AB = Plot StyleCloud on MA Ribbon

[aaa 10]

I've adapted MA Ribbon from EL 2 AB

How 2 plot a cloud between the 2 avgs and change color area when avg crosses ??

 

Here is my preliminary code

 

Plot(C,"Price",colorBlack,styleCandle);

Periods      = Param("Periods",      30, 2, 200, 1, 0 );
Displacement = Param("Displacement", 30, -150, 150 );

Plot( EMA( c, Periods ), "", 
ParamColor( "ColorMM", colorBlue ), 
ParamStyle( "StyleMM") | styleThick | styleNoRescale ); 

Plot( EMA( c, Periods ), "" , 
ParamColor( "Color Delay", colorWhite ), 
ParamStyle( "Style Delay") | styleNoRescale | styleNoLabel, Null, Null, Displacement  );

 

I've found this from ICHIMOKU

 

The problem is where 2 put Displacement ?

 

PlotOHLC(Span1,Span1,Span2,Span2,"Cloud",colorWhite ,styleCloud );

Hi Tams

 

I shouls have precised that it's a snapshot from the Xcellent help...

 

It was 2 illustrate the ICHIMOKU stylecloud which is similar than your MA Ribbon

 

PlotOHLC(Span1,Span1,Span 2,Span2,"Cloud",colorWhit e ,styleCloud );

 

Oups....

[Head2k 10]

Use Ref function for displacement.

 

Plot( Ref( EMA( c, Periods ), Displacement), ...

 

Negative displacement moves the average in the past, positive displacement in the future.

 

Anyway, the whole code would be as follows:

 

Plot(C,"Price",colorBlack,styleCandle);

Periods      = Param("Periods",      30, 2, 200, 1 );
Displacement = Param("Displacement", 15, 0, 150, 1 );

EMAactual = EMA( c, Periods );
EMAdisp = Ref( EMA( c, Periods ), -Displacement);

Color = IIf( EMAactual > EMAdisp, colorGreen, colorRed);

PlotOHLC( EMAdisp , EMAactual, EMAdisp, EMAactual, "Cloud", Color, styleCloud);

 

that's a nice looking chart...

I admire people who can trade off flying carpets.

[Head2k 10]

Negative displacement moves the average in the past, positive displacement in the future.

Sorry, actually it is the other way around. Negative displacement moves the past data into the future and positive displacement moves the future data into the past.

So with positive displacement you refer to future data which are not known in the actual moment, and that won't work in real time usage and it can screw up your back test.

 

That's why I allowed only for negative displacement in the code.

Hi Head2K

 

ThanX again 4 your help

 

Ref( formula ); is the key of the magic carpet 2 make it flying

 

Now 3 questions for a champion :haha:

------------------------------------------------

 

about else

 

ColorBuble =

IIf( Condition1, Color1,

IIf( Condition2, Color2,

IIf( Condition3, Color3,

IIf( Condition4, Color4,

ElseColor )))) ;

 

For each condition we must add a ) at the end

In this case I don't need the elseColor

 

But it works fine

 

Is there an other smartest way ?

 

------------------------------------------------

 

 

Negative displacement moves the average in the past, positive displacement in the future.

 

I've seen that the colors is 1 bar late than normally

 

How 2 avoid that ?

 

----------------------------------------------------------------------

 

I don't arrive to change the color of an avg when it changes trend

 

EL

 

if avg > avg[1] then

SetPlotColor[1](1, Line.upcolor);

else

SetPlotColor[1](1, Line.dncolor);

 

AFL

 

IIf( EMAactual < EMAactual[1] , colorYellow, colorBlue);

 

The problem is the [1] I think

[aaa 10]

I'm surprised to arrive to transpose "easily" code from EasyLanguage 2 AFL

 

I thought C is complicate but, for easy indicators I use, it is OK

 

May B AFL is the "EasyCLanguage" ?

To the 1st question:

If you want the color to change in a discrete manner you can list the conditions just like you did.

If you want the color change continuously over the color spectrum, or if you can join your descrete conditions into a mathematical function, then you can use this function to define the color.

Then you can use ColorRGB function (find it in AFL help) to change the color. So you need to convert your conditions into mathematical functions which output values between 0 and 255 for red, green and blue.

 

To the 2nd question:

The color change doesn't happen late. If you zoom in you can see that the two averages cross usually somewhere in between of two bars. The color is defined by relation of the two averages at the last bar. Then the averages cross, but before the next bar is reached the color remains the same. Once the next bar is reached, the relation between the averages is re-examined and the color changes at that bar.

AmiBroker can't change color somewhere between bars, only at a bar.

