Grover, I see that GRANT and I were both happy to see that you made a
Plot text that would work without loops.
My only problem with plotshapes , is that Amibroker only allows the use of
digits 1 through 9.
I want to be able to plot up to the number 1000. I would use c1 for the
number 101, c2 for 102, 2c1 for 201, 2c99 for 299, and so on.
If plotshapes can be made to count to 1000 using the above method, then I
could continue using plotshapes, however, I would still
like to know how to use plot text using a very simple
format.
Grover>Then we show the actual Close price C with Lastvalue(C). We have to
say
lastvalue © because c is an array, and the function needs a number, not
an array.
dr is a dark red rangebound CCI plot line in a custom indicator
window, therefore it is an array.
br is a brown rangebound CCI plot line in a custom indicator
window, therefore it also is an array.
When the condition is such that dr>br, then a one is returned.
When dr is NOT >br, then nothing is returned.
dr>br means that the darkred CCI line plotted on the custom chart
is above the brown line., and puxgn=Cross(pu,gn);
Dips and tops are as shown below.
bkdip=bk>Ref(bk,-1) AND Ref(bk,-1)<=Ref(bk,-2);bktop=bk<Ref(bk,-1) AND Ref(bk,-1)>=Ref(bk,-2);
Therefore, since Buy 9 is either a one, or a zero, and not an array, plottext
should be able to do what I am looking for, right??
Below, is the exact code and plotshapes that I am now using.
seq9=dr>br AND
br>pg AND pg>pu
AND pu>yl AND yl>gn AND yl>bk AND bk>rd AND bk>wh AND rd>bu AND wh>bu AND bu>dg;
dps9=dgdip;
xes9=Sum(ylxgn AND
puxgn,2);
tps9=Sum(gntop AND
putop AND Sum(rdtop
AND whtop AND bktop AND yltop,2),3);
Buy9=seq9 AND dps9
AND xes9 AND tps9 AND xes9;
PlotShapes (IIf(Buy9,shapeDigit9+shapePositionAbove,shapeNone),colorRed);
Below here is the Grover plottext code loaded with my custom codes in order
to make it really clear what I am trying to accomplish.
IIf (Buy9,PlotText("\nBuy9"+"Buy9="+LastValue(Buy9),BarCount,LastValue(Buy9),colorred),0);
This syntax did not cause an error, but I saw nothing
appear in the coustom indicator chart pane. Ron D

Subject: RE: [amibroker] Simple plottext
format
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 © 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 ) );
