How can I prevent the objects drawn with the indicator from disappearing after the terminal is closed and opened?[MQL5]

[ZiYaR1]

I press a button and at the end of various calculations objects are drawn on the graph. If I delete the indicator I delete the drawings with "ObjectDelete()" in the "OnDeinit()" function, it's fine. However, after drawing the indicator, I close and open the terminal and of course everything resets. It is nice to reset, but the disappearance of the drawings causes me to do the same calculation again. How can I prevent this? Is the "OnDeinit()" function causing this?

You delete them "in the OnDeinit." "Is OnDeinit causing this?" When in doubt, think!
