Hi Mark,
When we draw a trendline we mostly expect the price will react/reverse upon contact in the future. Having to extend manually the trendlines over time is tedious.

so it would be great if trendline extension could be added in Fund Manager.
It seems many programs implement trendline extension in the same manner. So maybe it's not needed to reinvent the wheel here.
- this should not be a global option but an option for each trendline, because there are trendlines that we don't want to extend (only local support/resistance lines)
- in the properties of each trendline, an "Extend" checkbox for each of the left and the right ends. When checked, the line is extended at the right and/or left end, but it is only at the display level, the line keeps in fact its original coordinates.
- to see the real coordinates (ends) of an extended trendline, the corresponding "handles" appear when the mouse come up over the trendline. The handles still allow to manipulate the trendline (its slope) even when it is extended.
- maybe a global option to define if we want new trendlines to be extend by default (and at which ends) or not. Or memorizing the settings for the last edited trendline, and use it by default for a new trendline.
Example in the TradingView program (same in ProRealTime, etc.).
