Pine-script optimization - optimization

In AmiBroker there is optimize option. It allows you to fine tune values for indicators or even any other parameters. Is there anything like that in pine script? couldn't find it easily using google.

No. Can't be done automatically yet on TV. Adding the feature is being considered though.

there are private chrome extensions. just a couple months ago there were some public versions but TV has started banning people and finding ways to shut down the extensions ability to properly see and feel the page

Automation scripts: autoitscript vs ptfbpro

I try to use this 2 projects for primitive gui testing automation:
http://www.ptfbpro.com/
http://www.autoitscript.com/
And I can't make my choice.
Can somebody explain me: why(in 2 or 3 lines) he use one of them(or other please specify)?
I use AutoIt...
because it's free, well documented (not only) from inside of the Scite Editor and you can easily compile your script into a small executable or even create a complete GUI and there is a very good community in the forums and around here. And its Basic-Like Syntax is really easy to understand, there are functions and even a foreach-syntax, dynamic arrays and lots of additional functions from other users... There's good integration with other programming languages and from the use of so many WinAPI functions you lack of very little possibilities. It can automate IE usage without even displaying a browser window and send network packages, you can send Keystrokes like a user sitting in front of your screen and there's the AU3Record Tool which allows you to just record a Macro and replay it or save it as a script and then you can easily optimize it and edit it for your needs. Or use the AutoIt Window Info tool to see all the possible handlings for your application, you can interact with any kind of program output/display according to different algorithms you may invent.
Enough facts? ;-)
Go with Autoit3. It 's a lot more reliable, and you have a complete script language. Ptfbpro is only a tool (not free), nothing more. AUtoit3 has a lot of contributors that can help you in your process, Ptfbpro is dead.
If you want a script taht really do what you want, just go for AutoIt. Ptfbpro can't be used as a professional tool.
Autoit3 as well. You really can't beat it for being free and so easy to use.

How to create an online rebol console?

Where can I find the code for creating an online rebol console like the one here ?
http://tryrebol.esperconsultancy.nl/
Update: for the sandbox system on the server, can't Rebol manage it itself with some security wrapper and its security options ?
As for console itself, I don't know Ruby so I don't want to use TryRuby and why would I need it ? Can't I mimic Rebol console itself by "remoting" it somehow ? Why RT or Esper Consultancy can't make an opensource version ? There's no value in keeping it closed source. Rebol needs to prove it's more open than in the past.
In my opinion, you should aim higher with something like the already open-sourced Try Ruby. You'd type in expressions and it would guide you. Their showcase site is at tryruby.org and is fairly slick.
I modified TryRuby to work with Rebol and it wound up looking like this:
But I'm not going to run it on my server because I didn't want to belabor the necessary sandboxing/etc. or protections against someone running an infinite loop. I can give you what I've got so far if you want it.
I started a tutorial script here that no one seemed interested in helping me with, so I wandered off to other tasks:
http://www.rebol.net/wiki/Interactive_tutorial_script
I'm not sure what exactly you want. You mention you want a remote REBOL shell instead of a tutoring setup, but that's what the Try REBOL site is. There are several reasons it's not open source:
It's in heavy development. I'm currently changing the code regularly.
So it's not in a release state. Preparing it for release, documenting and publishing it would take a lot of extra work, as with most projects.
It's written in my CMS that's also in heavy development. Even if the Try REBOL site were open source, it wouldn't run. The CMS is not planned to be open sourced soon.
It's not meant as a generic REBOL remoting tool, but as a one-off demo site. If that site is running, what's the use of more of them?
As others have answered, there are many generic solutions for remoting that you could use. Also, most parts of the Try REBOL site are readily available as open source:
Syllable Server, produced and published by us.
The Cheyenne web server.
The HTML source of the web client can be viewed, including my simple JavaScript command service bus.
Syllable Server is an essential part of the site, as the sandboxing is not done with REBOL facilities (except some extra limits in the R3 backend), but with standard Linux facilities.
A truly air tight (do I mean silica tight?) sandbox is close to impossible with R2.
R3 (still in alpha) is looking a lot more promising. The deep technical discussions in flight right now (see Cure code and AltME/REBOL3 Proposals regarding unwinds and protect and even occasionally mentioning sandboxes should lead to an excellent sandbox capability.
Right now, the big advance R3 has that makes Kaj's tryREBOL possible is R3's secure policy settings which make it possible (with some careful wrapper code) to construct an alpha/demo sandbox.
To answer your precise question("where can I find code...", you could try asking Kaj for his :)
I'm new to StackOverflow. I'm not sure if this is going to end up as a reply to your comment, or as a new answer.
The somewhat common idea that any project can be open sourced and contributed to by others is a naive view. In the case of my Try REBOL site, it makes no sense. It's not just in heavy development; it's written in a CMS that's also in heavy development. Basically noone could contribute to it at this point, because I'm the only one who knows my CMS. Or in any case its newest features, which I develop by developing Try REBOL, and other example sites. So developing Try REBOL means developing the CMS at the same time, and by definition, I'm the only one who can do that.
More generally, my projects are bleeding edge, innovative technology with a strong vision. The vision is mine, and to teach it to others, I have to build it to show how I intended it to work. So there's a catch 22: to enable others to contribute, I have to finish my projects first, because people typically don't understand them until I show them how they work.
There certainly are other projects where mass contribution makes more sense. Still, only the top projects get the contributors. We found that out the hard way. We created Syllable Desktop and Syllable Server with surrounding infrastructure for contributions. These are fairly classic, well understood operating systems that many people could work on in parallel. However, despite years of begging, we get very few contributions.
So, if you feel a burning need to contribute to our projects, please pick one of the many tasks in Syllable to execute. :-)

