Ron,
You are not the only one with problematical brain gaskets!
Here is some simple plottext code: I pasted in some other code to insure
that it works.
PlotText(" "+" C= "+LastValue(C),BarCount,LastValue(C),colorBlack);
PlotText("\n "+" V= "+LastValue(V),BarCount,LastValue(C),colorBlack);
Here is the deal.
The first line shows the closing price just to the right of the last bar on
any chart.
The second line shows the Volume just to the right of the last bar and one
space below it.
Now look at the construction of the first line, and the second line has the
same construction. So we will look only at the first line.
At the beginning of the first line after Plottext, the spaces in quotes say
I want that much space to the right.
Then we print "C= "
Then we show the actual Close price C with Lastvalue(C). We have to say
lastvalue C because c is an array, and the function needs a number, not an
array.
Next we want the X, and Y position. They have to be numbers also, not
arrays. So, barcount is a number, Good, that takes care of X. Now, how
high is it on the screen (in dollars). There we use our old buddy
Lastvalue(C) again.
Finally we say what color.
Oh, and one more thing: On the second line the \n says put the second line
one space below the first line stuff.
Final item: watch out for arrays, we need numbers!!

Subject: [amibroker] Simple plottext format
I would like to be also be able to use plottext(); in the same simple AFL
format that I use for plotshapes.
The plotshapes that I have pasted below works fine, and it is done with AFL
that I understand.
PlotShapes(Buy*shapedigit1+shapePositionAbove,shapeNone),colorred)
I have never been able to figure out how to make plottext work because I am
not capable of understanding the help manual explanation of plottext();
There may be others like myself who would like to be able to plot text in a
chart using the same simple format that I understand, and that I use for
plotshapes. I have pasted the Plotshapes() and PlotText() formats below as
an example of the simple kind of format that I am looking for. Obviously
these formats don't work.
PlotShapes(IIf( Buyb,PlotText("buy one"),0));
PlotText(IIf( Buyb,PlotText("buy one"),0));
This description from the help manual is way beyond my knowledge, and I have
no need to spend a lot of time understanding loops because I don't need
them, and I don't want to blow one of my brain gaskets trying to learn how.
Unless, of course, someone has previously explained in very detailed english
how to understand this help manual explanation of plottext(). Ron D
Plot(C,"Price", colorBlack, styleLine );
Plot(MA(C,20),"MA20", colorRed );
Buy=Cross( C, MA(C,20 ) );
Sell= Cross( MA( C, 20 ), C );
dist = 1.5*ATR(10);
for( i = 0; i < BarCount; i++ )
{
if( Buy[i] ) PlotText( "Buy\n@" + C[ i ], i, L[ i ]-dist[i], colorGreen );
if( Sell[i] ) PlotText( "Sell\n@" + C[ i ], i, H[ i ]+dist[i], colorRed,
colorYellow );
}
PlotShapes( Buy * shapeUpArrow + Sell * shapeDownArrow, IIf( Buy,
colorGreen, colorRed ) );
