In this code, I am getting the Green and red candle Counts being overwritten and it's not clearly shown in the chart and it leaves out the first candles at the market open time..
Guys, I want the gren and red candle counts separately including the first candle at the market open time and i dont want the overwritten counts and I want the correct counts..I am just a beginner..Please help me on this one..Thanks..
plot(close)
t = ta.change(time('D'))
up = close > open ? 1 : 0
dn = close < open ? 1 : 0
a = 0.
a := t ? up : a[1] + up
b = 0.
b := t ? dn : b[1] + dn
label.new(bar_index, high, str.tostring(a), textcolor=color.blue, style=label.style_none)
label.new(bar_index, high, str.tostring(b), textcolor=color.blue, style=label.style_none)
As far as I can see your code should count up and down bars correctly, except that up bar is when close >= open.
In order for the values not to be overwritten and not to confuse you, you can delete the old labels on all bars except the first one.
Here is an example
//#version=5
indicator("Candles Up/Down Counts", overlay=true)
label upCountLbl = na
label dnCountLbl = na
upCounts = 0
dnCounts = 0
resetState = ta.change(time("1D"))
upBar = close >= open ? 1 : 0
dnBar = close < open ? 1 : 0
upCounts := resetState ? upBar : upCounts[1] + upBar
dnCounts := resetState ? dnBar : dnCounts[1] + dnBar
upCountLbl := label.new(bar_index, high, str.tostring(upCounts), textcolor=color.green, style=label.style_none, yloc=yloc.abovebar)
dnCountLbl := label.new(bar_index, high, str.tostring(dnCounts), textcolor=color.red, style=label.style_none, yloc=yloc.belowbar)
if not(resetState)
label.delete(upCountLbl[1])
label.delete(dnCountLbl[1])

So I have a ms access form with a bunch of a comboboxes in it. I want to change the background of the combobox to red if it's null and its past the end date of the project. I have attached my code snippet below. so far it's only changing the background color of the list, not the combobox itself. the code snippet is set to run during the form open event.
If Me.Combo1.Visible = True Then
If IsNull(Me.Combo1) = False Then
textsum = textsum + 1
totalcount = totalcount + 1
Else
totalcount = totalcount + 1
If Me.ProjectEndDate<= Date Then
Me.Combo1.BackColor = RGB(255, 0, 0)
End If
End If
End if
I want to let the user select multiple ROI's on a picture. I used a while loop. I paused and let the user select an ROI. After that the while loop would continue unless the user clicked another button on the toolbar to terminate the while loop. The code worked on single pictures. I made the code a function. When I looped and called the function in another script, it failed to proceed. I pressed Ctrl + C and it showed that "Operation terminated by user during uiwait". Apparently the uiresume didn't work.
Please let me know where the problems are. Thanks! My code:
% Below was basically a copy of the example given in R2014a.
% It created an interactive toolbar with 2 pushbuttons.
fh = figure('ToolBar', 'none'); hold on;
h_im = imshow(rgb2gray (I));
tbh = uitoolbar(fh);
[X_OK, map_OK] = imread(fullfile(matlabroot,...
'toolbox','matlab','icons','greenarrowicon.gif'));
[X_rect, map_rect] = imread(fullfile(matlabroot,...
'toolbox','matlab','icons','tool_rectangle.gif'));
% Convert indexed image and colormap to truecolor
icon_OK = ind2rgb(X_OK, map_OK);
icon_rect = ind2rgb(X_rect, map_rect);
% Create 2 uipushtools in the toolbar
% I introduced 2 variables, leave and draw, to facilitate the control of the
% later while-loop.
pth_OK = uipushtool(tbh, 'CData',icon_OK,...
'TooltipString','Toolbar push button',...
'ClickedCallback',...
'leave = 1; uiresume (gcbf)');
pth_rect = uipushtool(tbh, 'CData',icon_rect, 'Separator','on',...
'TooltipString','Toolbar push button',...
'ClickedCallback',...
'draw = 1; uiresume (gcbf)');
% The loop for ROI selection.
ii = 1;
% Maximum the use can select 30 ROI's.
while ii < 31;
draw = 0;
uiwait;
if leave == 1;
% If the user pressed "OK" button, leave will be 1.
break;
end;
if draw == 1;
% If the user pressed the "rect" button, draw will be 1.
h = imrect;
wait (h);
gui_Mask = createMask(h, h_im);
greyImg (~gui_Mask) = 255;
ii = ii + 1;
continue;
end;
end;
I saw someone used set/waitfor instead.
I tried to change to set/waitfor. Now it works both in the function and when the function being called.
But I still want to know why uiresume didn't work.
Windows "viewers" (like Windows Live Photo Gallery or Windows Photo Viewer) have not supported GIF animation since the days of Windows XP. The handiest way I know now to view animation of a GIF is to open it with MSIE -- but THAT, unlike Windows Photo Viewer, does not let me "scroll" through a directory to view other image files. It occurred to me that I could create a scripted HTML document that would perform that "scrolling" through the directory, but I don't know of a way to set it up so that by right-clicking an animated GIF file in my "Recent Items" (or elsewhere), and selecting "Open with...", that one of the options in that group would be the HTML doc I had created, to be opened in MSIE and given the name of the file I had right-clicked on (in the location.search property, for example), so that it would display THAT animated GIF initially, but then, by my script in the HMTL document, would let me scroll through the directory to view other image files as well. Also, I would want this option to be available for any type of image file, so that I could initially view, say, a JPEG file, but then subsequent "directory scrolling" could include GIFs or BMPs, etc. IS there a way to do that?
