I am using platinum charts @ icharts..I have used trade tiger and other charting tool with super trend. As told earlier , they differ from tool to tool..
No issue it did gather momentum after some sideways,
Why i asked the question is most of us using Amibroker can configure the first candle to start at 9:15 then it closes at 9:25/9:35 so on,
i have setup session time in Amibroker as 9:00 AM to 3:30, so that 10 mins is aligned with hourly charts, same as what you are getting
