I really love the think or swim platform from TDAmeritrade. Hated it when Scottrade was bought out because I had to learn the platform but after I did I was like "damn, I can't believe I used the shitty Scottrade for so long!" :-D You can set up a daily chart for what ever date you want and I for me I tend to see more when I use the chart with L2 showing. For whatever reason compacting the chart w/ L2 showing tends to give me a better idea for what could happen!
