Error Message -- DemoThis script is proof of concept to display an “error message” to provide user feedback when valid, but non-logical variables are input by the end user. In this example, the user enters a lower limit that is greater than the upper limit. The Pinescript user input box allows input types and min/max values, but it does not allow input conditions like (Upper > Lower) for each variable. This script evaluates the user input and determines if the variables are logical. If not, it will print an error box using the new Pinescript table function.
This is a demo only – there are no signals, strategies, or alerts. Hopefully, some pinescripters will find this idea useful and expand on the concept.
User inputs an Upper Limit that is lower than the Lower Limit – error message displayed.
User inputs logical Upper and Lower Limits (Upper Limit is greater than Lower Limit) – normal plots.

Examples of Rolling Average Using Automated AnchoringIn 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 which statistics can be computed from.
I demonstrate how to do this with constants and variables in methods for computing the cumulative/rolling average of a series.
I also show how to calculate the cumulative/rolling average from the start of a ticker series using the aforementioned methods.
Each method has a description on how some of their parts work as well as their constraints.
Method #1 - Can only be used for computing the rolling average on the ticker series.
Method #2 - The simple moving average from the Pine Script reference.
- Can be used to calculate the rolling average of the ticker series and number values of a series.
- This method seems to cause an error when there are many bars in the series.
Method #3 - The most versatile method due to the use of computing the rolling average using an array.
- Timeout will occur when computing the rolling average of an entire ticker series which is long.
- Timeout has not occurred when computing a rolling average of a series from NaN or non-NaN anchor points even when the series is long.
This is an attempt to get around the constraints of the built-in sma(source, length) function in which length cannot be dynamically adjusted.
Other Pine Script functions have that constraint which we can get around by defining our own functions.
