Is there a Function like ValueWhen for MultiCharts in EasyLanguage?

November 24th, 2016, 06:55 AM

Have to translate a code from AmiBroker AFL to easylanguage. need a function which works like the ValueWhen function of AFL. Searched in the reserved words book by MC, tried using IFF function but still not able to achieve it.

the code is:

avn=ValueWhen(avd!=0,avd,1);

somebody please help.

milkysahai001,

you can likely accomplish the same with the IFF function. What code did you try for it?
Otherwise you can either code your own function using "if... else.." statements or use them directly in the indicator
code.

ABCTG,

here, I am putting both the codes.

1. afl code:
avd=IIf(C>Ref(res,-1), 1, IIf(C<Ref(sup,-1), -1, 0));
avn=ValueWhen(avd!=0,avd,1);

2. easylanguage version: I tried getting to it with IFF function:
value1 = Iff (C < sup[1], -1, 0);
Avd = Iff (C > res[1], 1, value1);
Avn = Iff (Avd[0] <> 0, Avd, 0);

but the results are coming different from the codes.

milkysahai001,

you would have to post compileable code at least, that demonstrates the problem. With the code you posted one could only guess.
A description of what your code does and what you want it to do might be helpful, too (with a screenshot for example).

From the way you wrote the code I would guess that you misunderstand how the "ValueWhen" reserved word works and I would suggest to re-read the documentation. Think about what "ValueWhen" will return if avd = 0.

zero? i guess.

milkysahai001,

please post the link to the description where it states that.

Judging by this link https://www.amibroker.com/guide/afl/valuewhen.html
you will need to find out what the n-th most recent occurrence exactly means here.

It sounds like

Code

avn=ValueWhen(avd!=0,avd,0);

would be the most recent one, but does this mean

Code

avn=ValueWhen(avd!=0,avd,1);

is from one bar ago or is it actually the prior occurrence before the last one, which could be X bars ago.

I don't work with AFL and can't say for sure unfortunately.

The first case would be simple, but the second one might require a bit more programming as you'd have to find the
prior occurrence first.

ABCTG,

I have the same confusion about the nth most recent bar. i will dig more. Thanks for your inputs.

ABCTG,

Please find the attached images. one is the right signals in Amibroker the other is wrong-ish Indicator in Multicharts where i am not able to get signals.
