included to manually set the date range or to show entire range available.
Normally when you change chart period it changes the number of days being backtested, which means as you increase the chart period (for example from 5min to 15min), you also increase the number of days traded. So you can not compare apples to apples for which period would yield best performance for your strategy.
By incorporating this code with your own strategy's logic (replacing buy and sell), it will allow you to compare results of different period backtests over the same duration of time.
Date Range: ALL uses entire history.
Date Range: DAYS uses number you set in # Days or Weeks
Date Range: WEEKS uses number you set in # Days or Weeks
Date Range: MANUAL uses manual dates you set in From and To fields
