I don't think you can automatically make Metastock draw vertical lines..... but you can always program an indicator to do such things: x:= H; y:= L; If(x>HHV(H,20),1,If(LLV(L,20)>y,-1,0));

Correct Formula: I have a problem of cut and paste. Everytime I cut and paste, the formula becomes mixed . I don't know why. So now I cut and paste and then type out the forumula , hope it will appear correctly. If not , I don't know how to put in this forum correctly. nh:H>Ref(HHV(H,21),-1); nl:L

Hi, The forum has an issue of showing the sign "smaller than" and this is why you probably cannot paste it... Don't worry I understand what you are trying to do... Happy trading :) VT

Hi VT, I understand that there is a way to change the color of the price bar . I am thinking instead of the 20day high and 20 day low indicator, everytime it hit a 20 days high I like to change the price bar to blue and everytime it hit the 20 day low , change the price bar to red. I understand that there is a highlight formula for the price but just cannot get it. Would you be kind enough to supply the formula the color change of price bar. many thanks

Hi

as I remember there is no function to change the color of a line for a specific area. You can only change the color for the whole line. Beside this is only possible manually (and not from any formula)

But you can output 2 different lines (variables) and set alternatly one or the other to 0. then manually change one line to one color and the other line to an other color.

The other possiblity is to create an expert advisor which is possible to show you such events with colors or special signs...

Thanks vienna, you are right. I read in the manual that there is a possible way to change the price bar color by highlight. By itself, metastock seem only can accept binary output. i thought by changing color would be more visible. thanks for the assistance. Hope others could enlightened more if they knows.

To highlight a Bar for given conditions, you need to use the formula in EXPERT under the tab "Highlight". This should do what you need. I am a novice myself and prone to err, but no harm in giving it a try

Nhl:=If(H > Ref(HHV(h,20),-1),1,If(L < Ref(LLV(L,20),-1),-1,0));

now open an expert, click on the highlight tab,create a new highlight call it new highs

paste this formula

Nhl:=If(H > Ref(HHV(h,20),-1),1,If(L < Ref(LLV(L,20),-1),-1,0));
Nhl=1

create another highlight,call it new lows

Paste this formula

Nhl:=If(H > Ref(HHV(h,20),-1),1,If(L < Ref(LLV(L,20),-1),-1,0));
Nhl=-1

you have to use a space before and after the less than sign

Nhl:=If(H > Ref(HHV(h,20),-1),1,If(L < Ref(LLV(L,20),-1),-1,0));
Nhl=1
