VSA Indicator - Beta

[Ralph]

Do you mean TickSize?
Perhaps you could show an example?

Yes, that's what I ment. In case your final calculation can be used as integer values then it is an easy desicion. If you have to covert double-> int first and at the end int -> double then it depends (conversion takes time, integer calculation saves time).

At the example below I calculated rectangles based on prices to be plotted with the indicator's Plot()-method. Therefore the coversion made sense.

Cast

V Interesting thank you.
Is this a form of casting then - taking a double and making it an int as such?
I wonder which is quicker?

Compare( Low[0],Close[0])

or

iclose = Close[0] / TickSize;
iLow = Low[0] / tickSize;
if (iclose = ilow).....

[Ralph]

Yes, dividing with TickSize eliminates the fraction of the value, but it is still a double, the C#-compiler is very strict so you need to cast it explicitely.

I don't know which one is quicker. It is 3 operations against a single compare ...
But you could try to find it out. You could measure cpu-time in ticks (100 nano seconds) and calculate the difference.

int time1 = DateTime.Now.Ticks;
compare()...
int diff = DateTime.Now.Ticks - time1;

Ralph

[roonius]

May be it will be worth attention.
Be careful with "casting"
double doublevalue = 1.99999999;
int castValue = (int)doublevalue;

castValue gonna be 1 (not 2)

[Ralph]

Thanks roonius good point. I never had a problem with that but was wondering whether it could or should. Maybe it works because I convert before I apply the first operation to the price value. Just my personal experience.

For NT there is a function Round2TickSize() available, perhaps that's the save way.

Here is my take on the same AmiBroker code.

Notes: I coded a Wilder MA indicator that is included in the attached file. I also used LinRegSlopSFX to find the slope. Also, I used a slightly different color scheme to paint the bars with.

Hi scjohn

I am interested in this indicator ...do you have any information as to exactly what the different symbols signify. I had a look at the blogsite but it is not specific. And if I wanted to change the color code how would I? Do I need to go directly into the script?

thanks for your work!

[scjohn]

There is really no documentation of what the various symbols mean. One would have to study the code and make an educated guess.

If you want to change colors then you have to into the code and make the change.

[eDanny]

The first thing I did was change the candles since I hate solid candles and prefer to see the trend style. Also the light colors were hard to see unless the chart background was VERY dark. Even these colors work best on a darker gray background.

how to import formula

could you put it in zip format for direct importing in NT. I dont know how to import formula you rightet

Thanks in advance

[eDanny]

My version of the indicator has been edited for my own use. You will have to just copy and paste the code to your indicator. Then re-compile.

[shadTrader]

nice work, thx for sharing

can you give me a discription of how to read/use the indicator?

thx

Turn some features off

Hi,

Is there an easy way to turn some features off. Like bar coloring?

Also is there a key to what the shapes indicate

regards,

Blair

Blair,


The original author has a blog in the following http - www.vpanalysis.blogspot.com/, in order to turn off any feature just comment the associated part with " // " prior to any statement and your ready to rock.

Best Regards,

[LuboLabo]

Thanks

Thanks PrTester for your great work!!
Thanks to the others for their contribuition!

I have a question/suggestion, PrTester it's possible to change the banner and put them as background, so it does not cover the candle chart, and maybe even the possibility to change their position between the different chart corner?


Thanks.

Hey LuboLabo, only need to change the DrawtextFixed colors for Transparent and your done, also you can change the position in the same line.
