Evaluating condition in AFL

[SHANTVCI]

I want to execute exploration to find out the stocks which do not cross particular price ( X) from the trading start day to a predetermined time ( T ) of the trading day and the stock price crosses X after T. Is it possible to code this AFL?

Yes.

Sorry for being a "smart alec" but as a new member, you can probably learn more by using the SEARCH function (Magnifying Glass in top right area of your screen).

Like all good things... you get more out of it the more you put in to it. Read, Search, Learn.

Thanks for your input. Please guide if you know the code for this scan.

How to use this site

Search the forum It is good idea to search the forum before asking same questions over and over. To search the forum just use magnifying glass icon in the upper right corner [image] Also it is good idea to use Google and add +site:amibroker.com to your search term to limit the output to content of amibroker.com web site. Doing so will include results from Knowledge Base and Users’ Guide Enter the AFL code properly It is of utmost importance as improperly formatted code results in syntax error…

How do I debug my formula?

Continuing the discussion from How do I learn AFL?: Many new users with zero programming experience struggle when their formula works incorrectly. Here are few hints that everyone should use to make finding errors easier. First of all: you have to get insight into what the formula is actually doing, not what you think it does. Typically new user has no idea what is happening inside. Pretty often you make an assumption that things work one way but in fact they work differently. Do not assume t…

Scan, Exploration Back Test

Hi Thank you for your answer. I searched here and could not find comparison like you gave. I am testing a piece of AFL code in all the three Scan, Explore and Back Test, but they are producing difference outputs of signals. So I wanted to understand is there any different approach in their working, that is why I posted the original question. still try to figure out the reason for that. Thank you very much.

HHV and LLV of Specific Time range in Intraday

@Gloriafilamino this article might help, http://www.amibroker.com/kb/2015/02/02/high-low-of-certain-hours-of-the-day/ And an example tn = TimeNum(); StartTime = 093000; EndTime = 101500; // these conditions are true when TimeNum of the bar equals startime/endtime StartBar = tn == StartTime; EndBar = tn == Endtime; // on the end bar we read the value of highest high since the start bar myH = ValueWhen( EndBar, HighestSince( StartBar, High ) ); Filter=1; AddColumn(High, "High"); …

Again, as a new member, you need to do a bit of homework. The helpers on this site prefer to see that you have put some work in and tried something. We are not here to write code for you, but we like to help people with challenges, or point them in a likely direction.

When you do your homework, and start to break your problem down and make code for it, then you can tell us what specific problem you are having and you will usually find several people able to contribute ideas. Just asking for a solution does not show that you have done any work.

By reading the above links, you should get several ideas:
Post your code properly - with code blocks
Break down the problem into small parts
READ the Manual
Show your work and specify what you are having an issue with

Thanks a lot. This will help me in writting the code for my strategy.
