intern hlc3 function 5 times faster than own

[franzmey]

hi,

why is

function main()
{
 return hlc3();
} 

5 times faster than my own function?

function main()
{
 return myhlc3();
}

function myhlc3()
{
    return (high() + low() + close())/3;
} 

How can I speed up my own functions like above example?

Use the values instead of the series [ie high(0) instead of high()] to perform the calculations in the function

Alex,

thank you very very much for your posting!
The EFS Performance Monitor loves it.


I unterstand now, that high() is a series, because of an internal eSignal-study, but why is myhlc3() not a series, if I call it in the same way like the high()?

myhlc3() is a call to a function which returns the result of a calculation and not a series object.
If you want to create a series of that return then you would need to use efsInternal() to call the function. For example var myVar = efsInternal("myhlc3");

Ok, I thought only, because it worked with an example of my tests today...

With next code, I get a series:

function main()
{
    return sma(14, abc());
}

function abc()
{
    return close();
} 

and with next code not.

function main()
{
    return sma(14, abc());
}

function abc()
{
    return close(0);
}

That is because in the first example the function is returning a series whereas in the second it is returning a value.
Keep in mind that when you process a series ie you do (high()+low())/2 the result is not a series but a value.
