please how to make label for an Horizontal Line Object
The OBJ_TEXT object needs a Price and Time, from the png you posted it seems to use the current bar time for it's time (Time[0]), then you can use the horizontal line Price1 value for its Price.
Something like this . .
ObjectCreate("ligne1label", OBJ_TEXT, 0, Time[0], ObjectGet("ligne1", OBJPROP_PRICE1) );
Hello RaptorUK ;
thank you very much it works
I have just 2 questions about that because I know that it's possible to get the value mainly the price by ObjectGet function and I review all the constant like (OBJPROP_TIME1, OBJPROP_PRICE1)
but is it possible to get instead of those constants another value for example : a value of my personnal indicator (MACD or RSI etc ..) . I mean, I would like to create an object (Text ) basing on indicator value . is it possible ?? if yes, How ??
my last question is, you know on this indicator I make a comment like this on the code
int init() { //---- indicators Comment("RectangleTarget"); //---- return(0); }
but when I delete the indicator the comment stay !!
on deinitialization function I do ike this to delete all objects
ObjectDelete("ligne1"); ObjectDelete("ligne2"); ObjectDelete("milieu"); ObjectDelete("hausse1");
but I don't know how to delete this comment ??
that's all !!
really thank you for your answer !!

To get the value of an Indicator you need to use iCustom https://docs.mql4.com/indicators/iCustom make sure you pass ALL the Indicators extern variables in the iCustom call.
Once you have the value returned from iCustom you can add it to your chart as a Text Object.
Yes, I see this function and it is very useful !! let me take a simple example to understand really how to attach an indicator value to an object
for example in my personnal indicator we called : histogramtrend the code is like this
//+------------------------------------------------------------------+ //| histogramtrend.mq4 | //| Copyright © 2011, MetaQuotes Software Corp. | //| http://www.metaquotes.net //| //+------------------------------------------------------------------+ //+------------------------------------------------------------------+ //| Histogramtrend2.mq4 | //| Copyright © 2011, MetaQuotes Software Corp. | //| http://www.metaquotes.net | //+------------------------------------------------------------------+ // represnete un histogramme des croisements #property indicator_separate_window #property indicator_buffers 3 #property indicator_color1 Black #property indicator_color2 Red #property indicator_color3 Green //--- input parameters extern int period1=13; extern int period2=7; //--- buffers double ExtMapBuffer1[]; double ExtMapBuffer2[]; double ExtMapBuffer3[]; // //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { //---- indicators IndicatorBuffers(3); SetIndexStyle(0,DRAW_LINE); SetIndexBuffer(0,ExtMapBuffer1); SetIndexStyle(1,DRAW_LINE); SetIndexBuffer(1,ExtMapBuffer2); SetIndexStyle(2,DRAW_LINE,STYLE_DOT,1,Green); SetIndexBuffer(2,ExtMapBuffer3); //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator deinitialization function | //+------------------------------------------------------------------+ int deinit() { //---- //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator iteration function | //+------------------------------------------------------------------+ int start() { int counted_bars=IndicatorCounted(); int limit ; //---- if(counted_bars>0) counted_bars--; limit = Bars-counted_bars; for(int i=0;i<limit;i++) { ExtMapBuffer1[i] = iMA(NULL,0,period1,0,MODE_EMA,PRICE_CLOSE,i); } for(i=0;i<limit;i++) { ExtMapBuffer2[i] = iMA(NULL,0,period2,0,MODE_EMA,PRICE_CLOSE,i); } for(i=0;i<limit;i++) { ExtMapBuffer3[i] = ExtMapBuffer2[i]-ExtMapBuffer1[i]; } //---- return(0); } //+------------------------------------------------------------------+
My target is to show on chart the trend of ExtMapBuffer3[i] if it is above 0 or not (if MM7 is across MM13)
so as you can write we can use iCustom function so according to this code we can write another indicator like this (I simplify )
// for example in my indicator personnal I write that where there is ExtMapBuffer2 SetIndexStyle(1,DRAW_LINE); SetIndexBuffer(1,ExtMapBuffer2); // in the new code indicator we can do // for example for M5 double M5 = iCustom(NULL,5, "histogramtrend",1,0);// here line index 1 review SetIndexBuffer double M15 = iCustom(NULL,15, "histogramtrend",1,0); double M30 = iCustom(NULL,30, "histogramtrend",1,0);
if it is like this my question is how to attach M5 - M15 - M30 value to an object because in the function ObjectCreate() there are more parameters constant like Price and time ??
and here I would like to show in Text the value of ExtMapBuffer2 in multi time frame via M5 - M15 -M30
in order to know if >0 we write the text where there is the value in green if <0 in red something like that (The text on the right ) :
https://www.mql5.com/en/code/9090
thanks a lot for the function to delete comment !!
