switch (Step)

[dloomis]

Anyone know of any good examples showing the use of the

switch (Step)

function?

I have seen one at

http://www.dynaorder.com/esExamples/doFollowPL.asp

and I wrote this one

http://share.esignal.com/download.js...witchDemo1.efs

to color the bars based on the close above a ma but I still don't quite get the idea

David:

It's just an alternative to if/then loops... makes the code a little easier to manage and read.

var DayOfWeek;

DayOfWeek = retrieveDay();

switch( DayOfWeek ) {
case 1: doSundayTask(); break;
case 2: doMondayTask(); break;
case 3: doTuesdayTask(); break;
case 4: doWednesdayTask(); break;
default: doSomeOtherTask(); break;
}

thanks Chris, I am getting the hang of it now...

var Step = 0;

function preMain()
{ setStudyTitle("SwitchDemo2");
debugClear();
setPriceStudy(true);
}

function main()
{ if (getCurrentBarIndex()==0)
{
switch(Step)
{
case 0:
setPriceBarColor(Color.yellow);
debugPrintln("case "+Step+": yellow bars");
Step++;
break;

case 1:
setPriceBarColor(Color.lime);
debugPrintln("case "+Step+": lime bars");
Step++;
break;

case 2:
setPriceBarColor(Color.red);
debugPrintln("case "+Step+": red bars");
Step=0;
break;
}
}
}
