About drawing an colored K-line?

New comment
 
In mt4,can I mark a special K-line with special color?

e.g.

if 10000*abs(close-open)>=100,then
mark this K-line with bold-red
(or draw an arrow near it)

Thank you!
 
can You expose some picture for illustrate what You need?

programs:

lenth=10000*abs(close-open)
if lenth > 50 then
mark( "lenth");//or mark("dot")
end if
 
you should copy the urls of pictures into a new opened IE address.
 
this is the "long tail" k-line.

Thank you for pictures.
Yes, it is possible. Please look at Parabolic SAR indicator source code example (/experts/indicators/Parabolic.mq4).
Based on this cource code you can write custom indicator that will mark chart by described algorithm.
 
Thank you!
I should know how to do.
.........

I'm now just reading the Parabolic.mq4 source ......
 
we've recommended parabolic because this custom indicator draws arrows like objects. but htis one is difficult.
first learn simplest indicators
 
I see.
I must study from begin.
Thank you.
 
I study the sample of Parabolic.mq4 and successfully change it to my own indicator(as show below),not very difficult.
How happy I am!
wonderful!
