# Traders' Tips from TASC Magazine

Massimiliano Scorpio’s article, “Targeting Your Pattern,” describes a Easy Language Show Me study to analyze price patterns. Below is the formula to create a MetaStock Expert Advisor version of this study. Most of the Expert Advisor is contained in the Commentary and will produce a display similar to the example shown here. This is a mix of formatted text and formulas. You do not have to format your display to exactly match the sample output. Bolded and underlined text and bullets were used for esthetics but are not required. To create the Expert Advisor in MetaStock:

2. Click New to open the Expert Editor for a new expert.
4. Type a name for the expert, like "Pattern Analysis"
5. Click the Commentary tab.
6. Enter the following text:
