I haven't been able to find a symbol/font combination that does a better job of
creating the horizontal lines to mark the open & close. As you note below, the
current symbols (Box drawings light down and left, light down and right) will
cause problems if the open or close value equals or is close to the low value
(which, as Henry points out, is all too frequently the case currently!)
The following is not as clean, but will not give "incorrect" results in some
cases:
plot_ohlc3=: 3 : 0
''plot_ohlc3 y
:
hl=. 1 2{y
oc=. 0 3{y
ntics=. {:$hl
pd 'reset'
pd 'xticpos ',": i.ntics
pd 'pensize 3'
pd 'symbolfont Arial 11'
pd x
pd 'color green,red'
pd 'type symbol'
pd 'symbols ',u: 9658 9668
pd oc
pd 'color blue'
pd 'type hilo'
pd hl
pd 'show'
)
