Hi guys

I would create an indicator which show me when moving average changes direction.

For example : indicator=1 when moving average changes and going up
indicator=-1 when moving average is going down

I have written this code :

Code: Select all


Inputs: price(Close), length(10),

zeroLine(0.0), zeroVisible(false),

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



Variables: var0 (0) ;



var0 = jtHMA(price, length);



//when the average changes direction : (moving average is going down)

if var0[2] > var0[1] and var0[1] < var0 then

value2 = 1 ;



//when the average changes direction : (moving average is going up)

if var0[2] < var0[1] and var0[1] > var0 then

value2 = -1 ;



Plot1(Value2, "jtHMA");

I have posted a picture of this code here : http://www.heberger-image.fr/images/874 ... s.png.html

Anybody would have an idea please?

First thing I can suggest to you is to avoid using generic variable names,
ie. var0, value1, value2, condition1, condition2, etc.,

You can give each variable a meaningful name, eg. jtHMA.dir, avg.dir, jtHMA.up, jtHMA.dn, etc.,
In the long run, it will save you lots of debugging time.

I revised the code like this :

Code: Select all

Inputs: price(Close), length(10),

zeroLine(0.0), zeroVisible(false),

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



Variables:

average_jtJMA (0) ,

indic (0) ;





//compute mobile average

average_jtJMA = jtHMA(price, length);



//when the average changes direction : (moving average is going down)

if average_jtJMA[2] > average_jtJMA[1] and average_jtJMA[1] < average_jtJMA then

indic = 1 ;



if indic[1] = 1 then

indic = 0 ;



//when the average changes direction : (moving average is going up)

if average_jtJMA[2] < average_jtJMA[1] and average_jtJMA[1] > average_jtJMA then

indic = -1 ;



if indic[1] = -1 then

indic = 0 ;





Plot1(indic, "change_direction");

Nice work. Thanks for sharing.

Here's my rendition; it runs slightly faster.

Code: Select all

Inputs: price(Close), length(10),

zeroLine(0.0), zeroVisible(false),

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



Variables:

average_jtJMA (0) ,

indic (0) ;





//compute mobile average

average_jtJMA = jtHMA(price, length);



//when the average changes direction : (moving average is going down)

if average_jtJMA[2] > average_jtJMA[1] and average_jtJMA[1] < average_jtJMA then

indic = 1 



else



//when the average changes direction : (moving average is going up)

if average_jtJMA[2] < average_jtJMA[1] and average_jtJMA[1] > average_jtJMA then

indic = -1 



else



indic = 0 ;



Plot1(indic, "change_direction");
