Hi L V,
Well when I copy your code into the formula editor and try to apply it I
get errors and no chart until I comment out everything from if(arrows) to the
end.
Then I get a line plot of the closing price (which is what your code
specifies) and opening the parameters menu, I have all the parameters for
Price Field color style and Display arrows.
I doubt that this is what you were aiming for, but that's what you've
got. If you wanted a MACD, then you must specify MACD code in the
formula you are adding to a pane. I think you are working with just a
snippet of code, not the entire code.
You could overlay this snippet on a macd formula, but I don't know what
that will accomplish as long as you are plotting the price field.

Parameters
Thanks
Mr.Patrick for your time.
I did click reset button nothing happened.
I
saw the code in edit formula window by right clicking on the pane.It shows
exactly what I have given above. I have not given any separate code for MACD.
All that is there what is written by me above. I hope it utilizes inbuilt MACD
code.
Thanks regarding date ranges explanation.

Hi L V,
An addendum to my last post. If resetting the parameters did not solve
your problem, then check on the following items.
Are you certain that the chart you are clicking on is using the formula
you modified? If you had an existing chart open, then modified the
formula via right mouse click -> edit formula, then saved that formula to
custom folder, the original chart you had open may not be based on the
modified formula. To check either open the chart formula again to see
if it is modified, or open the parameters menu, -> Axes & Grid and
examine the file path under Miscellaneous. If it is not the modified
formula, then add that formula to a chart pane.
Another possibility is that the macd code you are
applying doesn't use the terms Color or style. The built in MACD I
have doesn't, instead it uses MACD Line Color, MACD style, etc. Of
course, I may have modified this code long ago and forgotten I did. If
you still have problems, post the entire macd code you are using, for
examination.
As to running an AA (scan, exploration, backtest) on a specific date
range, just set the dates in the from and to boxes and click the radio
button next to from. If you want the last date in your database
quickly, in the to box, click the down notion to open a calendar and
click on the red square at the bottom next to Today: (date of last update in
data).

Hi L V,
Did you also click on the Reset all button at the bottom of the
parameters screen?

Subject: [amibroker] Doubts about
Parameters
I have copied A Parameter example script as AFL in
customs folder given as below.
_SECTION_BEGIN("MACDSignal");
Buy = Cross(MACD(), Signal() );
Sell = Cross(Signal(), MACD() );
pricefield =
ParamField("Price Field", 3);
Color = ParamColor("color",colorRed);
style =
ParamStyle("style",styleLine,maskAll);
arrows = ParamToggle("Display arrows", "No|Yes",1);
Plot(pricefield,"pricefield",Color,style);
if(arrows)
{
PlotShapes(Buy*shapeUpArrow+Sell*shapeDownArrow,IIf(Buy,colorGreen,colorRed) );
}
_SECTION_END()
But when I open parameters window, I get parameter for
pricefield only.
1) What is to be done for getting all
parameters?
2) If I want to test only between some data say from 1
Jan 2010 to last trading day in scanning how should I modify this?
