[BlindMath] What do you use for drawing conclusions from charts, for example from price actions?

[Godfrey, Jonathan]

Hello,

I wouldn't use a chart at all.

I'd be collecting the data in as close to real time as I could and doing the data munching myself in R, with the final step to push it to a web page with the most important results being put at the top of the tables I create. Other people would do similar things using their programming language of choice.

If you were really serious about the process of tracking prices in real time, the things you could set up are pretty limitless.

Personally, I would want to be notified of anything that was of material importance to what I already owned, followed by what I might want to own. I would want that to be filtered by my ability and desire to respond; that is, I only want information at the rate I can deal with it.

In constructing a system for myself, or a client, I'd be asking what the graphics are supposedly highlighting for the sighted world. In this context, if it can be graphed, it can be tabulated. My ordering of a table would be very different for my needs as compared to a sighted person who can quickly scan down a  bunch of numbers, or be drawn to highlighted details. Even if a sighted client wanted graphs, I'd want to ensure the graphs that were being scanned by the sighted people were the ones that were material to them. There are thousands of prices that people want to watch in numerous trading situations. Even a  sighted person can't look at 500 stock prices at a glance.

Hi,
I've been reading up on trading, and one of the things I've noticed is that sighted people use the price action (which is a chart displaying how the prices have mincreased/decreased in a period) to quickly draw conclusions.
For example, "in the last 3 days, the price has reached to around $3.5 and then dropped to around $2.2." or "the price has gone up for about 15 minutes after the market opened, and then it has gone down."
These things are very quick to see in a chart, but you don't necessarily get these insights if you were to have the data in a table.
What do you use for drawing insights from data like this, where visualization seems to provide answers very quickly?
Thanks,
Parham
