Performance issue while loading graphs

[Anonymous]

I am facing an issue with while loading a certain graph that calculates the outstanding count and the aging of a ticket. I have used the concept of Generating missing dates for calculating the missing dates. As a result the script becomes heavy

This is the script that i have used to calculate the aging and outstanding .  So I referred to your blog to optimize the speed. I ran the memory file through the Qlikview optimizer and found that the most consuming memory is the creation of reference open dates. I have pasted the memory distribution pie charts below the script.

Although i have tried to use preceding load, set anaylsis in the expression and flags the graphs are taking a very long time to load. Is there a way to improve the performance of the graphs and is there a way for me to optimize the below script? Can you please suggest what I may be missing out so that the speed of the graphs is improved?
