vix | VMware VIX API binding for Python | REST library

I am beginner to R and was hoping to have ideas for making a loop.

I would like to automate the following for each observation out of 726 observation making a 5 ahead out-of-sample forecast based on a rolling window of 1000 obsv, storing only the t+5 in the "pred" column and then reset the "VIX.Close" column to his original values.

I am struggling to make a graph, using ggplot2. below, you can see the output I get and the relative code:

I'm creating a basic webpage that will have a fixed sidebar and scrollable content area. Unfortunately, every single solution I've found

1. flat-out isn't working (meaning the sidebar sticks to the page and disappears as one scrolls down), or
2. cuts off the image container that holds these two images in place at the top of the main content area, plus everything above it.

Here's the codepen for the project: https://codepen.io/__JMar1/pen/jOYroOY

Let's suppose I have a long text that I want to process with an API having a maximum number of allowed characters (N). I would like to split that text into 2 or more texts with shorter than N characters, and based on a separator. I know I could split by separator but I would like to keep the number of output sub-texts the smallest as possible.

For example, suppose my text is:

"Lorem ipsum dolor sit amet, odio salutandi id nam, ferri nostro te duo. Eum ex odio habeo qualisque, ne eos natum graeco. Autem voluptatum ex mea. Nulla putent reformidans cu pro, posse recusabo reprehendunt pro no. An sit ludus oblique. Consulatu cotidieque ex sea, nam no duis prompta expetendis.

Est ne tempor quaestio complectitur, modo error vim et. Option voluptaria efficiantur te eam, ea appareat evertitur qui, te vix pertinax recteque. Mea eu diceret ceteros. Expetenda torquatos assueverit est ex, te reque voluptatibus signiferumque has."

which is 550 characters long. Let's suppose that N is 250. I would expect the text to be split in this way:

• Part 1: "Lorem ipsum dolor sit amet, odio salutandi id nam, ferri nostro te duo. Eum ex odio habeo qualisque, ne eos natum graeco. Autem voluptatum ex mea. Nulla putent reformidans cu pro, posse recusabo reprehendunt pro no. An sit ludus oblique" (237 characters)

• Part 2: "Consulatu cotidieque ex sea, nam no duis prompta expetendis.

Est ne tempor quaestio complectitur, modo error vim et. Option voluptaria efficiantur te eam, ea appareat evertitur qui, te vix pertinax recteque. Mea eu diceret ceteros." (232 characters)

• Part 3: the remaining.

Any idea on how to do this in Python?

Thank you for any help. Francesca

I have a dataframe called df which looks like this:

and I have another dataframe called vix which looks like this:

previously I added the columns 'open ndaq' , 'open jpm' and 'open kya' like this:

Is there anything in GNU Make that allows for dependency on date and/or time?

Currently I have a Makefile that checks whether or not to download the latest financial data. The target is something like stock_symbol.csv, and the important dependency is a a file called last_updated.txt. last_updated.txt changes once a day, and when it does, make will know to refresh my historical data.

The annoying thing is that I have to change this finally manually, or let some other program (e.g. cron) modify it on a schedule. I'm wondering if there's a way to remove the need for external programs here. Does Make have anything that will achieve this?

This is my present Makefile

I have four dataframes vom yfinance:

I'm having trouble redirecting any exception to an error page. When the error occurs, the method is called, but there is no redirection of the page, continuing in the same one that performs the action. The method code looks like this:
