thanks, @bbhanushali & @Romeo1998

@primitivetrader : @Romeo1998 solution will give you current 30m bar's high low and my code is for previous 30m bar's high low. Use the one that suits you. Thnx. Edit: Pls check the edited code (two commented lines on "LastBar"). Thnx

str = NumToStr(nbar, 1.0) ;
PlotTextSetFont( str, "Arial", 18, i, pos+Offset, Clrtext );
PlotText(str, i, pos+Offset, Clrtext) ;

hi,
i am currently using 6.30 version. but when i insert the above code its showing the error. following is the code i am currently using can you please help me.

_SECTION_BEGIN("Bar Count");
// Author: Pratap Balakrishnan

//
// mode Text - show the barcount as a number above/below the price bars
//             every n bars as set
// mode Histogram- shows the barcount as an histogam. Best used on a different pane
//

showhisto = ParamToggle("Mode", "Text|Histogram", 0) ;
everyn = Param("Show Text Every N bars", 3, 1, 10000, 1) ;
showabove = ParamToggle("Show Pos", "Below|Above", 0) ;
Clrtext = ParamColor("Text Color", colorBlack) ;

nd = Day()!=Ref(Day(),-1) ;

nbar = 1+BarsSince(nd) ;

if (showhisto)
    Plot(nbar, "Day Bar Count", colorBlue, styleHistogram) ;
else
{
    bi = BarIndex() ;

    showtextbar = ((nbar -1) % everyn) == 0 ;
    if (showabove)
    {
        pos = H ;
        Offset = 10 ;
    }
    else
    {
        pos = L ;
        Offset = -10;
    }

    Visfirst = FirstVisibleValue(bi) ;
    Vislast = LastVisibleValue(bi) ;

    for (i = Visfirst; i <= Vislast ; i++)
    {
        if (showtextbar[i])
        {
            str = NumToStr(nbar[i], 1.0) ;
            
            PlotText(str, i, pos[i]+Offset, Clrtext) ;
        }
    }
//    PlotShapes(showtextbar*shapeSmallCircle, colorBlue, 0, H, 50) ;

}
_SECTION_END();

So now you know it can fail ..

zTickSize=0.05;
function zRoundUp(zValue) {return ceil(zValue/zTickSize)*zTickSize;}
function zRoundDown(zValue) {return floor(zValue/zTickSize)*zTickSize;}

pricex =  9744.351;
t2 = zRoundDown(pricex) ;

_N( Title = ( "" + t2 ) ) ;

Sorry about the late reply. Had not logged in for a few days, and had not seen your reply.

I am guessing that you are saying that zRoundDown() does not work in the example that you shared. I am not sure if that is what you mean. Your example code rounds down properly in my AB. I have been using that code for years now, so I would be surprised if it doesn't work.

It could be an issue with the Amibroker versions. I use AB version 5.40.3 (as outdated as me). Though I had purchased a later version of AB, I continue using the old version, mainly because it compresses range bars in a style that I prefer.

My version of AB does have other issues related to rounding off though. It does not display the hundredths place value of numbers greater than 10000 (NF and BNF). 12171.85 is displayed as either 12171.8 or 12171.9. And when I use Prec(C%10000,2) to find the hundredths place value (ignoring the first digit), it gives me either 2171.84 or 2171.85. Strange, but I am used to it now...

Hi coders.... need a help

below is a exploration code of monthly high/Low of previous month. I want to add date column for both high/low so that I can easily understand when any particular symbol made high/low in previous month.


PMH = TimeFrameGetPrice("H",inMonthly,0,expandLast);
PML = TimeFrameGetPrice("L",inMonthly,0,expandLast);
Filter = 1;
AddColumn(PMH,"P Month High");
AddColumn(PML,"P Month Low");

Seniors, I want afl scanner for a particular candlestick setup. Can any one help me with afl developing. If it involves any cost for it i am ok with it. My email is [email protected].
Regards

PlotText(str, i, pos[i]+Offset, Clrtext) ;

thanks a lot it worked well

in analysis use Daily periodicity and explore...
Left column date/time will show the last date of data present of previous month...
right columns will show date of high n low but it is in datenum format...
i tried to convert it to string, but was not successful, maybe some senior coders will be able to help...
good luck

TimeFrameSet(inMonthly);
pmh = H;
pml = L;
TimeFrameRestore();

pmh = TimeFrameExpand(pmh,inMonthly,expandFirst);
pml = TimeFrameExpand(pml,inMonthly,expandFirst);

pmh_date = ValueWhen(pmh==H  ,DateNum());
pml_date = ValueWhen(pml==l  ,DateNum());

Filter = Month()!=Ref(Month(),1);
AddColumn(PMH,"P Month High");
AddColumn(pmh_date,"PMH_date",1.0);
AddColumn(PML,"P Month Low");
AddColumn(pml_date,"PML_date",1.0);

I am attaching the chart in which the desired setup of afl is explained. Can any one provide afl code for this kind of setup.

Thanks alot for your efforts sir. I did not find any periodicity option in analysis. so when I tried to run ur code it showed nothing. only blank columns seen.
