Cumulative Sum for all history

  Is there a way for “cumsum” to lookback for complete Data history..?

  I don’t know if a simple summation[barindex](array) could do the trick, I don’t think so…  but…   This is for a kind of Accumulation/Distribution index for returns, but cumsum function only use data loaded on chart as described in reference manual.   I need to force as much history by code if possible  (I’ll wish that to force this on daily timeframe, but I know this is only possible for proscreener code)  🙁

  EXAMPLE:

  RC = cumsum((close/close[1])-1) RETURN RC AS "DAILY RETURNS"

  1 2	RC = cumsum((close/close[1])-1) RETURN RC AS "DAILY RETURNS"

  Thanks in Advance mates..!  😉

  There is no kinda instruction to force history load in Probuilder.

  But you could make a loop in x previous bars to force by yourself the cumulation of theses x bars.
