Hi JCL,

I cannot make sense of how StartWeek/EndWeek work. The following code generates strange results (See attached).

1) In both cases, the last bar of the week is 20:59. Why?
2) In both cases, the week does not start from 21:17. Why?
3) On 16/12/02-04, there is a "Weekend bar" (appearing as Sun, 22:00) - which has the start on Fri,20:59 and ends on Fri,22:00...With Weekend>=2 such bar should not have been created.

Please help.

Startweek/endweek only determine which bars are merged, and when you can trade. A weekend bar cannot end friday 22:00, but it can have the price of friday 22:00 when that was still the latest price.

I am trying to understand how these work, and if they work as expected.
It should not have been created at all, according to the manual, with Weekend>=2.

Please let's also clarify the first 2 questions.
