Is there a way to create a screener that ishows performance since 01.01?

Thanks.

Hi,

Because ProScreener has a limitation of 254 bars lookback, I coded this little indicator to compute the performance of an instrument since the first day of the year.
```
once previousbar = 0
once hh = 0
once start = close

if(barindex>previousbar) then
 previousbar=barindex
 hh=MAX(hh,high)
 var = (1-(start/hh))*100
 varmax = MAX(var,varmax)
endif

if(year<>year[1]) then
 hh = 0
 varmax = 0
 start=close
endif

RETURN varmax
```
You can include this one in your ProScreener with a CALL instruction or copy/paste the code in it and get the “varmax” variable to achieve what you want to do. Hope it helps.

Hi Nicholas.

Thanks for your help.

The indicator calculates the max year performance since start of the year.

You code is really helpfull, i use it:
```
once start = close

if(year<>year[1]) then

start=close
endif

RETURN ((close-start)/start)
```
And i have performancesincestartofyear indicator.

Then, i try to create the screener.
```
pssoy = call performancesincestartofyear
SCREENER(pssoy as "close")
```
But it doesn’t work. It gives nothing.

Can you help please?

Thanks.

Hi Andrea,

This code will solve your issue I believe, I haven’t test it:
```
once start = close

if(year<>year[1]) then

start=close
endif

perf = (close-start)/start

SCREENER [perf] (close as "close")
```

I try this but don’t work.
```
once start = close

if(year<>year[1]) then

start=close
endif

perf = (close-start)/start

SCREENER [1] (perf as "perf")
```

The screener is really screening ‘perf’ variable. But the list is populated with the actual close only.

Change the last line with this :
```
SCREENER [perf] (perf as "perf")
```

It doesn’t work!

I know why.. Because sometimes start=0 it creates a ‘division by zero’ error in ProScreener and then it stops and don’t give any results.

Here is the fixed code:
```
once start = close

if(year<>year[1]) then
 start=close
endif

if start=0 then
 start=start[1]
endif

perf=((close-start)/start)

SCREENER [1] (perf as "perf")
```

The right code is:
```
once start = close

if(year<>year[1]) then
start=close[1]
endif

if start=0 then
start=start[1]
endif

perf=((close-start)/start)*100

SCREENER [1] (perf as "performancedainizioanno")
```
Previuos code don’t calculate first day of year.

I write it if someone need it.
