Translating EMA-values to ZN-values or visaversa

June 15th, 2009, 12:02 PM

hi all,
ZN is seems to get trendy here in this area ;-)
but i realized that is has strange values and cant be used together with MAs in a strategy because of this. EMA values + ZN values are totaly different- ie. if you wanna code an ENTRY after the Bar closes Above / Below EMA 50 - thats not possible at the moment. i am looking looking for some ideas to manage this, maybe someone got a "translation-code" in his pocket yet ;-)
Thanks for infos

hi max,

what are ZN-values. I do not know. but i think mike has same problem.

perhaps 123'234 anstead 123.57578 then i can give method ...

best regards

This code may be of use, it was provided by Roonius:

private string FormatZN(double price)
{
return String.Format("{0}'{1:000}", Math.Truncate(price), (price - Math.Truncate(price)) * 320);
}

The number "320" is the bond fraction or number of pips per point. ZN is 320.

private string whatisthat(double number)
{

//string s = "114.843750";

string s = Convert.ToString(number);
string[] numbers = s.split('.');

string zahler = "";
double dnenner = 0;

for(int i = 0; i < numbers.length; i++)
{
if(i == 0)
String zahler = numbers[i];

if(i == 1)
String tmp = numbers[i];

double dtmp = Double.Parse(tmp);
dnenner = dtmp/ 320;
}

string nenner = Convert.ToString(dnenner);

string val = zahler+"'"+nenner;

return val;
}

is not tested some bugs inside

hi - one more try - with your codeexamples i couldnt do anything - i am just a copy+paste coder.
But i know what i need
here is an example of my condition-idea - very simple stuff :

double ZNvalueclose = Close[0] ;
double ema33 = EMA (33) [0] ;

if ( ZNvalueclose < ema33 )

{ go short }

But now we konw the problem that ZN gives us (europeans espcialy

) some grazy numbers wich are not comparable with the EMA-values.

so i need a bit of math-magic to translate my ZNvalueclose into a normal valuedouble

double ZNvalueclose = Close[0] ;

double ZNvalueNORM = ZNvalueclose * magic-maths ;

double ema33 = EMA (33) [0] ;

if ( ZNvalueNORM < ema33 )

{ go short }

i always work with such doubles only - need no dataseries or other big things
please dont laugh - thats the way i code my things + it works + thats my goal

maybe someone got an idea

i saw this Math.Truncate-Method in mike psoting - but dont know what tish is / how to use it in my formular

ok -another step DONE !

protected override void OnBarUpdate()
{

double EMAprice = EMA(30)[0];

string emaTOznvalue = String.Format("{0}'{1:000}", Math.Truncate(EMAprice), (EMAprice - Math.Truncate(EMAprice)) * 320);

emaTOznvalue now gives out the EMA in ZN-format
ie like : 114�025

next step is converting this string to a double to be able to use it for conditions in indicators or strategys in combination with PA (price-action)
stay tuned ...

Nice work max!

you need a string format, that can you parse to a double.
or you use the replace function in c# and then do parsing ...

string s = "114�025";

string v = s.Replace("�", ".");

double z = Convert.ToDouble(v);

You need a dot that you get a good double value ...

Thats what i have - a propper sting with this ` - thing.
You see the output in the text-box.

oh - you think i have to replace that " ` " + make it a dot !?
