Hi, I am newbie for trading stock. I am trying to screen stocks using weekly RSI or Weekly MACD indicator, but do not know which website can provide these scan? I know most of website can scan stocks based on daily RSI and MACD. Anybody know how to do these? thanks in advance
I believe Stockfetcher.com has that capability. I used to use them until I moved to trading futures. Anywho, check them out. i think they have free eval for a few days or weeks.
stockcharts.com has load of good stuff for free. Here is their overview of indicators http://stockcharts.com/education/IndicatorAnalysis/
To experiment with different scans and time frame, you also can consider using a standalone screening software.
You could use Wealth Lab for scanning (and also backtesting). You could download EOD data from Yahoo and later when scanning you would switch to weekly timeframe. Just be sure that you never want to switch to intraday trading as Wealth Lab was not designed for this initially (at least its terrible to use it for that, while EOD is somehow okay).
