I would like to use an ma difference in my filters...but get errors below:
set{maDiff, ma(10)-ma(50)}
maDiff has been increasing for the last 2 weeks
Also can I use ema instead of ma?

siliconhippy,
Sometimes you have to use "minus" instead of "-" to do subtraction. I am not sure why that is. I have also noticed that you can sometimes do more "set" operations by playing with "-" and "minus".
Just a thought but another way you could write the same filter is:

siliconhippy,
Just as another thought (which may help in the futire), you may need spaces around your minus sign. It doesn't look like there are any.

cegis,
Sure. Got the same feedback from TomB. Now just wondering why they haven't rectified such an obviously discomforting bug so far...

siliconhippy,
Not sure I'd call it a bug... It is pretty much "standard practice" with computers to use a space to delimit (separate) individual "words with meaning". By using space, it allows you to use variable names with a dash. I don't know if SF allows it, but you might be able to do something like set{my-vol, volume 30 day low}. Here, I wouldn't want to subtract...

cegis,
I see what you mean. But SF should make a note of it in description of the set command. Sometimes small things like these become big hurdles: after all SF is useful because it does not require programming experience like other advanced packages !
