Now I wish to use my fond recollections of early SCT writings as an example of the need to transition some trading information from the visual sphere to the auditory cube. I currently enjoy early-onset Alzheimer's, so bear with me on the details. As we say in Texas, "If it ain't true, it oughta be".
Jack had at least the following:
5 minute ES chart
ES volume pane
custom stochastics pane
RSI pane
depth of market window
5 minute INDU chart
fast YM chart
annotated with:
volume thresholds for DU and VDU
trend lines and the associated channels
volume trend lines ("gaussians")
plus all the things going on in his head unassisted by charting (if A then B, two pairs, straight flushes, etc.)
I am forgetting or misremembering something, because I once counted 14 things he had to watch.
Now Jack is a very smart guy for his age (older than dirt), and an NLP afficianado like me, so he knew his Dirty Harry philosophy and his limits. And he devised a scheme for periodically "sweeping" all his indicators. My presumption being that his trading universe was too large to grasp tout d'un coup, impossible to form a gestalt from a single glance.
In my own even more absurdly complicated system (11 panes, 33 separate codes, many hundreds of SLOCs, more lines on the screen than on Keith Richards' face), I tried visual "sweeping". It didn't work. First, I could never remember the order. Second, I couldn't resolve conflicts between indicators. Third, I always missed something despite using eye-catching colors (deep sea green, lemon chiffon). So in desperation I started using simple audible alerts. That helped, but the breakthrough was to combine consistent indicators in code and to use unique audibles for each combination. More to cum.
