Greetings all. I'm just learning to code and have few questions. Can someone tell me please how to do this thing;
1- How to prevent my custom indicator being duplicated? If it's already on the chart and I will drop it on to the chart again, I want it to detect the first one and abort launching the second one with the same name.
something like this: but working :)
2 - How do I detect if there is more than one indicator with the same name on the chart?
3 - How to write an "if" statement to do something if indicator "x" is not present on the chart?
Something like this: but working :)
4 - Is there a way to put keyboard event (F11 - full screen) into code? To make my custom indicator be able to detect when full screen is on just like with "chart scale" ChartGetInteger(0,CHART_SCALEFIX); ?
