How GSDAQ signals work
What the Long and Short marks and strategy-list changes in GSDAQ mean, which data they use, how often they update and what they cannot tell you.
What is a GSDAQ signal?
This page explains the two signals shown on charts and strategy cards. Long and Short marks on a chart label direction changes found in past prices. Strategy cards report that a stock was added to or removed from a strategy's list. Neither is an order, a promise of future performance or a personal recommendation, and GSDAQ never places trades or holds money. Alerts can also report other rule results, such as a change in the quality model's classification, a theme ETF move or a rule met on a stock you hold or watch; each states what a rule found, not a trade order.
| Signal | What it means | What it is not |
|---|---|---|
| Long mark (↑) | An upward shift found in past prices, from a crossover of the 20- and 60-period EMAs or of MACD (12/26/9). | Not a buy order or a forecast that the price will rise. |
| Short mark (↓) | A downward shift found in past prices, from the same crossovers in the other direction. | Not a sell order and not a suggestion to sell short. |
| Added to strategy | The stock entered a strategy's current list. | Not a buy order. |
| Removed from strategy | The stock left the strategy's list, for example because it fell outside the ranked slots. | Not a sell order; your own holding has not been sold. |
Which strategies produce list signals?
The public feeds follow three strategy lists. Each card names the strategy behind it, so read the reason against that strategy's conditions. The growth trend list is modeled on a published trend screen but is not an official implementation (see our SEPA guide).
| Strategy | What it looks at |
|---|---|
| Growth Trend Agent | SEPA-style growth trend conditions; composite ranking, equal weight. |
| Quality Momentum Agent | Business quality, price momentum and trend conditions. |
| Long-Horizon Signals Agent | Stocks meeting buy/hold conditions; equal weight. |
What data do signals use?
Chart marks are computed on the price intervals shown in the chart, excluding the last interval, which may still be forming. The growth trend list uses daily U.S. price bars. Relative strength is measured against SPY, and company fundamentals are cached for up to seven days. Explanations can also draw on headlines from public news feeds and Federal Reserve press releases, and on institutional holdings from public 13F filings. Chart data is about 15 minutes delayed.
How often do signals update?
The message feed checks for new signals and important news every 15 minutes during U.S. market hours and hourly outside them. Strategy lists are recalculated on U.S. trading days, several times during the session, and on those days news is collected about every 30 minutes. Market data is delayed up to 15 minutes and may be unavailable outside U.S. market hours, so a signal can appear after the price move that produced it.
What does the AI explanation add?
When you ask about a signal, the AI explains the current rule classification, the evidence, the risks and what would change the picture, using numbers from GSDAQ's data and cards. It is instructed not to give personalized buy, sell, add or trim commands. As the Terms state, answers can be wrong, incomplete, out of date, or fabricated, including numbers and quotations. Verify anything you rely on.
What can signals not tell you?
Indicators summarize historical prices and are not trading instructions. The upper, middle and lower paths drawn from similar past patterns are conditional scenarios, not forecasts. Display settings do not change the signal logic, but changing the chart range changes the price intervals being compared, so signals can differ. Signals are not orders and do not establish future performance, and our research method rules out publishing unverified strategy returns.
