Are hourly charts accurate ?

Most of the websites including stockcharts first interval is from 9.30 to 10 am for hourly charts /

Are these truly hourly charts as it seems that first candlestick of the day is half hour period.

Can someone help me or tell me can i trust these charts ?

or is there any website which has true hourly charts ?

What market are you looking at?

US stock markets ( nasdaq / nyse)

All charts are "accurate".

They are just a way of displaying data - all time frames are artificial. They have no reality other than that which we ascribe to them.

In practical trading terms, longer time frames may be easier and they also of course contain more data.It just depends on how you want use them.

For what it's worth, I don't really see timeframe as important, or at least not as important as recognising the limitations of yourself and your selected charts.

First hourly bar should be the 10:30 bar.

It's the last bar of the day that gets truncated if the day ends before the alloted time.

stockcharts or most services show first bar at 10 for hourly charts ?
