Gerard, the other way is to use the Favorites tab within the help files. I
use this to go quickly to the AFL lists, AFL reference manual etc
When you find a useful page, add it to your favourites list
Cheers,
Graham

Subject: [amibroker] Newby...If You are as I...(you poor unfortunate)
Friend,
If you are as I,
Challenged IQ-ally,
Memorially, Mathematically, Conceptually,
To name but a few,
Well this may interest you.
You see I was damn sick of wasting time finding info. Continually hitting
the help button and ploughing thru page after page of the manual. Talk about
frustrating. Half the time I'd previously found what I was now
looking for and not couldn't I remember it, I couldn't find it again!
A flash of inspiration suggested I use Indicator Builder to create a readily
accessible source of stuff I regularly use.
What you see underneath is a straight copy & paste from an IB pane of mine
named A INFO (that name keeps it at the top of the Indicators list).
In my custom A INFO indicator I keep easy to get at;
AFL numbers of the colours I use.
AFL numbers of the chart styles I use.
AFL formuae I can copy/paste until I get to remember them.
All Kinds of other guff I consider useful.
This is all arranged in descending order of useability/complication, for me
that is. I mean when is a drongo like me ever gunna use;
_TRACE - print text to system debug viewer
Yeah right.
I dump stuff when I am finally able to remember it.
NB.
PLEASE don't do a straight copy/paste of my file (I sure as hell wouldn't
trust me to be correct), but create your own. Your needs will be different.

// A INFO
// COLOURS
5=green 19=darkgreen 4=red 24=darkred 6=blue 21=darkBlue
7=yellow 1=black 2=white 25=orange 28=Teal 38=Violet
// CHART STYLES
1-line 4-thick 2-histogram 8-line with dots 16-no line
32-semi-log scale 64-candlestick 128-bar 256-styleNoDraw
512-staircase (square) 1024-middle dots for staircase 2048-no
rescale 4096-no value label 8192-point AND figure 16384-wide
histogram 32768-styleOwnScale 65536-styleLeftAxisScale
You can combine some styles but NOT all make sense, for example (64+1)
(candlestick + line) will result in candlestick chart (style=64 )
// COPY / PASTE SAMPLES
// To graph a (MA) Moving Average (6=Colour, 1=Chart style, see above)
insert-
Plot(MA(C,30),"ma",6,1);
// To scan for a MA Crossover, insert- Buy=Cross(MA(Close,3),MA(Close,18));
Sell=Cross(MA(Close,18),MA(Close,3));
// To scan for an Indicator Cross, insert-
Buy = Cross( RSI(), 30 );
Sell = Cross( 70, RSI() );
/*To add a Title, insert */ Title=Name()+ "Put name here";
/*To increase the no of Graphs in a pane, insert */ MaxGraph=10;
/*To squash graphs into Indicator pane, insert */ GraphXSpace=5;
/*To add a Filter (Volume) to an Exploration, insert */ Filter =
Volume > 500000;
/*To add a Column to AA Exploration RESULTS, insert */ AddColumn( Close,
"Closing price", 1.4 );
/*To add FULL NAMES to AA Exploration RESULTS, insert */
AddColumn(C,"C"); AddTextColumn(FullName(),"NAME");
/*To put an Indicator on main price chart. Right click on price chart select
edit formula AND paste your formula on the very top line above the
//--Indicator-End-- line. eg. */
Plot( WMA( Close, 20 ), "WMA20", colorRed );
