I wonder how do I permanently delete indicator from MT4 software?
Indicator, in my case Average True Range, is the original one and NOT a custom.
I would like to delete it from menu, so entirely from the MetaTrader Terminal 4 software and not only from a chart. This indicator is a total disaster, by far worst indicator ever seen - impossible to trade according to it, impossible to follow it, wrong data, no signals where to enter Short/Long online, no resources about this indicator, nothing.
I would like to get rid of it, but how do I delete it?
It is not a Custom Indicator, so I need help getting rid of it.
Bad news: there is no way to achieve this.
Built-in indicators are simply hardwired into the MetaTrader Terminal ( MT4 )
Good news: there is no must to launch it.
So, given no activation has taken place, all your wishes are met.

I'm using Optaplanner to automatically solve school timetables. After a timetable has been solved the user will manually change some lessons and will get feedback on how this affects the score via the following call:
scoreManager.updateScore(timetable);
This call takes some 200ms and will, I assume, do a complete evaluation. Im trying to optimize this and want to only pass in a Move object so that Optaplanner only has to recalculate the delta, like:
scoreManager.updateScore(previousTimetable,changeMove);
Is there a way to do this?
There really is no way how to do just a single move. You don't do moves - the solver does moves. You can only make external problem changes to the solution. You should look into the ProblemChange interface and its use in the SolverManager.
However, the problem change will likely reset the entire working solution anyway. And after the external change is done, you're not guaranteed that the solution will still make sense. (What if it breaks hard constraints now?) You simply need to expect and account for the fact that, after users submit their changes, the solver will need to run; possibly even for a prolonged period of time.
My solution is for VRPTW and I've created a Custom Move.
After a custom move has been tried (prior to being accepted), I would like to see a score breakdown of it (not just the score itself).
Where is a good location to use ScoreExplanation to see the detailed score breakdown? Eg. in my AbstractMove implementation somewhere?
I have TRACE mode on and can see the score. I've tried pulling it up upon the next custom move being run and it seemed to be working since it was retrieving the correct score from the previous custom move, but when I looked at the ScoreExplanation, it looks completely off (it doesn't add up to the score).
Score explanations are not designed to be used inside of a step, they are far too slow for that. You are free to use the ScoreManager API any time you like, but you will pay a heavy performance penalty if you do that on the solver thread or the move threads.
I'm building a student schedule generator and I need a way of producing more than one solution. Is there some way to save off feasible scores or scores of Xhard/Ysoft?
I need to be able to output more than one potential schedule, that way the student will have a choice for one schedule over the other if for whatever reason they don't want the "best" schedule (maybe they don't like one of the professors, maybe they don't want an 8am class, whatever)
My original idea was to save off all feasible solutions using the bestSolutionChanged event listener. The problem with this, is that once it finds a 0hard/0soft score, it ignores all scores after that, including scores that are equal.
Ideally I'd like to save off all scores of 0hard/-3soft or better, but just being able to save any feasible scores or force optaplanner to look for a new best score would be useful as well.
This is not a solution, but an analysis of the problem:
Hacking the BestSolutionRecaller is obviously not just a big pain, it's also behaviour we don't want to encourage as it makes upgrading to newer version an even bigger pain. So don't expect us to solve this by adding an easy way to configure that in the solver config any time soon. That being said, a solution for this common problem is clearly needed.
When a new best solution is found, it is planning cloned (see docs for definition) from the working solution (the internal solution in OptaPlanner). This allow us to remember that new best solution as the working solution solution changes. That also means the BestSolutionChangedEvents gets a plannng clone and can safely ship it to another thread, for example to marshal it to a client (presuming any ProblemFactChanges you create do copies instead of alterations), without being corrupted by the solver thread that modifies the working solution.
New best solution imply that workingScore > bestScore. The moment it instead does workingScore >= bestScore, we need far more planning clones (which are a bit CPU expensive), but we could then just send out BestSolutionChangedEvents for that too, if and only if a flag is enabled of course, because most users (unlike yourself) don't want this behaviour.
One proposal is to create a separate BestSolutionChangedOrSameEvent, next to the BestSolutionChangedEvent. This might not be ideal, because we need to be able to detect whether or not someone needs those extra planning clones.
Another proposal is to just have a flag in the <solver> config that switches from > to >= behavior for BestSolutionChangedEvent.

I'm trying to create a survey containing several slider-type questions, asking participants to select a point on a line to indicate their experience of different emotions. For example:
Not at all anxious -----------------------|---------------------Extremely anxious
These questions are meant to serve as visual analogue scales (VAS), often used in my field but typically administered via paper/pen. A digital VAS would be very useful for my research, but I have 2 problems with the Qualtrics format.
First, I need to hide the vertical slider until participants selects a point on the line (in effect removing any visual "starting point" that can influence responses). Second, I can't force participants to respond to every question, so I need a way to distinguish those who skip a question/don't answer (including code to check if the slider was displayed or not displayed when the participant chooses to continue to the next question might work, so that Qualtrics stores no response for that question if the slider is still hidden).
Thanks for the help! I'm not a coder, so I would really value any and all advice!
I've been using the Game State Management sample which has worked so far. I've hit a snag though: when Tombstoning, the screens are serialised; the only trouble is, the MessageBoxScreen has event handlers for Accepted and Cancelled.
What's the best way to serialise these? I did a bit of research on using Expression Trees but this seemed overly complex for what I wanted to do.
How do you serialise these? Or... What alternative approach do you use to save the state of a screen that contains delegates?
I'd definitely steer clear of attempting to serialize anything remotely resembling a lambda, or for that matter, named methods. Remember: you're storing state, and nothing else.
Depending on how far and wide your various assignments to these delegates are, you might be able to get away with maintaining a Dictionary<String, WhateverDelagateType>, serializing the keys and looking up the callbacks after deserialization.
Another thing to consider--I'm no expert, but reading between the lines it sounds as if you're working towards tombstoning a very temporary modal dialog. Do you really want that? You might be better off bringing your user right to the high scores table, or whatever follows your dialog, on his/her return.
I decided against this. I instead persists game flow as a kind of 'flow chart'.
The flow chart is declared in code and has properties 'LastShape' and 'LastResultFromShape'.
In my code, I rebuild the flow chart definitions each time, something like this:
flowChart.AddShape( "ShowSplash" );
flowChart.AddLine( "MainMenu", ()=>lastResult=="Clicked" || lastResult=="TimedOut");
flowChart.AddShape( "MainMenu");
flowChart.AddLine( #"ShowOptions", ()=>lastResult=="OptionsClicked");
flowChar.AddLine( #"ShowSplash", ()=>lastResult==#"TimedOut");
etc.etc.
The flow goes from the top down, so 'AddLine' relates to the last shape added.
After tombstoning, I just read the last shape and the last result and decide where to go in the flowchart based on that.