 

To the 3rd question

IIf( EMAactual < EMAactual[1] , colorYellow, colorBlue);

This will always return colorBlue, because you compare EMAactual to EMAactual, that is two same numbers. So the expression in the condition is always false.

I can't judge this. I am not a programmer and I never learned C. I've learned just AFL from AmiBroker help.

When I was a 10 years old child I used to learn TurboPascal which was kind of an educational programing language, so I had an idea about what a loop is and so on. So the only thing I can say is that AFL is probably easy, because if one has some elementary knowledge of programing languages principles, then he/she can learn it very well only from the help included in AB.

It's a gift that they are people like U always ready 2 light up the darkness of our minds

 

I'm mad at me that I always badly exposed my questions even tho I thought it was clear

 

So I will now separate ALL questions with Code + graph

[aaa 10]

I've seen that the colors is 1 bar late than normally

 

How 2 avoid that ?

 

I've coded in AFL a special indicator 2 show U where is the problem

 

I"ve also coded in EL EXACTLY the same indicator and the colors matches perfectly

Dear James

 

Should it B possible 2 add

FileType in the attachment key ?

My supposition

 

If no condition is filled then result = 0

 

else = 0

 

Korrect ?

Dear Head2K I agree with U

 

Here is my personnal Xperience and that's strange it matches yours

 

Strange... did I say Strange ? It's strange...

 

When I was... 18 month ago B4 I used 2 learn EL which was kind of an educational programing language from TradersLaboratory

 

so I had an idea about what a loop is and so on. :bang head:

 

So the only thing I can say is that EL is probably easy, :question:

 

because if one has some elementary knowledge of programing languages principles, :smoking:

 

then he/she can learn it very well only from the help included in TradersLaboratory :cheers:

Kind regards

Well, to enlighten you a bit more, knowing how to program isn't the same as knowing how to trade. To take it even further, knowing how to program a "flying carpet" is good only for realizing that a flying carpet is useless.

I am not sure what a trader you are and what your experience is, but I think that time for programing comes, if ever, only when you thoroughly understand price action and you want to (partially) automate your discretionary strategy. But to start a trading career with flying carpets and EMA coulds is a mistake. Everything IMHO, of course.

If you want me to compare two indicators, then you should use them on the same chart. I don't know what you mean exactly.

 

I see that in the AmiBroker indicator you obviously use two plot functions. One with styleArea and another with styleCloud. StyleArea is a widened histogram, so the colored columns have middle at the middle (vertical axis) of a bar. StyleCloud changes color at the middle of a bar. That's why the the color changes are shifted by a half of the inter-bar spacing.

If you mean something else then specify it better and use the same chart for muticharts and AB indicator.

 

_____________________________

 

IIf( EMAactual < Ref( EMAactual, -1) , colorYellow, colorBlue);

 

______________________________

 

ColorBuble =

IIf( Condition1, Color1,

IIf( Condition2, Color2,

IIf( Condition3, Color3,

IIf( Condition4, Color4,

0 )))) ;

 

Here, if no condition is met then ColorBubble will be zero.

Thanx 4 your clever advice

 

Everybody should B aware of the frontier beetween the dream pretty game colored software indicators

 

and the black & white reality of market

 

where they are imo 3 mainly indicators

 

UpTrend

 

DownTrend

 

Range

 

----------------------

 

How do I trade ?

 

With a magic lampe!!!

 

Seriously

 

Like everybody

 

I try 2 buy when the price is low and I sell when the price is high

 

The opposite in downtrend

 

I hold a position from a few minutes to a complete swing trade only in daytrading on Estoxx future

 

I don't use any traditional indicator but a simple home made system based on price observation

 

I've noticied that studying programming is an Xcellent way 2 learn

 

But 2 learn what ?

 

I don't know exactly how 2 explain that , may B logical, concentration ,conditions, eventuality, resolving, perseverance, humility, etc... like with a chess game, like with a chart (?)

 

the only thing I'm sure that I have 2 learn for understand things arround me.

 

And the more I learn indicators, the more I think that they are not (4 me, always imo) the only (best ?) way

 

There is an alternative 2 find which can make the difference beetween trading and a Be a Trader

 

I spend a huge time just 2 observe "naked" price 2 communicate througt mind with the other people behind them

 

It's an egyptian language and I don't have (yet) the rosette stone 2 help me

 

I think that Trading is a personnal instrospection and each one must find his own way with their own instruments

 

I am not married with Multicharts and AmiBroker could B an other interesting alternative platform

 

My questions here are 2 learn , not 2 trade flying carpets with a magic lamp !!!

 

And I appreciate a lot your straight honesty.

 

regards
