How can I save trend lines, objects and my studies into the charts? If I save a template and then close the platform when I return, my studies are deleted from the charts.
When saving templates, the annotations (graphical tools and objects) are actually saved, but only for the opened charts before you saved the template.
What is not saved is, for example, when on you draw tools and objects on a chart, then you change the currency on that chart and do another analysis using tools and objects and then you decide to save the template before exiting. In this case the template will save the annotations on the current pair on that particular chart. It will not remember what you did (if you exit and then return back) on the previous currency pair, which you had on the same chart window.
