Newbie here. Because forex trades pretty much 24/5, you have 3 different sessions. When you look at a daily chart does each sessions have its own daily bar or does the daily bar you see on a daily chart reflect the whole 24 hr day. In other words…New York, London and Asia trading all represent singular bar, or each session has its own daily bar.
For the vast majority of brokers, each bar represents a 24 hour period. That doesn’t necessarily mean that the broker has the same start/stop time for each bar as every other broker, that will mostly depend on the time zone in which the broker is located.
Look on your chart and see if the close of one bar is almost always the open of the next bar and you will be able to see. If there are gaps, then it represents only sessions. I would avoid brokers that only off this, because the data will only depict one session rather than the honest market as it is always moving.
