Hi all pro coders, Im Phong & a newbie to MQL4. Im learning The problem is that Im trying to code a simple horizontal line on mainwindow & It gets value from Input properties, when the tick comes the code will check if I move the line to new position & obtain new value. So when i change timframe the horizontal line will not be set as input value anymore, it should be kept at new value. Could anyone show me the ideas to do that! or Functions to research/ codes ...??? Simple lines of code im trying...:/ I would be very grateful Thanks...

{quote} You are deleting the line at deinit ... so each time you switch TF, the indicator has to redraw it from scratch. So replace your deinit function by the below: void OnDeinit(const int reason) { if(reason == REASON_REMOVE || reason == REASON_PARAMETERS || reason == REASON_RECOMPILE) ObjectsDelete(0,"LevelLine"); } And also add the following before creating the object: if(ObjectsFind(0,"LevelLine") == -1)

As Wanderer says you could use Global vars. Updated as per request..... Sorry but no time to continually update. Up to you now unless you are really stuck. M. {file}

{quote} Hi, Have a look at global variables. Save the value as a global variable and read on each Init(). Delete the variable when removing the indicator. GlobalVarialSet() GlobalVariablGet() etc. Cheers
