Hello Everyone,

I want to use the following filter, but when it's run, the "undefined" error shows up for the last line, can anyone help me to see how to make it work?
======Begin=====
set{YS1, 0.25 times high+0.25 times low+0.5 times close}
set{RK3,EMA(YS1,10)}
set{RK4,cstddev(YS1,10)}
set{RK51,100 / RK4}
set{RK52,YS1-RK3 }
set{RK5,RK51 * RK52}
set{RK6,EMA(RK5,5)}
set{RK7,EMA(RK6,10)}
set{zhan,EMA(RK6,10)+100/2-5}
set{xdie,EMA(zhan,4)}

show stocks where zhan crossed above xdie
=====End=========
Thank you!

You must breakup the multiple items in your SET statements.
StockFetcher allows one "thing" per SET...

For example... Here you are asking for more than one calculation and StockFetcher doesn't understand.

set{YS1, 0.25 times high+0.25 times low+0.5 times close}

Thank you for the advice, four! I changed to the following, but still not able to get the result, can you see what the problem is now?
===============================
set{YS11, 0.25 * high}
set{YS12, 0.25 * low}
set{YS13, 0.5 * close}
set{YS1_1, YS11 + YS12}
set{YS1, YS1_1 + YS13}

set{RK3,EMA(YS1,10)}
set{RK4,cstddev(YS1,10)}
set{RK51,100 / RK4}
set{RK52,YS1-RK3 }
set{RK5,RK51 * RK52}
set{RK6,EMA(RK5,5)}
set{RK7,EMA(RK6,10)}
set{zhan_1,EMA(RK6,10)}
set{zhan,zhan_1+45}
set{xdie,EMA(zhan,4)}

show stocks where zhan crossed above xdie
===============
Thank you!

Where did the calculations come from?
Do you have an example of when the cross over has occurred in the last few months or weeks?

YOU NEED THE CEMA STATEMENT TO FIND CUSTOM EMA ( set{RK6, CEMA(RK5,5)} )

set{YS12, 0.25 * low}
set{YS13, 0.5 * close}

You may need to change to the advanced plan to run this many SET statements:

Per Four, yes, I am certain the cross over happens on daily basis.

So, with graftonian's modification, you guys can see some stocks being filtered out? If so, I will consider upgrade. I currently cannot see the result, please let me know that you can see some stocks generated out of it.

Thank you!

I don't run the advanced subscription.

You could try the advanced subscription and later switch back to the regular subscription if there is no value in your filter. Check with StockFetcher.

@lkustb,

When I run Graftonian's version I get 685 stocks for the 12th and a little over 500 for the 11th.
