preMain fuction questions ??

[buzzhorton]

preMain function questions:

1) Is it possible to have values in preMain as parameters so you can control how the study works?

Let's say you have a study that one time you want to load with pricestudy = true and then load it again with pricestudy = false.

Or one time you want to use setComputeOnClose(); but then next time you don't want it use it.


2) Should

var iDecimals = new FunctionParameter("iDecimals", FunctionParameter.NUMBER);
iDecimals.setDefault( 2 );

be coded in preMain or not?

It doesn't seem to matter but I am curious.

THANKING YOU IN ADVANCE.

The setPriceStudy() and setComputeOnClose() functions sets these study properties during the initialization process. Once a formula has been loaded on a chart you can not programmatically change these two properties through a formula parameter.

It is recommended to put FunctionParameter code inside preMain().

Hey Jason:

Looks like you are playing "catch up".

So it looks like I have to have 2 versions of a study.. one for priceStudy = true and one for = false. That just doesn't seem smart. Too bad, preMain function parameters couldn't be loaded at load time rather than hard coded.

So I guess, I will start putting the FunctionParameter code inside preMain.

Thanks again.
