Hi

Please point out exactly which one you are referring to

Thanks'

Happy

Is it possible to decode it like in this screen shot. Red and green lines are bands based on keltner channel of TEMA high and TEMA low.

2 afls
1) Keltner bands along with OBV
2) Keltner band along with price action

Thanks a lot in advance HAPPY :clapping::clapping:

Its simple, he has just dragged and dropped the indicators on to the chart

However all the indicators/params are not seen in the Title as it has less space (i.e its going beyond the screen size)
but whatever is seen in the title can be reproduced.

BTW the same trader has disclosed his method and answered to members queries on Mudra,
anyone interested can check there, use google he uses same ID there

Thanks Happy.

I have tried by drag and drop but i failed to create.All i am looking from above posted chart is

Pane1 :- 1) Along with OBV Another line TEMA(OBV,36) and KBTop(BBTop(TEMA(OBV,36)8,2),8,0.4) and KBbot(BBTop(TEMA(OBV,36)8,2),8,0.4)


Pane 2 :- Almost similar like above but I can try to mimic if you are able to help me with Pane 1 AFL

KBTop(TEMA(HIGH,8),8,0.4) and KBbot(TEMA(HIGH,8),8,0.4)

I am trying to use this along with my mixer system :lol::lol:.

Thanks a lot in advance

Drop them in the sequence they appear and then setup the parameters after pasting.

Anyway here is the code, just setup parameters . . .

For TEMA use OBV as Price Field
For BB use TEMA as Price Field
For first Ketler band use BBTop as Price Field
For second Ketler band use BBBot as Price Field

Also adjust other parameters as per your requirement

_SECTION_BEGIN("OBV");
Plot( OBV(), _DEFAULT_NAME(), ParamColor("Color", colorCycle ), ParamStyle("Style")  );
_SECTION_END();


_SECTION_BEGIN("TEMA");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1, 10 );
Plot( TEMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") ); 
_SECTION_END();

_SECTION_BEGIN("Bollinger Bands");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1 );
Width = Param("Width", 2, 0, 10, 0.05 );
Color = ParamColor("Color", colorCycle );
Style = ParamStyle("Style");
Plot( BBandTop( P, Periods, Width ), "BBTop" + _PARAM_VALUES(), Color, Style ); 
Plot( BBandBot( P, Periods, Width ), "BBBot" + _PARAM_VALUES(), Color, Style ); 
_SECTION_END();

_SECTION_BEGIN("Keltner Bands");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1 );
Width = Param("Width", 2, 0, 10, 0.05 );
Color = ParamColor("Color", colorCycle );
Style = ParamStyle("Style", styleLine | styleNoLabel);

CenterLine = MA( P, Periods );
KTop = CenterLine + Width * ATR( Periods );
KBot = CenterLine - Width * ATR( Periods );

Plot( KTop, "KBTop" + _PARAM_VALUES(), Color, Style ); 
Plot( KBot, "KBBot" + _PARAM_VALUES(), Color, Style ); 
_SECTION_END();


_SECTION_BEGIN("Keltner Bands1");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1 );
Width = Param("Width", 2, 0, 10, 0.05 );
Color = ParamColor("Color", colorCycle );
Style = ParamStyle("Style", styleLine | styleNoLabel);

CenterLine = MA( P, Periods );
KTop = CenterLine + Width * ATR( Periods );
KBot = CenterLine - Width * ATR( Periods );

Plot( KTop, "KBTop" + _PARAM_VALUES(), Color, Style ); 
Plot( KBot, "KBBot" + _PARAM_VALUES(), Color, Style ); 
_SECTION_END();

BTW, i don't even think this was done intentionally, :lol:
that's the way AB works when we drag n drop new indi's on the chart
taking the previous indicator as input for next one

anyway no harm in experimenting . . . . :thumb:

Hi again

Instead of using such a clutter of superimposed indicators, we can simply modify
the OBV or any other line / wiggle type indicator to be plotted at a Histogram . . .

_SECTION_BEGIN("On Balance Volume");
Ob		=	OBV();	
eOb 	=	EMA(Ob,34);
delta	=	Ob - eOb;  			//Difference in Ob & its EMA
ObCol	=	IIf(eOb > Ref(eOb,-1),ColorRGB(60,60,180),ColorRGB(180,20,20)); 

Plot(delta,"Delta",ObCol,styleThick|styleHistogram);
Plot(delta,"",ObCol,styleNoLabel);
Plot(0, "", ObCol,styleNoLabel|styleThick);
_SECTION_END();

Cheers

Hi, No offence, but..

can any one explain the purpose of comparing ema with prev ema ? (code underlined )
Why ob and prev ob is not compared ?

Hi, No offence, but..

Why ob and prev ob is not compared ?

In case of OBV, every green bar it increases and every red bar it decreases
so just looking at candle you will know if its increasing or not
no need to compare

EMA (or any other average) is used for smoothening the original data series
Comparing tells us if it is rising or falling (choice of period is important)

One interesting fact about OBV is that
in this particular case eOb > Ref(eOb,-1) is same as Ob > eOb
i.e cross of indicator above/below the moving average . . . .

Think about it, is it always so ? why ??

Happy Ji,

I am trying to write my First AFL for opening Range breakout.
Getting some issues here. I can get code from web easily, but want to write it on my own to learn it.

Here is the issue I am facing:

I am using 1 Min Chart for last 30 days.
To find out High of first 15 min, I am using this code:

tn = TimeNum();

ObservationStartTime = 91559;
ObservationEndtime = 92959;

StartBar = tn == ObservationStartTime;
EndBar = tn == ObservationEndtime;

OpeningHourHigh = ValueWhen( EndBar, HighestSince( StartBar, High ) );
OpeningHourLow = ValueWhen( EndBar, LowestSince( StartBar, Low ) );

OpenHourRangeValue = OpeningHourHigh - OpeningHourLow;

Issues:
1. On Day 2, from time 09:15 to 09:30, the chart displays previous day's Opening Hour High Low values. I want it to be reset on Market close. I tried various options last night. But nothing fruitful so far.
2. OpeningHourHigh, OpeningHourLow, OpenHourRangeValue - all these values are of Array Type. I don't get it. Why are they of Array Type? They should be of numeric type because I am finding High of few bars and Low of few bars. Then subtracting those.

If I do Lowest(OpeningHourLow), on day 4, it returns me Low of last 4 days lowest value in opening hours, which is not good. I believe even if I am assigning it with '=', Ami is pushing that new value in that array.

Can I explicitly declare these variables to be of number type and not to push new values, but only to remember newest value?

Kindly let me know what I am doing wrong here? Any guidelines / links to learn will be appreciated. I am a programmer by profession. So, I believe I can pick it up quickly, but currently need to know why these functions return types are arrays and not only the number.

Thanks

Hi Tarun

Many versions of ORB are already shared even on traderji, please search you will find the AFL,
one of the version is shared by our Angubai, he has traded it extensively and also share his experience with it.
