I believe that backtesting always shows date/time (graphs, transactions, positions, logs) in local time (where local is web browser/computer locale).
While this can be useful, often the user likes to see everything in stock exchange time zone. It would be great to have the option to choose.
Feature request: current locale vs stock exchange timezone selection
Thanks Luca for the request! I've heard it a couple times before and I agree the timzones can get confusing. I'll add your vote to the suggestion.

Initially I thought it was just a matter of remembering to subtract/add a bunch of hours, but actually this timezone changes completely the way you look at your daily graphs, positions, transactions. Let me explain it better.
Because I live in Australia, when timezone is taken into account, a single trading day in NY runs from the night and the following morning of a day in Australia. A NY trading day is split in two different days in Australia. This means that daily statistics, positions, transactions and graphs seen in Australia contain information from two different days of NY: each Australian daily information contains data from end of previous NY trading day and data from start of current NY trading day.
Suppose I have an algorithm that trades at market open and close, if I look at statistics with Australia timezone they are very different from the same statistics seen in NY.
