If i use for example the built-in study "Trendline Automatic" on a 233T chart on the @es for the last 8 days (about 5800 bars) with History on "yes", and then right click on Format Drawings i see that over 650 trendlines are plotted.
Is there an easy solution, for other codes as well, to reduce the drawings to the last 30 lines without changing the chart settings.
