Hi Empu,

Welcome to the forum.

Please have a read through the MS Users Manual and then do the exercises in the free Equis Formula Primer (see the files section of the forum to download). Armed with this knowledge you should be able to write these codes for yourself.

As always, if you get stuck writing the codes, post them here and someone will assist you to fix the problems.

Ref()


wabbit [:D]

I guess the first thing to notice is the difference between:

Ref(PVI(C),-2)

and

PVI(Ref(C,-2))

Which one are you looking for in your code?


The next thing to notice is that every time the condition specified is evaluated as TRUE, the indicator will return a value of 1. Depending on how you intend to use the indicator, you might consider only returning the first value in a succession of values, something like:

myEntryCriteria:= {expression goes here};
signals:=myEntryCriteria and alert(myEntryCriteria=0,2);
{plot}
signals;


Alternatively, if you also have a reset or exit condition defined, you can use one of the many latching systems, e.g.

buy:={expression goes here};
sell:={expression goes here};
init:=cum(isdefined(buy+sell))=1;
trade:=barssince(buy+init) < barssince(sell+init);
{plot}
trade;


For more examples on using MSFL latches search for Roy Larsen's excellent article from the files section, or use the latching function in the free forum.dll also available in the files section.



Hope this helps.
