I notice that the beta version of Barchart.com (for subscribers) has a new "Trader's Cheat Sheet" feature that plots prices for any stock, ETF, or futures contract on a vertical ladder, along with pivot-point based support and resistance levels; 4, 13, and 52 week high and low prices; and the prices at which particular technical indicators would provide signals.
It's a nice way of organizing price level information; I'll be playing with it in the days ahead and reporting on any findings. Above is part of the cheat sheet for the S&P 500 Index (SPY).
