Help with script

So im trying to do this simple script, but cant get it right:

function run ()


{

StartDate = 20120601;
EndDate = 20130120;
BarPeriod = 1440;

Stop = 50*PIP;


vars day_close = series(priceClose());
vars EMA20 = series(EMA(day_close,20));



if (day_close > EMA20)
enterLong();



I want this system to enter long when the daily bar CLOSES above EMA20. But when im checking the result-chart, this is clearly not what it does. Can anyone see what i am doing wrong here?

Thanks!

Take this as a little puzzle: What is wrong with this comparison?

if (day_close > EMA20)
...

Hmm,

My first thought is that maybe there's no differnece between day_close and EMA20 since I've typed "vars EMA20 = series(EMA(day_close,20));" before? So the computer doesn't understand what I mean. And by the looks of the result-chart... It enters a trade almost every day ^^.

Thanks jcl for helping me out.

Ok, I solve the puzzle:

You're comparing two series. What you wanted instead was comparing the two recent values of the series:

if(day_close[0] > EMA20[0])
...

Haha. Thanks jcl. I'm lucky you are here to save me all the time, so far .
Ok, I will try with the code you showed me. And i'm also going to try to plot the ma too.

Thanks once again.
