How do you move objects with mql4?

  • First Post: Jan 2, 2011 4:06am Jan 2, 2011 4:06am
Hi all,

I have some experience with mql4, however, despite trying various options, I cannot figure out how to move an object correctly with coding.

I am developing a grid indicator that creates horizontal, vertical and trend lines. The trend lines obtain their time coordinates from two of the vertical lines and I would like to be able to change the angle of the trend lines by moving one of the vertical lines. However, I haven't been able to get the vertical line to stay in the new location once moved - it keeps reverting to the original location. I have tried using objectget and 'move, but I must be missing something....

So, if anybody has the time and inclination to write some code explaining how to: detect that a vertical line has been moved and keep the vertical line in the new location, I would be very grateful.

Thanks in advance

without seeing any code it's hard to guess what you are doing wrong.

are you using objectmove correctly (i believe you need to set point ZERO). you might find it simpler to just use objectset and use the time1 property. you might also be specifying the time incorrectly (adding the wrong amount thinking in milliseconds instead of seconds for example).

if you successfully move it like you expect and then it magically moves itself back on the next tick then this suggests you are actually scripting it to move itself into a specific position somewhere in your script that you are overlooking.

Hi nubcake,

Here are some snippets of the code that I have at the moment - if you can figure out what I am doing wrong that would be very helpful....

The original locations are set with external inputs (the values are just for development purposes):
Inserted Code
extern double     Upper_Price=1.29280;
extern double     Lower_Price=1.27240;
extern datetime   Time_1=D'2006.05.05 00:00';

Then in start function I transfer the datetime values to variables:
Inserted Code
TimeCo_1 = Time_1;
TimeCo_2 = Time_2;

Next, I create the objects:
Inserted Code
ObjectCreate("LeftTimeExtent",OBJ_VLINE,0,TimeCo_1,0);
ObjectSet("LeftTimeExtent",OBJPROP_COLOR,Diagonal_time);
ObjectSet("LeftTimeExtent",OBJPROP_WIDTH,2);
ObjectSetText("LeftTimeExtent","Left time extent",Font_size,"TAHOMA",0);
   
ObjectCreate("RightTimeExtent",OBJ_VLINE,0,TimeCo_2,0);
ObjectSet("RightTimeExtent",OBJPROP_COLOR,Diagonal_time);
ObjectSet("RightTimeExtent",OBJPROP_WIDTH,2);
ObjectSetText("RightTimeExtent","Right time extent",Font_size,"TAHOMA",0);

All fine so far, but this is where I am stuck. This is my latest attempt to detect the move and fix the vertical line in place:
Inserted Code
if(ObjectGet("LeftTimeExtent",OBJPROP_TIME1)!= Time_1)
  {
    TimeCo_1 = ObjectGet("LeftTimeExtent",OBJPROP_TIME1);
    Print("TimeCo_1 = ",TimeToStr(TimeCo_1,TIME_DATE));
    ObjectMove("LeftTimeExtent",0,TimeCo_1,Upper_Price);
   }

The print function confirms that the objects datetime has changed, but the line still reverts to the original location - Time_1

You mentioned using objectset - as I understand it, it will only accept double values, so I guess that would require a calculation to determine the time difference and conversion to double?

I hope the above provides enough info' for you.

Cheers

you arent updating timeco_1. you read it in, then print your statement, then set a new object position to whatever upper_price is. timeco_1 will never change value so each time the test runs you will keep resetting the position to upper_price.

at least, that is how i currently read it.

also, i have never used objectmove before, so i think what you said is correct if my new assumption on how objectmove works is correct... basically, just ignore my suggestion on objectset and continue to use objectmove if you are satisfied it works as you expect and are comfortable with it.

actually, i think i just confused myself.

i think what you WANT to do is store the last position of your vert bar, and then simply test if it is no longer in that position at which point you update the variable keeping track of it's time1 and you also update the trend object.

if this is correct then the way you are going about it seems convoluted. i might simply not be seeing it correctly in my head, though, so don't take my word for it and you might be right.

Yes, what I want to do is manually move the vertical line on the chart and for the indicator to detect that the object has been moved and to store the new datetime so that the vertical line stays in the new position. At the moment, if I close the terminal and open it up again, the vertical line reverts back to the original location that it was created at - I can't figure out how to make the new datetime value persist.

OHHH well i don't think you said THAT.

easy. look up global variables. as long as you don't wait something like a month (can't remember, but something like that) before accessing the global variable it will be available regardless of if you shutdown or not. after the month, or however long it holds the global variables, has expired without you reading the value or setting a new value mt4 simply deletes it automatically. as your indi is likely going to tag the variable each tic that is not an issue.

pseudocode
Inserted Code
t1 = time[0];

if (!globalvariablecheck("myvert1time1")) t1 = globalvariableget("myvert1time1");

vert1t1 = objectget(vert1,time1);
if (vert1t1 != t1) t1 = vert1t1;

globalvariableset("myvert1time1", vert1t1);

updatetrendlinepositions;

... etc

something along those lines.

i think you might be misunderstanding what you are trying to achieve with what you are storing, reading, setting etc with all the different variables etc.

as you have given a bit more description of what you are trying to do you can still probably get around it easily enough without using global variables... but there is stuff you aren't revealing so maybe you require it and maybe you don't.

you can probably get away with just doing like i said in the previous post

store the last position of your vert bar, and then simply test if it is no longer in that position at which point you update the variable keeping track of it's time1 and you also update the trend object.

set your variable you are storing your 'last known time1 value' to 0 or some bogus data, and this will force it to update and set everything up correctly according to the positions of the actual vert object.

