Using ahead bars for calculating current bar indicator

  Hello,

  I always thought that in ProRealTime I could not use the the values of bars of next week (d+5), next month (d+20) and so on, for calculating the current bar (d) of a calculated indicator.

  However, I am surprised to see that in the Darvas boxes indicator bellow, PRT is able to do so.

  In an uptrend ticker, the top-left corner of a box is derived from the highest value of a bar some days ahead. How can this be possible.

  Could you please explain the mechanism used?

  Thank you in advance

  Vicente

  Because this indicator use DPO to know in advance the ahead bars of the price. DPO is known to use future prices, so in this case its values are reversed to get prices and use it in a different manner.
