I'll give you a quick run down of what it does/how it works.
When first loaded, you select timeframes and assets.
You can use the arrows to pick all of a timeframe (example here is daily) or all of an asset (example here is EURUSD). Or you can manually tick or untick them. It will load all assets in the marketwatch.
After that, it will ask you what patterns you want to use.
You can pick certain patterns and what direction you'd like to scan for them.
Once you start the scan, it will then automatically open each chart to be scanned (note, it will open them. This can be great if your selective but if you just scanned the entire market 1 hour - 1 week,, you'd have a bunch of open charts).
When it is done, it will present you with three types of patterns.
1 - Old (Completed patterns, you can see how well they would have done)
2 - Tradable (Patterns that are trading inside the harmonic set up)
3 - Developing (Potential eemerging patterns)
When you click the arrow to select one, it takes you to the alrady opened chart which has had the pattern marked into it.
Targets shown in green lines and stop in red (by default settings)
The settings have everything from very basic to extemely specific customing options.
