New version 1.11 now available

For people day trading stocks and focusing on gapping/momentum stocks, the daily process of building a watch list of candidates likely to yield good trade setups is critical.

There are multiple sources that yield different results for the same scanning filter. Using only one source will miss promising stocks and dealing with multiple sources is hard to manage in a timely manner with repeat hits on discarded stocks. Alternative sources are also an essential backup when failure occurs with some of the primary data sites.

SpiderScan was written to build a daily watch list of stocks with the click of a button, consistently, almost instantly, keeping track of stocks that already came up in a previous scan and highlighting new ones. A few clicks of the mouse creates a watch list from multiple scanners and data parsed from multiple sources and websites. The program spiders through websites at lightning speed compared to manual browsing.

SpiderScan aggregates real time, historical and fundamental data from multiple sites into an optimized screen to quickly isolate promising trade candidates. All scans are easily customized with filters to adapt to any market conditions.

Market opens with a big gap up ?
Increase the minimum gap and/or the minimum volume criteria to avoid excessively large lists.

Want to concentrate on stocks gapping outside of the previous day's range ?
The price open column when present is color coded according to the range.

SpiderScan has a database of 7000 stocks and ETFs classified by sector and industries. React quickly to news affecting an industry.

Oil shooting up ?
Check out the airlines. Bring up the Industry scan, expand the Transportation sector and select the airline industry, a snapshot list of the top movers comes up instantly with realtime data.

Want to look for sympathy plays ?
Bring up a list of top movers for a stock's sector or industry in seconds. Filters ensure that low volume and/or price stocks are not displayed if unwanted.

SpiderScan also interfaces nicely with QuoteTracker(QT) and Interactive Brokers TWS(IB) if these program are used. Link to charts in QT and survey a stock chart just by selecting it in SpiderScan.

Chart looks promising ?
Press the SPACE bar and the stock is in your QuoteTracker watch list. On each scan screen, stocks currently in your QuoteTracker portfolio are color coded.
While cycling through your charts of stocks through SpiderScan's Watch List (QT only) highlight a sub list of promising stocks and quickly rotate between them when near chart bar completion. Instantly calculate share size according to risk and bar data (QT only). Press a key and instantly fill a limit stop order with an associated stop loss in IB (IB only).

At the end of the trading day, see a stock on a blog where somebody made a killing ?
Wondering why it did not make it into your watch list ?
SpiderScan allows saving and restoring all scans performed during the day. Go back to your scans, see if and when that stock came up, figure out why it did not make it into your list.
At the end of the week, month, recall scans and watch list(QT only) to analyze trading performance.

SpiderScan Demo Videos

The Briefing.com scan can be run pre-market or after the open. Here is a video for today's scan. Put the volume up... I am narrating. Notice how fast the scan is compared to manually extracting the data. Now supports older Platinum subscriptions as well as the new In Play format.

Here is a video on Ibscan, which uses Interactive Brokers's desktop API to query their scanner. You obviously need IB to use this scan.

The Sector and the Industry scans based on Google Finance are very powerful to zoom into market action. Data is real time.

The Finviz scan from Finviz.com is a great free scan. They also have a paid subscription for a real time version of their screener.

Prophet from prophet.net is another highly customizable scanner.

Two quick and reliable scans straight from the web. Inet and Quote. Inet is actually a good pre-market scanner.

Prem, a new real time pre-market scan from free sources, no data subscriptions required.

Gap history tool
, a new research and review tool to get historical gap lists. Not released yet, to be released soon.

How much resources does this occupied?

The CPU and memory foot print is very small. Spiders are like a browser, no streaming data just request-response interaction. The real time data sources are snapshot XML data.
