return series

[eurostoxx]

so i am been using the amVWAP efs by alexis, which is a great resource. I wanted to make a few adjustments

1) add 2 VWAP lines, one for the overnight session and one for the primary session
2) (which I have commented out b/c it was using too much CPU) A simple study that alerts if price has been above VWAP for more than XX mins.

I did this, but now when I run the script, it is a real hog, and using up a lot more resources than the original script. I am sure I am not calling something in the most efficient manner. Can anyone suggest anything..

in the original code, the return statement is just getSeries(xVWAP) but since I added another plot, I made an array, but to me this seems to be taking up a lot of resouces

thanks

see code