You can create the Objects and then afterwards change their position, their text content and their colour.
So, ObjectCreate 3 times for the 3 objects, then ObjectSet to change the position OBJPROP_TIME1 & OBJPROP_PRICE1 (see https://docs.mql4.com/objects/ObjectSet & https://docs.mql4.com/constants/objects/properties ) and also ObjectSetText to set the text you want to show on screen (see your other thread) and finally you can set the colour . . .
color TextColor; if (value < 0) TextColor = Green else if (value > 0) TextColor = Red; ObjectSet("name", OBJPROP_COLOR, TextColor );
If this doesn't work when trying to set the colour you can do it when you set the text using ObjectSetText . .
Hello ;
I have many problem :( here is the code :
//+------------------------------------------------------------------+ //| MultiTimeframeTrend.mq4 | //| rahan | //| http://www.metaquotes.net | //+------------------------------------------------------------------+ #property copyright "rahan" #property link "http://www.metaquotes.net" #property indicator_chart_window //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { //---- indicators //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator deinitialization function | //+------------------------------------------------------------------+ int deinit() { //---- //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator iteration function | //+------------------------------------------------------------------+ int start() { // we get the value of custom indicator double MM5 , MM15 ; string name ; color Textcolor ; int counted_bars=IndicatorCounted(); // int obj_total = ObjectsTotal(); //---- // we try to get the value of custom indicator MM5 = iCustom(0,5,"histogramtrend",1,0); MM15 = iCustom(0,15,"histogramtrend",1,0); // we create an object Text // at the begin we attribute the price of the text as 0 // the problem is I don't know in the paramter the price1 // here we create the Text for the M5 if(!ObjectCreate("TextM5", OBJ_TEXT, 0, Time[0],0)) { Print("error: can't create label_object! code #",GetLastError()); return(0); } else // we change the value and the position { // we change the price or the value // here we can 't use ObjectSetText("TextM5",MM5..) because MM5 is double ObjectSet("TextM5", OBJPROP_PRICE1,MM5); // we change the position ObjectSet("TextM5", OBJPROP_XDISTANCE,10); ObjectSet("TextM5", OBJPROP_YDISTANCE,10); // we change the color if(MM5<0) Textcolor=Red; else if (MM5>0) Textcolor=Green; else Textcolor=White; ObjectSet("TextM5", OBJPROP_COLOR, Textcolor ); } // here we create the Text for the M15 if(!ObjectCreate("TextM15", OBJ_TEXT, 0, Time[0],0)) { Print("error: can't create label_object! code #",GetLastError()); return(0); } else { // we change the price or the value // here we can 't use ObjectSetText("TextM5",MM5..) because MM5 is double ObjectSet("TextM15", OBJPROP_PRICE1,MM15); // we change the position ObjectSet("TextM15", OBJPROP_XDISTANCE,10); ObjectSet("TextM15", OBJPROP_YDISTANCE,10); // we change the color if(MM15<0) Textcolor=Red; else if (MM15>0) Textcolor=Green; else Textcolor=White; ObjectSet("TextM15", OBJPROP_COLOR, Textcolor ); } //---- return(0); } //+------------------------------------------------------------------+
the first problem is I don't know if we get the value of the custom indicator like this and a simple question how it makes the update of this data ??
// we try to get the value of custom indicator MM5 = iCustom(0,5,"histogramtrend",1,0);
my second problem is the way to create the Text (object), when we create a rectangle for example, at the beginning we draw manually it so we can get its Time and price . but here we don't draw, we are just show the value by text
so I define the default value of Text as 0.
if(!ObjectCreate("TextM5", OBJ_TEXT, 0, Time[0],0))
after we try to change the value of the Text may be we can do : ObjectSetText("TextM5", M5, 10, "Times New Roman", Green); but we need String as a data type then MM5 is a double
so I use this function
ObjectSet("TextM15", OBJPROP_PRICE1,MM15);
for the position and the color I procede like that, I don't know if there are something wrong
// we change the position ObjectSet("TextM5", OBJPROP_XDISTANCE,10); ObjectSet("TextM5", OBJPROP_YDISTANCE,10); // we change the color if(MM5<0) Textcolor=Red; else if (MM5>0) Textcolor=Green; else Textcolor=White; ObjectSet("TextM5", OBJPROP_COLOR, Textcolor );
and after I carry on for the MM15 in using the same process
I don't know if we can use ObjectSet for Text Object because there is the function ObjectSetText()
thanks :)
How many buffers does your Indicator have ? how many extern variables does it have ? the first parameter you pass using iCustom ( https://docs.mql4.com/indicators/iCustom ) is the symbol, 0 is not valid for that, use NULL for the current chart symbol.
