Cumulative Sum for all history

xel · 2016-05-30T21:52:08+00:00

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" 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.
