I echo what Bullan has asked for and I have long found it similarly frustrating.
The Issue is caused if there have been large Range bars in the past followed by short range bars and so the scale fixes itself to show the full long range bars, whereas I want to see the detail of recent short range bars, but still see the overall price curve over 100 bars etc
I get around it by reducing the number of bars I show on the chart down to 25. but this is far from ideal.
I only quickly scan read Bullan’s posts, so apologies if above does not describe the same Issue?
