FAQ

Questions people ask first.

Does GSDAQ tell me what to buy?

No. Signals explain historical patterns and the conditions to review. They are not personal buy or sell recommendations.

Which brokers work with the screenshot import?

It reads Korean or English brokerage screenshots. Check the ticker and quantity before saving.

Where does the data come from?

Quotes from public market feeds (about 15 minutes delayed in charts), the GSDAQ research pipeline for quality scores, signals and reports, and institutional holdings from public 13F filings.

Is there an Android version?

iPhone first (iOS 15 or later). Android is on the roadmap.
