Monthly Stochastic X-Up

Here's a blog entry from a while ago that explains crossover scans:

The other trick you need to know is how to modify the time frame for an indicator in a scan. If you just use the indicator by itself, e.g.

Fast Stoch %K(14,3)

then the scan engine assumes you mean the daily time frame and uses daily data.

If you want a different time frame, and all the parameters in the indicator are numbers, like the %K example above, then you have to modify the indicator with a time frame specifier before it, e.g.

monthly Fast Stoch %K(14,3)

But if any parameters are text, then you have to modify BOTH the indicator AND the text parameter, e.g.

weekly sma(13, weekly close)

When you are writing a scan in the Advanced Scan Workbench, you can select any term you want, including technical indicators like Fast/Slow/Full %K and %D, from the drop downs in the "Scan Builder" section under the Scan Criteria window and the click on "Insert". A default version of the selected item will appear below any existing text in the Scan Criteria window. You may have to edit the default text and/or cut and paste it into your existing scan text. For example, in your case you will have to arrange %K and 20, and %K and %D around an "x" operator.
