Hi Brad. I use only StockCharts and have no knowledge of other systems.
A single keystroke for any strike shows bid/ask for volume of contracts and prices for each. Works pretty rapidly so is most useful by watching the changes for some seconds or a couple of minutes, depending on the activity of that strike. When I have particular interest in only (maybe) a couple, useful information can be added to what I deduce from other indicators on the charts.
Here is a program which is free and actually better then many which charge 200 300 $ a month. Gives you all you need. If you have Etrade account you can use there Data. I have use it side by side with trade station and I was surprised with its capabilities. Tradestation is a Gold standard in charting software.
