the way to set chart defaults in general is to configure one chart the way you want the default to be set (window size, chart type, frequency, indicators, etc, then on the chart ribbon, TEMPLATES tab, there is button for setting default. if you click it, all new windows after that will use that chart's setting. only other thing is, if you click and drag on the Y axis, that will change the Y Axis from Dynamic mode to one of the other.
