I developped a MQL4 indicator and have to make it available and downloadable on the website only for 10 days, the time for the user
to try and test it and then decide to get it or not.
My problem is how to make this indicator available only 10 days when the user downloads it.
Any help or any suggestion will be very helpfull.

I have released the first version of my app a couple of days ago & it was available on app store search. I have rolled an update with some bug fixes a day later & the updated version got the status "ready to sale" and was available in app store updates within 6 hours.
But the strange thing i have observed is that, the app was only available from the standard link and was not appearing on app store search.
People were able to download the app using the link but it wasn't showing up on search (even after using the exact name). Any help would be highly valued and appreciated !
PS : when i rolled an update, i changed the keywords and category of the app to more relevant ones.
There could be many reasons for not showing up into the search results. Here are few explained :
May be the ASO changes you have done are not reflected yet so it will not appear in to search. In that case you should wait for 24-48 hours to let things go & settle
Another major & important reason is if App name you are using is very common or already is too much use in other similar apps which already are in the market before your release than also it will put your app far back into the search results that even don't show in limited search results
ASO factor will also effect your app to not appear into the search results. May be you should use more strong keywords which can help your app to compete with other similar apps. You can try & use ASO tools for that.
Last but not the least some times apple has some inner maintenance works which they do silently also affects sometimes to the search results
So from above points the solution is :
Wait for the few hours at least 48 hours to let crawl your ASO keywords & lets get effect in to search result improvements
If it not works since 48 hours you should appeal to apple review team for the same.
Hope it will work to everyone.
I want to retrieve all stocks from few exchanges - by retrieve the stocks that inside those exchanges (by taking from http://www.nasdaq.com/screening/company-list.aspx).
And then I will quote for all stocks from google or Yahoo.
My question is if I will quote all of them for every 5 seconds or 10 seconds - will they block me?
What is the correct way for getting all stocks and they updated data?
Thanks!
David,
tl;dr - yahoo finace is OK (scraping 2,000 stocks) if you insert pauses in your code
I have some clumsy, but working code (my first attempt at scrapping) that pulls some data from Yahoo Finance. While I don't like the code and I will rewrite it for nasdaq.com in following weeks, I can tell you that I'm not getting blocked.
I have a few years old list of stocks for Russel 2000 so there are around 2,000 tickers I'm slowly going through and pulling some data from balance sheet. I'm using Selenium (see my question history, there is only one to see/get working code), code loads Chromium web browser (Linux) clicks on Balance sheet, scrape some data, clicks quarterly link, scraps more data and then closes the browser. For every ticker (stock).
Just to be on a safe side, I put several pauses into my code, for every scrap or navigation on site I added between 5 and 10 seconds. That way I'm slowly scraping data and Yahoo seems to be OK with this :-) It takes about one minute per ticker. I'm running this scrap job (for the first time!) now for over 30 hours lol and I'm currently at ticker that starts with T so I have few more hours to go.
I have read somewhere that some sites can spot this slow scraping also. So as an idea, instead of just hard code pause of say 7 seconds, you could run random number generator between IDK, 7-15 seconds and that way pauses will be more random and less prone to be spotted... Just a though Hope this helps a little bit even if with delay.
Ah, and if this answer does help you, please be so kind to mark it as solved and up vote it. Maybe I can get a point or two for it. My points are so low I can't even vote other posts that I like and that helped me.
this is my first time posting so if I make a mistake correct me please!
I am currently brain-storming an app, and as I have been researching part of it on here, and other places I have come to a bit of a snag. I want the app to be able to access the call timer on a iPhone (as in, it will be able to track how long you are in a call) and then store this information. As of 2011 it seems that this was either not possible, or you had to use something called CoreTelephony. I however could not find any recent material on this, so I was wondering if anything has changed in recent years.
Thanks in advance for any help!
If your trying to count/show how long someone has spent on the phone from the iphone usage data you cannont, If you are trying to show how long someone has been on the phone in your app using your phone/voip or what ever you use then you can use NSTimer
So I'm making an iphone application that needs to scrape a website once everyday.
What I'm going to scrape is a table of upcoming games for that same day for a soccer division. Thats why i need the app to scrape from the same page and same table once everyday to keep the upcoming games updated.
I was referred to import.io but they didn't have something like a schedule re-crawl.
I would love to get some ideas and tips to how i should do this since I'm stuck now.
You might take a look at https://www.kimonolabs.com/
I played around with the service a while back and was impressed with how easy it way to set up. They have a "free" option so long as the APIs you create are not private.
Oh, and I agree with Paul, screen scraping is not something the iOS client should be doing. Too fragile, and when (not if) something breaks, you will need to go through an Apple review process to fix it.
This doesn't seem like something an app should do, your server should do it (so that the scraping is only performed once), and your clients can retrieve it from your server. That also means you could send out push notifications for important fixtures etc. Maybe that's what you meant, anyway.
If it's on the server you can just setup a scheduler (in Java, for example) to run once every x hours (probably a smaller number than 24 assuming you don't know when the website is to be updated). Then your app can just get the latest list of fixtures from your server on startup, pull-to-refresh, etc. Presumably someone will open your app, look at the fixtures, then come out of your app - so it doesn't seem like you need to cover the case where someone is in your app all day, but if you did you could use NSTimer to run every x minutes after the initial on-startup server call.

Is there a clock in iOS that can be used that cannot be changed by the user
I know in many iOS games that have tasks that take time (i.e. "10 hours until animal done breeding"), one can go into "Settings" and change the time to speed up the completion of the task. In the game I'm developing, I don't want users to do this, so I'm trying to implement a system to prevent this type of cheating. I've put a lot of thought into this, but can't come up with a solution. Basically, my question is how do I keep track of time without relying on the system clock (which can easily be manipulated) for the purpose of preventing users from cheating?
transforming my comment into an answer.
Instead of relying on a user or device, rely on an external source for providing unbiased time. A time server, your server, etc. If you don't trust....
Instead of "X hours of real-world time", would "Y minutes of in-app time" work for you? You can pause/continue a timer when your app suspends/resumes.
