Startup ATL + OBV = Wickoff+ Weinstein

  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 + OBV 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 ]

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

  //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 ]

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

  //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

  test

  //ATL All time low identification ATL = lowest[max(1,BarIndex)](low)

  1 2	//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​

  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​

  1 2 3 4 5 6 7 8 9

  //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
