I'm making a line of on-chart buttons that will launch specific functions and indicators. So far so good the buttons load an indicator when pressed and delete it when the button is unpressed. But I would like to add two more functions to the button but I'm doing something wrong and it doesn't work properly and I need some help. 1st - I would like the button do be able to detect indicator on chart an automatically set the button to "ON" state in case I will drag and drop the indicator from indicator list. 2nd - when I press the button it will launch an indicator popup window and we have 2 options; 1 - "OK" which will launch the indicator on the chart and the button will stay in "ON" state. 2 - "CANCEL" which will abort lunching the indicator but it will leave the button in "ON" state. I would like the button to go back to the "OFF" state just after I press "CANCEL". Here is a peace of the code for testing. #property indicator_chart_window string sButtonName1 ="B1"; string sButtonName2 ="B2"; const string IndiName1 ="X"; const string IndiName2 ="Y"; //-------------------------------------------------------------- color UnloadedColor=clrGray;