Inserted Code
datetime t1 = 0;

start {

  vert1t1 = objectget(vert1, time1);
  if (t1 != vert1t1) {
    t1 = vert1t1;
    updatetrendline;
  }

}

i'm a bit tired. my posts are getting loopy.

the global variable is for if you somehow require storing the data whether you keep the indi loaded or not. otherwise, you don't need them and can just test the objects time value against a variable you use as reference. if they differ then you need to update the value and update the trend object properties.

until you move the vert object then the stored value will match objects value and nothing will happen... however, what you probably ACTUALLY want to do is simply update the trendline each tick anyway, as this will stop someone from messing with the trendlines position.

if you simply update your trendline each tick then no matter how much the user messes around with the object it will always correct itself.

Thanks nubcake, I'll read up on global variables - I assume that I will need to incorporate a unique identifier into the coding so that each instance of the indicator has a unique global variable?

Thanks for your help!

i have a sneaky suspicion you have gone about this all wrong and should just update the trendline each tick. if you NEED to know that the vert object has been moved so as to perform some OTHER scripting functions as well then so be it, else if it is only to know that you need to update the trendline then this is a false conclusion as you don't actually need to know if they have moved or not and should just update the trendline regardless and in this way it will always be correct and will simply take care of itself.

anyways, i'm confused as to what you are trying to achieve so i am probably leading you astray.

When completed, the indicator will draw diagonals/trend lines through the grid boxes. The time coordinates for the diagonals/trend lines will be taken from the "left and right time extents" vertical lines.

I want to be able to change the angle of the diagonals/trend lines by moving one of the vertical lines. So for example, I might move the "right time extent" vertical line 1 box over to the right and thus reduce the angle of the diagonals/trend lines. If I do move it, I want the vertical line and diagonals/trend lines to persist in the new locations rather than reverting. Does that make sense?

This chart indicates a typical pair of diagonals before moving the "right time extent":

is it safe to assume those other vertical lines are standard chart period separators or some other indicator and have nothing to do with this?

from what you have shown it appears you can just do what i've said and simply recalc the trendlines each tick. the scripting required to test and check for a moved vertical line is far outweighed by the fact that recalcing each tick is quick and easy and costs no cpu time.

if you move one of the vertical lines, and then it moves back, then you must be setting it's position somewhere in the script and you are overlooking this piece of code due to staring at it too long. the only way an object can move is if you move it yourself or some script moves it programatically.

maybe the wrong questions have been asked... tell me this, when you say you want it to retain it's position do you mean in terms of the chart datetime position it gets set to, or do you mean in terms of the position 'on the screen'. i.e. if a new bar begins are you actually wanting the position of the vert objects to creep forward a bar as well? is that where things are falling down?

In answer to your question, I mean in terms of the chart datetime - I have probably made a boob somewhere but can't see it at the moment - I'll call it quits for today.

Thanks for all of your suggestions so far.

No, I still cannot figure out how to do this...

I am obviously missing something basic here - when I move the lines, they retain their new location - incoming ticks are not causing the vertical lines to revert. However, when I close the terminal and then open it again, the vertical lines are back at their original location. I have added an additional set of external datetime variables which allows me to set the cycle lines and vertical lines independent of each other, which is fine. But, I would like to know how to do this by manually moving the vertical lines - any suggestions welcome...here is my code to date:

Hi sangmane,

Thanks for replying - I had tried 0 and 1...and all sorts of other things to no avail. I forgot to swap it back to 0 before posting the code - oops!

I have been speaking to nubcake about it, and he believes that the issue that I have is due to the fact that I create the original vertical lines using external input datetime variables for the coordinates. Therefore, whenever I open up the terminal, the vert' lines revert to the external input datetime variables as the coordinates of the vertical lines that have been moved are lost when the terminal is closed. He has suggested that I use global variables to store the new coordinates for the moved vertical lines - makes sense.

Do you have any other ideas?

Hi sangmane,

I thought your problem was why the vertical line didn't move back to the predefined time (Time_1) after you moved it manually.
With your previous code, if you move the vert line manually, it won't revert back to its initial position. But if you apply my correction, the line will revert back.

I haven't done a good job explaining...here is what should happen;
1) add the indi to chart;
2) indi creates horizontal lines, cycle lines, "left and right time extent" vertical lines and diagonals (not coded yet) which use the time coordinates of the "left and right time extent" lines;
3) I manually move either the left or right time extent line and the indi then redraws the diagonals based on the new time coordinates of the "left and right time extent";
4) the vertical lines and diagonals should then remain fixed in these new positions regardless of incoming ticks and closing and opening the terminal, unless I move one of the "left and right time extent" lines, in which case, back to step 3.

However, as nubcake has explained to me, the new time coordinates will be lost when the terminal is closed, unless they are stored in the global variable.

Does that make sense?
