Hello

To discuss about the screener

https://www.prorealcode.com/prorealtime-market-screeners/startup-all-time-low-obvolume-weinstein-wyckoff/

The idea is to find a startup bottom by screening volume activity.

Even with this code modification, sometime the condition
```
//ATL All time low identification
ATL = lowest[BarIndex](low) 
//for i = 1 to barindex
 
// If low[i]<ATL or ATL=0 then
//  ATL=Low
// else
//  ATL=ATL[1]
// Endif
//Next

//High volume activity
myOBV = OBV(close)
avgOBV=average[20](myOBV)
stdevOBV=2*std[20](myOBV)
BollUp = avgOBV+stdevOBV
 
 
//ATL zone and volume activity
c1=close<2*ATL
c2=myOBV>BollUP
 
screener[ c1 and c2 ]
```

Basically

The idea is coming from this lecture from Wyckoff, Weinstein

It is best to talk about screeners in the screener forum. 🙂

Topic moved from ‘General Discussion’ forum.

Firstly, try this small modification to be sure ProScreener isn’t stopping on the first barindex:
```
//ATL All time low identification
ATL = lowest[max(1,BarIndex)](low) 

//High volume activity
myOBV = OBV(close)
avgOBV=average[20](myOBV)
stdevOBV=2*std[20](myOBV)
BollUp = avgOBV+stdevOBV
 
 
//ATL zone and volume activity
c1=close<2*ATL
c2=myOBV>BollUP
 
screener[ c1 and c2 ]
```

Hello,
The idea that I applied to evaluate the actions is based on the application of a macd to the Obv, with a configuration (10,20,10), and on the obv macd I apply some bolliguer bands. In this way the possible changes are very well detected.

Is there a minimum time period to consider an accumulation phase as valid?

Hi JJ Tec could you share a graph , that I can see and understand your point?

Hi @Nicolas

There is no minimum of time period, it can be very fast or very slow.

For the code modication, this test give the same result , the problem doesn’t come from the BarIndex
```
//ATL All time low identification
ATL = lowest[max(1,BarIndex)](low) 
```

I’d like to help but your first post is truncated, so I still don’t know what is the problem? 🙂

The idea I have is to apply the Chaikin flow calculation formula, to the OBV, but using as periods 10 and 20. One of the problems I see in the OBV is that it counts the volume based on the closing price, but I think that It is more appropriate to adjust the sum based on whether the price is above 50% of the total range. On the other hand, the volume may lead to a mistake, so perhaps, capitalization should be used (closing * volume).

I need help, what would be the code of the OBV indicator?

When the second day’s price closes above the prior day’s close,

OBV=Previous OBV+Current trading volume

If prices close lower on the second day,

OBV=Previous OBV−Current trading volume

But what code would it be?

That could be coded like this: (not tested)
```
//When the second day’s price closes above the prior day’s close,
if close>close[1] then 
 OBV=OBV+volume
else 
//If prices close lower on the second day,
 OBV=OBV−volume
endif 

return OBV
```

Thanks

But I don’t understand, do we need to recalculate the OBV or can we use the function already programmed by prorealtime?

The problem comes that screener indicates stocks that are not between ATL and 2 ATL.

And I don’t understand where the problem comes from
