The object of the scanner is to identify profitable investments by highlighting companies whose share prices are performing according to specified criteria.
Scans can be designed around price, moving average, stop loss, RSI, MACD and OBOS. Combinations of these criteria within a single scan can be saved and recalled for future use, and give you a powerful tool to search the price database.
The scan+ upgrade has added further scans based on ADX, volatility, meisels, momuntum and stochastics. It has also added new scanning methods. In addition to looking for the indicator being above, below or either side of a trigger level it can also check whether the indicator is rising or falling or has peaked or troughed over a given period of time.
Scans can now be based on island and key patterns occuring at the top or bottom of a trend. These are good indicators of a change in direction of a trend, or turning points.
For example, a simple scan could allow you to display a list of all companies whose share price has risen by 50% over the last 6 months.
A more complex scan could combine price change and RSI to display companies whose share price has risen by 75% over the last 6 months and whose 35 day RSI is below 45 and rising.
In other words the share price is performing well but has suffered a recent setback.
Other scans may be used to determine traditional buy or sell signals, such as, the 20 day moving average has risen above the 55 day moving average in the last 10 days. This could be narrowed down to exclude all companies with a price below 100p, say.
The various tasks that can be performed by the scanner are listed below. Any number of these tasks can be combined into a single scan. This scan description can then be saved and recalled for future use. Scans are designed to be appplied to groups of shares eg. Prestel, teletext3000, your own portfolio. The result of a scan can be displayed alphabetically or sorted by any element of the scan such as price, RSI, MA etc.

The scanner can be used to look through all the shares in any portfolio to find potential trading opportunities. Applying this to a system portfolio lets you scan the entire market in one operation.
A scan file can hold any number of criteria, each of which can be based on price, moving average, stop loss, RSI, MACD or OBOS. Scan files can be created, saved, retrieved and deleted. Scan criteria can be added, deleted and edited.
To define a scan, right-click on any share in the portfolio and select scanner / setup from the drop-down menu. The following dialog box will be displayed.
To start scanning, right-click on any share in the portfolio and select scanner / go from the drop-down menu.

Todelete the current scan file, click on the "delete" button.
Tosave the current scan file, click on the "save" button.
Toadd a new scan criterion click on the "add a scan line" button. The dialog box shown below will be displayed.
Toedit the current scan criterion click on the "add a scan line" button. The dialog box shown below will be displayed.
