My favorite features are:
100 favorites lists (up to 500 issues per list)
I keep favorites lists in two ways -- by issue and by time frame. So, for example, I have favorites lists which contain all of my "usual suspects" (i.e., indices and key stocks) in 1, 5, 10, 15, 30, 60, 120, and 240 minute plus daily, weekly, and monthly time frames. (To be clear, each chart in each of these lists has the same time frame and indicators. This lets me see what is going on across the markets in any time frame I want.
The second way I keep lists is by individual index or issue, with each one done in all of the above-mentioned time frames. This lets me see what is going on within a specific issue at all levels of time.
Annotating & Saving
You may have noticed that I like to annotate charts a little bit. (G) Having an Extra membership means that I can have as many as 50,000 annotated charts saved at once -- and each one updates automatically. (Okay, I don't think I'll every get near to having THAT many annotated charts. But it's dang convenient to know I'll never run out of room for the buggers. Plus, just knowing that I can have that many annotated charts -- if I wanted to -- helps me to forget that they clipped my dingies off when I was a puppy.
Real Time Charts
Rather valuable for rather obvious reasons, me thinks.
