Hi,

just wondering if its possible to include an option which changes the width of the line being drawn? so that i can make it thicker? :?: :D

Can someone, please, test this indicator thoroughly?
It seems to struggle...

It is very slow to load, that is to say, it doesn't spread itself over the price action. One has to drag the chart back manually to actually make it draw itself (especially with a period greater than 100).

Also, is there a limit as to how many Non-lag MAs can be planted on one chart?
Once I load 10 of them they seem to kill Marketscope, it literally freezes.

I have already posted a request for a multiple non-lag indicator.
Do you think multiple non-lag MAs would work better if made into one indicator? Would it be easier for Marketscope to load?
