indicator | Some indicators like MACD,KDJ,BOLL etc with Golang

when I run android application in real device I am getting following gradle errors

I'm new to Julia and I'm trying to add a technical indicator (let it be a simple moving average) to my candlestick chart. How should I do that?

This question is in the continuity of this one: Is it possible to stop executing of R code inside shiny (without stopping the shiny process)?.

The plot that I display in my app takes some time to produce, and I want the users to be able to stop its creation (for instance if they made a mistake in the options). I found this blog post about using callr in Shiny. The workflow is the following:

• create an empty list of jobs/plots
• clicking on "start" creates a background process to create the plot
  • if the user doesn't do anything, the plot is computed in the background. I use invalidateLater() every second to check if the background process is finished. If it is, then I display the plot.
  • if the user clicks on "stop" before the end of the process, the process is killed, removed from the list, and the previous plot is displayed (if there was no plot produced before, nothing is displayed)

First, I'm not sure how this would scale when several people use the app at the same time. Since every background process is independent, I don't think one user would be blocking the others, but I may be wrong.

Second, I'd like to show a waiting indicator on the plot. So far, I used the package waiter to do that, but the problem here is that renderPlot() is being invalidated every second to check if the background process is finished. Therefore, waiter appears and disappears repeatedly as the output is being invalidated.

Below is an example app that mimics the behavior I'd like to have:

Apparently, discord bots can have mobile status as opposed to the desktop (online) status that one gets by default.

After a bit of digging I found out that such a status is achieved by modifying the IDENTIFY packet in discord.gateway.DiscordWebSocket.identify modifying the value of $browser to Discord Android or Discord iOS should theoretically get us the mobile status.

After modifying code snippets I found online which does this, I end up with this :

I would like to use a combination of mutate, across, and case_when to set some cases to NA (missing) across multiple variables.

Say I have an indicator variable "vs" flagging cases that should be NA for variables "carb" and "gear". I would like to use something like this to set those cases to missing on both those variables at once:

I recently submitted a package to CRAN that passed all the automatic checks, but failed passing the manual ones. One of the errors were the following:

Please do not set a seed to a specific number within a function.

Please do not modifiy the .GlobalEnv. This is not allowed by the CRAN policies.

I believe the lines of code that these comments are referring to are the following

I need to implement a sticky tab bar. The same tab bar can be of variable length, as different merchants can have different number of categories.

My current code for merchant page is as:

As defined here the Hindenburg omen indicator is:

The daily number of new 52-week highs and 52-week lows in a stock market index are greater than a threshold amount (typically 2.2%).

To me it means, we roll daily and look back 52 weeks or 252 business/trading days, then count the number of highs (or lows) and finally compute the return of that or pct_change, which is the ratio of new highs (or lows) they want to monitor e.g., being above 2.2%

In my Android app, I am have been able to auto-scroll view pager after a certain duration. I could not find a pager indicator that would show the time remaining before the scroll happens.

I have attached screenshot of a website below to give an idea of what I am trying to achieve.

Would help if you could share a library or code you have used for the tab indicator.
