I use stockcharts.com with 14$ a month subscription. You can monitor the chart by 1-5-10-15-30-60 mins on to daily weekly and monthly.
For chart analysis most of the time I look at the 60min and then daily and sometimes the weekly to see how the stock is doing.
You can watch the MACD forming a cross on a stock but it should not be your only indicator, I use the MACD, RSI, Williams %r and Volume they all work together.
Technical_Indicator has some good videos stickied up on the board if you haven't watched them already.