You can only use X & Y pixel values with text labels, for Text you have to use time and price
If you look at your other thread you will see how to convert a double to a string https://docs.mql4.com/convert/DoubleToStr
here is all the code of the indicator
//+------------------------------------------------------------------+ //| histogramtrend.mq4 | //| Copyright © 2011, MetaQuotes Software Corp. | //| http://www.metaquotes.net //| //+------------------------------------------------------------------+ // represnete un histogramme des croisements #property indicator_separate_window #property indicator_buffers 3 #property indicator_color1 Black #property indicator_color2 Red #property indicator_color3 Green //--- input parameters extern int period1=13; extern int period2=7; //--- buffers double ExtMapBuffer1[]; double ExtMapBuffer2[]; double ExtMapBuffer6[]; // double ExtMapBuffer3[]; double ExtMapBuffer4[]; double ExtMapBuffer5[]; //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { //---- indicators IndicatorBuffers(6); SetIndexStyle(0,DRAW_LINE); SetIndexBuffer(0,ExtMapBuffer1); SetIndexStyle(1,DRAW_LINE); SetIndexBuffer(1,ExtMapBuffer2); SetIndexStyle(2,DRAW_LINE,STYLE_DOT,1,Green); SetIndexBuffer(2,ExtMapBuffer6); SetIndexBuffer(3,ExtMapBuffer3); SetIndexBuffer(4,ExtMapBuffer4); SetIndexBuffer(5,ExtMapBuffer5); //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator deinitialization function | //+------------------------------------------------------------------+ int deinit() { //---- //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator iteration function | //+------------------------------------------------------------------+ int start() { int counted_bars=IndicatorCounted(); int limit ; //---- if(counted_bars>0) counted_bars--; limit = Bars-counted_bars; for(int i=0;i<limit;i++) { ExtMapBuffer3[i] = iMA(NULL,0,period1,0,MODE_EMA,PRICE_CLOSE,i); } for(i=0;i<limit;i++) { ExtMapBuffer4[i] = iMAOnArray(ExtMapBuffer3,0,period2,0,MODE_EMA,i); } for(i=0;i<limit;i++) { ExtMapBuffer5[i] = iMAOnArray(ExtMapBuffer4,0,period2,0,MODE_EMA,i); } for(i=0;i<limit;i++) { // histogram ExtMapBuffer2[i] = ExtMapBuffer4[i] - ExtMapBuffer5[i]; } for(i=0;i<limit;i++) { // ligne ExtMapBuffer1[i] = iMAOnArray(ExtMapBuffer2,0,period2,0,MODE_EMA,i); // 0 ; } for(i=0;i<limit;i++) { ExtMapBuffer6[i] = ExtMapBuffer5[i] - ExtMapBuffer4[i]; } //---- return(0); } //+------------------------------------------------------------------+
the most important is ExtMapBuffer2 and ExtMapBuffer1 because I would like to attach in main window if they are <0 or >0 . that is to say
if ExtMapBuffer2 > ExtMapBuffer1 then I show the value in green color
if ExtMapBuffer2 ExtMapBuffer1 then I show the value in red color
if ExtMapBuffer2 = ExtMapBuffer1 then I show the value in white color (neutral)
and I would make it for all time frame
oh yes, excuse you're right we must write the function like this
MM5 = iCustom(NULL,5,"histogramtrend",1,0); MM15 = iCustom(NULL,15,"histogramtrend",1,0);
yes I see, the way to convert double to string and I want to correct the code !! but I really insist on the way to create the Text ??
I change the code like this because we need 2 get 2 buffers for each time

about the position
but as you can see we don't see anything may be there is something or we must change the position
You have this in your Indicator . . .
extern int period1=13; extern int period2=7;
. . . you MUST pass values for these variables in iCustom.
Example . .
MM15 = iCustom(NULL,15,"histogramtrend", 13, 7, 1,0);

Hello ;
at the moment I have created an horizontal line without Label like that :
but I would like to have an indicator with label like that
http://img.ibtimes.com/www/data/images/full/2010/09/15/45438.png
the code is like this
but I don't know how to make the label on horizontal line that is to say : to mark ligne1 on the appropriate line
I try to make like this because there are a lot of Line
the problem is I don't know the parameters on ObjectCreate("ligne1label", OBJ_TEXT,??????); to make the label according my case !!
I try to inspire this code :
