For experts only,
Hi there,
How to make MetaStock draw an horizontal line at the Close of the day when a 21-day EMA crossed above the price and stay flat until the 21-day EMA crossed below the price when again, it will stay flat until it crosses above the price?
All I know is
If(cross(Mov(c,21,E),c),c,if(cross(c,Mov(c,21,E),c, ???))
With this simple formula I get a line that follows the prices but does not stay flat until the opposite condition is met.
HELP ….

Hi Wabbit,
Thanks for replying.
I know most of Metastock functions including ValueWhen, but I can't make it work.
If(Cross(Mov(C,21,E),C),C,If(Cross(C,Mov(C,21,E)),C, ValueWhen(1,Cross(Mov(C,21,E),C),21)))
This formula plots an indicator, but not a horizontal line on the chart itself, line that should change when the opposite incident occurs.
I know it’s more than the simple formula above I was able to come up with.
This is why I ask the help of experts …

Break the code up into parts, using variables: Code:
data:=CLOSE;
MA:=mov(data,21,e);
CrossUp:=Cross(data,MA);
CrossDn:=Cross(MA,data);
{plot}
if(barssince(CrossUp)<barssince(CrossDn), valuewhen(1,CrossUp,data),valuewhen(1,CrossDn,data));
You can neaten this up with initialisation functions, but see how you go with this first. wabbit [:D]

Well, well, well, Wab, this is big science for me, but now, because of you, I know more than yesterday.
Thanks.

There is no information in my post that cannot be found in the MS User Manual and the free Equis Formula Primer.
