Chart cleaner

This is a panel consisting of two buttons. Allows in one click to clear the chart from unnecessary graphic objects. The panel is made in the shell of the indicator.
By default, the "Delete 1" button deletes all deals-arrows and trend lines connecting them. The "Delete 2" button deletes all news icons. But, if necessary, you can delete other graphic objects by changing the prefixes in the menu.

Input parameters:

•      Prefix_1 The first few characters from the name of the objects to be deleted.
•      Prefix_2 Same for second button
