Total number of bars

  Hi guys,

  I made an indicator with Centered Mobile Averages and to translate the data I have to know how many bars are on the graph, and I use:

  return barindex

  just know the exact number (it changes on different graphs)

  Is there anyway to solve this?

  Thanks

  BARINDEX will always return the bars quantity of the opened chart. So sorry if I don’t understand but what do you want to do exactly please? Because if you use BARINDEX as your period for your moving average, it will instantly calculate the good mean for all the data displayed on your chart.

  Usually i read the number of total bars and then write it on my indicator as a parameter (see image).

  If I use barindex as a variable inside the code it doesn’t work because it has a different number for every bar, but I want just the last one.

  Translation

  REM traslazione if (barindex <= numbars - indietro) and (barindex > indietro) then //numbars = total number of bars seen from barindex if indietro = 0 then ind = close elsif indietro = 1 then ind = -DPO[1](close)+close elsif indietro = 2 then ind = 2*(-DPO[2](close)+close) - (-DPO[1](close)+close) else ind = (2*indietro-2)*(-DPO[2*indietro-2](close)+close) - (2*indietro-4)*(-DPO[2*indietro-4](close)+close)-close[indietro-3] endif //ind1 = round(ind) ind1=ind else if barindex<= indietro then ind1 = undefined else ind1 =ind1[1] endif endif return ind1 as "traslazione"

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

  REM traslazione   if (barindex <= numbars - indietro) and (barindex > indietro) then   //numbars = total number of bars seen from barindex if indietro = 0 then ind = close elsif indietro = 1 then ind = -DPO[1](close)+close elsif indietro = 2 then ind = 2*(-DPO[2](close)+close) - (-DPO[1](close)+close) else ind = (2*indietro-2)*(-DPO[2*indietro-2](close)+close) - (2*indietro-4)*(-DPO[2*indietro-4](close)+close)-close[indietro-3] endif //ind1 = round(ind) ind1=ind else if barindex<= indietro then ind1 = undefined else ind1 =ind1[1] endif endif   return ind1 as "traslazione"

  To know if you are on the last bar of the chart, you can use the code snippet below:

  LastBarOnChart=currenttime=opentime and date=today return LastBarOnChart

  1 2	LastBarOnChart=currenttime=opentime and date=today return LastBarOnChart

  But because the history is only read once, in your case, you will not be able to use it as a period for your indicator automatically. Another way would be to make loop in the past starting only on the current bar and with the last barindex as the period.. But still, ProBuilder doesn’t allow to plot curves in the past..