As the saying goes, "Don't get me started!" :)
I hadn't actually planned on having the batch write to the HTML file, but given that approach, I decided to put my javascript into a JS file, and have the batch write code that would reference it, thus:
#echo ^<html^>^<body onkeydown='kdn(event.keyCode)'^>^<span id='im'^>^<img style='display:none' src=%1^>^</span^>^<script src='c:/wind/misc/peruse.js'^>^</script^> > c:\wind\misc\peruse.htm
#start c:\wind\misc\peruse.htm
I found that the only way to handle the backslashes in %1 was to store it directly to an img src, as you did; however, I wanted more detailed code for the img than I wanted to write at this stage, so I set it to be invisible and placed it inside an id'd span for later elaboration by my script. It's nice to know about %~p1 but I don't really need it here.
And here is a rudimentary script (in peruse.js) for folder navigation that it calls up:
document.bgColor = 'black';
f = ('' + document.images[0].src).substr(8);
document.getElementById('im').innerHTML = '<table height=100% width=100% cellspacing=0 cellpadding=0><tr><td align="center" valign="middle"><img src="' + f + '" onMouseDown="self.focus()"></td></tr></table>';
fso = new ActiveXObject("Scripting.FileSystemObject");
d = fso.GetFolder(r = f.substr(0, (b = f.lastIndexOf('/')) + (b < 3)));
if(b > 2) r += '/';
b = (document.title = f.substr(++b)).toLowerCase();
for(n = new Enumerator(d.files) , s = [] , k = -1 , x = '..jpg.jpeg.gif.bmp.png.art.wmf.'; !n.atEnd(); n.moveNext()) {
if(x.indexOf((p = n.item().name).substr(p.lastIndexOf('.') + 512 & 511).toLowerCase() + '.') > 0) {
s[++k] = p.toLowerCase() + '*' + p
}
}
for(s.sort() , i = 0 , j = k++ , status = k + ' file' + (k > 1 ? 's' : '') , z = 100; (x = s[n = (i + j) >> 1].substr(0, s[n].indexOf('*'))) != b; ) {
x < b ? i = (i == n) + n : j = n
}
document.title = (n + 1) + ': ' + document.title;
function kdn(e, x) {
if(k > 1 && ((x = e % 63) == 37 || x == 39)) {
document.images[0].src = r + (x = s[n = (n + x - 38 + k) % k].substr(s[n].indexOf("*") + 1));
e = 12;
document.title = (n + 1) + ': ' + x;
setTimeout("status+=''", 150)
};
if(e == 12 || e == 101 || e == 107 || e == 109) {
document.images[0].style.zoom = (z = e < 107 ? 100 : e == 107 ? z * 1.2 : z / 1.2) + '%'
}
}
self.focus()
It sets the page background to black,
recovers the path-and-filename into f (with the problematical backslashes converted to forward slashes),
sets up table code so the image appears in the center of the window,
accesses the filesystemobject, and, with the path portion extracted from f into r,
sets the page title to just the filename (with the lowercase name stored to b),
and iterates the folder, checking for any image file,
creates an array s of all those files, with names in lowercase followed by their original case-format,
sorts the array case-blind, and binary-searches the array for the original file (as b) so it knows where to proceed from,
and prefixes the number-within-folder to the page title;
then the keydown function uses the left and right arrows to move backward and forward in the folder, with wraparound,
and uses the numpad+ and - to enlarge or shrink the image, and numpad-5 to reset the size (which also occurs for every new image).
It still remains, though, that I'd like to know of a way to simply pass the original %1 info to an HTML file, without writing a file in the process. I might expect it to be a way to have it "appended to the web address", as is done with info following a ? which gets placed in location.search. I don't know if the command line for iexplore.exe could have a parameter for passing info to location.search.
def listc(favn):
num = 0
while num < favn :
num += 1
return num
list = []
i = int(raw_input("Input your favourite number : > "))
for num in range(0,i):
list.append(listc(i))
print list
The elements of the list are just same. Little iterations in code are sometime printing [None] in list also.
I want to generate a list with content as 1 to i.
There are two issues with your code.
First the while loop does not run 'favn' no. of times because the return statement is within while loop.It just runs single time, and everytime it returns 1.
Also, you should change
for num in range(0,i):
list.append(listc(i))
to
for num in range(0,i):
list.append(listc(num))
You will get the output you wanted.
If you want to generate a list from 1 to i, you can simply do list = range(1, i + 1).
I answered my own question, sorry!
I started with this:
If Request("currentPage") <> "" AND isNumeric(Request("currentPage")) Then
currentPage = Request("currentPage")
Else
currentPage = 1
End If
And then on my paging links, I added:
.asp?currentPage="¤tPage+1&"
///////////////////////////////////////////////////////////////////
I have upgraded my search script to use LIMIT paging.
I am simply trying to work out what the current page is, based on the 'offset' value but I'm having some amateur troubles.
This is what I have:
currentPage = pageRange / rpp
' page range is the offset value for the LIMIT clause, for example 0, 20, 40...
' rpp is results per page value, for example 20...
If cInt(currentPage) <= 0 Then
currentPage = 1
End If
But page 1 and 2 both show "page 1", page 3 shows "page 2", page 4 shows "page 3" and so on. Obviously there is something wrong with this calculation but I cannot see it.
Any ideas?
May be better to keep track on page num and evaluate offset from it, than tracking offset? Or at least evaluate currentPage as cInt(pageRange / rpp)+1
