Here are two scans I use frequently that my trading partner set-up and shared with me:
"TAZ" LONG $5 -$15
[type = stock] and [country = us] and[daily ema(60,daily volume) > 150000] and [daily high <> ema(30, close)]and [daily close > daily ema(30,daily close)]and [daily close <> daily sma(200,daily close)]and [weekly sma(10,weekly close) > weekly ema(30,weekly close)]and [ADX Line(10) > 20.0]and [close >= 5]and [close <= 15]
"TAZ" SHORT $5 - $15
[type = stock] and [country = us] and[daily ema(60,daily volume) > 150000] and [daily low > yesterday's daily low] and [yesterday's daily low > 2 days ago daily low] and [SMA(10, close) <> daily SMA(10,daily close)]and [daily close <> 20.0]and [close >= 5]and [close <= 15]
Scanning the market is very simple but unfortunately it is not free. A membership with Stockcharts.com is $24.95 per month for the scan engine service. However, like commission you pay to brokerage firms, that's just part of the investment. Its not what it costs you but what it's going to make you... within reason of course!
