Hi,
I’m looking for a screener that would return stocks for which the background color for the PRT bands just turned green over the last 3 days.
anyone would know how to code this one ?
thanks

here is one way to do it :
```
up = PRTBandsUp
dn = PRTBandsDown
 
if close crosses over up and trend<=0 then //le prix casse la bande supérieure
trend=1 //tendance haussière
elsif close crosses under dn and trend>=0 then //le prix casse la bande inférieure
trend=-1 //tendance baissière
endif

screener[(trend=1 and trend[1]=-1) or (trend=1 and trend[1]=1 and trend[2]=-1) or (trend=1 and trend[1]=1 and trend[2]=1 and trend[3]=-1)] (Average[50](Volume))
```

Hi,
I managed to get my screener working for the PRT bands, but I’m struggling with filtering on volumes.
here is the initial version :
```
up = PRTBandsUp
dn = PRTBandsDown
 
if close crosses over up and trend<=0 then //le prix casse la bande supérieure
trend=1 //tendance haussière
elsif close crosses under dn and trend>=0 then //le prix casse la bande inférieure
trend=-1 //tendance baissière
endif

screener[(trend=1 and trend[1]=-1) or (trend=1 and trend[1]=1 and trend[2]=-1) or (trend=1 and trend[1]=1 and trend[2]=1 and trend[3]=-1)] (Average[50](Volume))
```
This does the job and returns 144 results on Nasdaq.
Then I tried to add a filter on volumes to get rid of less liquid stocks by adding 2 conditions on average and lowest value:
```
up = PRTBandsUp
dn = PRTBandsDown
 
if close crosses over up and trend<=0 then //le prix casse la bande supérieure
trend=1 //tendance haussière
elsif close crosses under dn and trend>=0 then //le prix casse la bande inférieure
trend=-1 //tendance baissière
endif

// DEFAULT CONDITIONS
v1 = Average[50](Volume) >= 50
v2 = Lowest[256](Volume) >= 15
defaultConditons = v1 AND v2
// DEFAULT CONDITIONS

screener[((trend=1 and trend[1]=-1) or (trend=1 and trend[1]=1 and trend[2]=-1) or (trend=1 and trend[1]=1 and trend[2]=1 and trend[3]=-1)) and defaultConditons] (Average[50](Volume))
```
Now the screener will only return 8 results. Apple will an average of 60.2M is excluded by this filter. Makes no sense to me. What did I do wrong/misundertand ?
thanks

Hi,

C1=Summation[3](Trend=1)=2

C2=Summation[3](Trend=1)=1
Screener[C1 or C2]
If you take the last three days, it is: Trend[0], Trend[1] and Trend[2]

Hi,

When I use the “Default Conditions” in your screener, I get almost the same number of shares back as without the “Default Conditions”…

Be careful with the spelling of “Default Conditions (Conditons)”

I think you’re at the limit of your historical data usage…

How much historical data can/may you use 256 or 1024?
