Plot Statement Issue

[PeterBrazel 10]

I have constructed the following code that I want to plot only on a direction chane in the average:

 

If PlotSlow=True and Displace >= 0 or CurrentBar > AbsValue( Displace ) then

begin

If Value2[2]<=Value2[1] and Value2>=Value2[1] then

Plot6(Low-Offset,"Up") else

if Value2[2]>Value2[1] and (Value2 < Value2[1]) then

Plot7(High+Offset,"Dn") else

NoPlot(6);

 

I only want a single plot when the condition is true but I get plots most of the time.

 

Where am I wrong here. Cannot see the forest for the trees sort of question.

[Tams 20]

the following can be interpreted multiple ways:

 

If PlotSlow=True and Displace >= 0 or CurrentBar > AbsValue( Displace ) then

 

 

suggestion:

use brackets to isolate multiple/complex Boolean logics.

Special thanks for all the assistance you have given me over various posts Tams. Whilst my programming skills are very weak you have assisted me to struggle through several issues such that I have ultimately achieved my original objective with several indicators.

 

My current issue relates an adaption of the jtHMA to have showme's plotted only when the the MA changes from up to down and vice versa.

 

This code:

 

"Displace >= 0 or CurrentBar > AbsValue( Displace ) then "

 

was lifted directly from the jtHMA code. Commenting it out does not seem to change my output result one way or other, that I can see.

 

I am getting plots above and below each bar rather than just on the bar where the MA changes from up to down and vice versa.

 

I have attached a screenshot of my code and the output.

Sorry...here is the attachment

If PlotSlow=True and Displace >= 0 or CurrentBar > AbsValue( Displace ) then

begin

 

If Value2[2]<=Value2[1] and Value2>=Value2[1] then

Plot6(Low-Offset,"Up") {<--- this plots below}

 

else

if Value2[2]>Value2[1] and (Value2 < Value2[1]) then

Plot7(High+Offset,"Dn") {<--- this plots above}

 

else

NoPlot(6);

try this:

 

 

If PlotSlow=True and Displace >= 0 or CurrentBar > AbsValue( Displace ) then

begin

If (Value2[2]<=Value2[1] and Value2>=Value2[1] )

or

(Value2[2]>Value2[1] and (Value2 < Value2[1])) then

Plot7(High+Offset,"Dn") else

NoPlot(6);

Thanks once again.

I copied your code but the result is unchanged.

[Tams 20]

did you copy the whole thing in post #6?

 

can you draw a mock up to illustrate how you want it plot?

[PeterBrazel 10]

Yes I cut and pasted the code as in post 6.

 

Attached is a screen capture of a chart. Ignore the larger time frame multi coloured MA and have a look at the jtHMA which is the red and blue coloured MA.

 

I have marked up and down arrows at the location at which the jtHMA changes colour. This is all the information I need on my chart. The yellow dots represent the output using the code as per your post 6.

 

This code appears very straight forward but something is causing these multiple plots.

 

Thanks

[Tams 20]

I don't understand what do you need.

[PeterBrazel 10]

!!!!Yes I did

Refer to the Blue/Red HMA.

Yellow dots are what our code produces.

Arrows is where I want the dots to plot.

[PeterBrazel 10]

I do not want to plot the jtHMA as a line on my chart. I want to plot only a single dot above the bar where the MA turns down and a single dot below the bar where the MA turns up. This is the only information that I need from this indicator.

[Tams 20]

can you post the code of your jtHMA ?

there are different versions floating around on the web. I don't know which one you are using.

{jtHMA - Hull Moving Average Indicator}

{Author: Atavachron}

{May 2005}

 

{

Inputs:

-------

price: the time series being smoothed, usually Close, High, etc,

but could be RSI(Close, 25) for example.

length: the length of the MA, pretty meaningless in the normal sense

of moving averages, as this quantity is heavily modified

in the code. You need to experiment, do not just use a setting

of 20 because that is what works for you with Simple Moving Averages.

zeroLine: if you are using this in an indicator pane, you might

want to display a centre line of some sort, ths allows

one to set its value

zeroVisible: boolean variable, determines whether the centre line

(zeroLine) is plotted.

upColour: If you wish to differentiate upward movements by colour coding.

downColour: If you wish to differentiate downward movements by colour coding.

colourDeltaBar: Set this to 1 if you wish the colour change to be effective on

the actual bar where the direction change occurred.

Set this to 0 for default behaviour. All other values

are pretty meaningless.

}

 

Inputs: price(Close), length(21),

zeroLine(0.0), zeroVisible(false),

upColour(Blue), downColour(Red), colourDeltaBar(1);

 

Value1 = jtHMA(price, length);

 

Plot1(Value1, "jtHMA");

 

If ZeroVisible = true then

Plot2(zeroLine, "Zero");

 

{ Color criteria }

if (Value1 > Value1[1]) then

SetPlotColor[colourDeltaBar](1, upColour)

else if (Value1 < Value1[1]) then

SetPlotColor[colourDeltaBar](1, downColour);

PeterBrazel,

 

In your code you need a condition to check if previous bar has the same criteria, then do not Plot.

 

Here is the code plotted as ShowMe.

 

Regards,

Suri

 

 

================

vars:

PlotSlow(TRUE), Displace(0), Offset(0.5), Length(21), Trigger(0);

 

 

if (BarStatus(1)=2) then

begin

 

If (PlotSlow=True and (Displace >= 0 or CurrentBar > AbsValue( Displace))) then

begin

Value2 = jtHMA(Close, Length);

If (Value2[2]<=Value2[1]) and (Value2>=Value2[1]) then

Trigger = -1

else if (Value2[2]>Value2[1]) and (Value2 < Value2[1]) then

Trigger = 1

else Trigger = 0;

 

if (Trigger <> 0 and (Trigger <> Trigger[1])) then

begin

if (Trigger = -1) then

Plot6(Low-Offset,"Up") {<--- this plots below}

else if (Trigger =1) then

Plot7(High+Offset,"Dn"); {<--- this plots above}

end;

end;

end;

Suri,

 

Thank you very much.

 

I will try to work out why this is so and try to get an understanding of your solution to this issue. As you can see I am not much of a codey. In the meantime this result is exactly what I set out to achieve.

 

All the assistance on this forum is first rate and appreciated.
