Over the next 3 weeks, various countries will begin (or end) Daylight Saving Time (DST), turning their clocks forward or back, as the case may be — and, in the process, shifting their trading session times forward or back – by one hour.
Then, in the Fall, all these time changes will be reversed on various dates, beginning in late September.
We have been tracking these time changes for several years, and by now you know how to make the necessary adjustments in your trading. All you need is a schedule of the changes which are coming.
