Hi Happy,
Can you please tell me what (AFL) system is this? it gives almost same signal as KPL.
Regards.

}

uses layering

one could remove the last param in plot lines where there are 4 parameters after the style parameter

e.g.
change
Plot(Ref(Buy_valid,0),"",ColorRGB(0,0,100),styleHistogram|styleDashed|styleOwnScale|styleNoLabel,0,0,0,-1);

to

Plot(Ref(Buy_valid,0),"",ColorRGB(0,0,100),styleHistogram|styleDashed|styleOwnScale|styleNoLabel,0,0,0);

however this would remove layering so not sure of final look.

final look could be kept the same if less layer Plot lines are before ones with smaller layer parameter

like plots which have param 0 in that last value is before ones that have -1

but that will have to be seem in detail in the context of the logic

Hi,

Are you all so crazy to solve this problem on Ver 5.20 which created in 2009.
How much changes had it been in 4 years.

It is easier upgrade to latest version then wasting time of this issue.

KelvinHand · Oct 8, 2013

worldastro said:

Version 5.20 do not have

ColorBlend() - AmiBroker 5.30 Release Candidate

Plot() do not had width, zorder parameters.:annoyed:
Zorder => AmiBroker 5.22 bug fixed
Width => Amibroker 5.52 Release
