I am sorry for these mistakes, they will be fixed: +DI is green by default,
-DI is red.

Yes, they are the same

Yes it should, but this seems to be a bug in AmiBroker.
If you want a different period for ADX/DMI you can enter the following
formula in Custom Indicator builder:
custom_adx_period = 16;
maxgraph = 3;
graph2 = pdi(custom_adx_period );
graph1 = mdi(custom_adx_period );
graph0 = adx(custom_adx_period );
graph2style=1;
graph0style=5;
graph1color=5;
graph2color=6;
graph0color=7;
title=name() + " - +DM" + writeval( graph2 )+ ", -DM" + writeval( graph1 )+ ", ADX" + writeval( graph0 );

It seems to be a problem with AmiBroker.

One thing that is important to understand is that
not every chart/indicator built-in is written using AFL.
Most built-in indicators are written in C compiled to native machine
code for speed. AFL is great but a little bit slower than native code,
so for performance reasons the basic indicators are implemented
in machine code.
Thank you very much for pointing out the bugs in AmiBroker.
They will be fixed in the next release.
