Hi, does anyone know what the is code " Sum( volume( period= week ) " is calculating and how to translate it into googlefinance?

i tried sum of total daily volume, but that isn't correct.

thanks.

Solution
The correct syntax is: def Data = Sum( volume(period = AggregationPeriod.WEEK));

As @halcyonguy pointed out the default number of bars being summed in the sum() is 12 bars. So the above is attempting to sum the 12 weekly bars.
For several reasons, the above definition will not match other sites.

1. statements that use secondary aggregations are called "MTF" indicators.
MTF indicators are repainting every tick until the week closes.

2. the various apps (ToS, Tradestation, etc...) data feeds have never been able to be made to align with Google. It would seem that this is a known issue. However, there is no total agreement as to why.

you don't have a length specified, for how many bars to add up...
the defaut length for sum() is 12, so 12 bars of data.
period = week, means to read data from a different aggregation, a different time. a week.
so add up the volumes over 12 weeks.

Thanks for the response. That's what I thought but it's not what the outcome is. Wondering if I was missing something. The formula doesn't use length in this case, so presuming it's an overall volume of chart?