How can I go about automating the testing of the migration of local web apps from IE6 to IE8?

I have been researching this a wee bit and it seems to boil down to:
'Eyeball Mark 1'
The best tip seems to be the use of SuperPreview from Microsoft's Expression team.
If anyone has automated a way to go about this I would love to hear about it.
Also, I believe that SuperPreview requires a work around for a password protected app to work properly. There is a work around at MSDN Blog, but if anyone has come up with another way, could you share it with me please?
Thanks in advance!
Some products, like Telerik WebUI Test Studio, lets you build your test and play a movie with the results in different browsers (not sure about IE6 and IE8 support)
Others lets you compare bitmaps of screenshots of tests in one browser and the other. The problem is that the minimum 1-bit shift will result in an test error.

XRCed learning resources?

I've seen many people saying XRCed very strong "if you have learned how to use it". Unfortuntately, there're few documents about it, and many of the links on SF.net home page is 404 now.
The best I can found is XRCed Tutorial, however it is too primitive - so, does anyone have some idea for where can I find better documents about it?
Just a suggestion; have you tried wxFormBuilder? XRCed seems a little outdated (hasn't been updated for a while), and it does the same thing as wxFB. I've been using wxFB for a while in several projects and it's a life saver.
Alongside the already mentioned wxFormBuilder, I'm going to throw in wxGlade, as well. While I prefer wxFormbuilders GUI, I found it to be lacking in the available widgets. So I moved to wxGlade based on the amount of widgets it offers.
Both can create XRC files (and some other codes like C++ and python) and I think both are actively maintained. I think XRCed hasn't been updated since 2007.
For ease of use, I would go with wxFormBuilder. If you want to use various different widgets, for the moment, go with wxGlade. I don't know if wxFormbuilder is planning on incorporating ToggleButtons and the like in their future releases. It isn't in the one that I am using...

Is there an equivalent of Don Libes's *expect* tool for scripting interaction with web pages?

In the bad old days of interactive console applications, Don Libes created a tool called Expect, which enabled you to write Tcl scripts that interacted with these applications, much as a user would. Expect had two tremendous benefits:
It was possible to script interactions that otherwise would have had to be repeated by hand, tediously. A classic example was dialup Internet access hell (from the days before PPP).
It was possible to write scripts to test one's own interactive applications, programmatically, as part of a regression suite.
Today most interactive applications are on the web, not on the console. Hence my question: is there any tool that provides the ability to interact with web pages and web forms programmatically, much as Expect provides the ability to interact with console applications programmatically?
(The closest thing I am aware of is Chickenfoot.)
You might be looking for Selenium
I've used Selenium RC in conjunction with Python to drive web page interactions programmatically. This has allowed me to write pretty extensive user tests in which forms and inputs are driven and their results are measured.
Check out the Selenium IDE on Firefox (as mentioned above). It allows you to record tests in the browser and play them back, either using the IDE itself, or the Remote Control app.
Perl Mechanize works pretty well for this exact issue.
HTTPS and some authentication issues are tricky at times. I will be posting couple questions about those in the future.
I did a ton of Expect work in a former life and always thought Don Libes' Expect book was one of the best-written and most enlightening technical books I'd ever seen.
Hands down I would say that Perl's WWW::Mechanize library is what you want. I note above that you were having trouble finding documentation. There is good documentation for it! Look up the module's distribution on search.cpan.org and see what all is packaged with it. There's a FAQ, Cookbook with examples, etc. Plus I've always been able to get help on the web. If you can't get it here, try at use.perl.org or perlmonks.org. WWW::Mechanize's author, Andy Lester, is present on Stack Overflow. (He's also an all around friendly and helpful guy.)
I believe WWW::Mechanize also has a program that is analogous to Expect's autoexpect program: you set up a proxy process running this program as a server, point your browser to it as a proxy, perform the actions you want to automate, and then the proxy program gives you a WWW::Mechanize program for you to use as a base for your project. (If it works like autoexpect, you will certainly want to make modifications from there.)
As mentioned above, WWW::Mechanize is a browser (to be more exact, it is a web client or http client) that happens to be programmable. The last time I looked, there was even work in progress to make it support JavaScript.
In addition to Selenium, if you're doing the Ruby/Rails thing, there's Webrat.
