Free trade desk and signal engine research
Passkey only — your own device creates it and keeps it. No password, no email, no personal data collected: an account is a handle you pick and a key that never leaves your device. You get $100,000 in play money to trade the model’s signals.
Educational and entertainment statistics only. Not investment advice. This is a research model showing its work, for learning and paper trading. It does not know you or your situation, and nothing here is a recommendation to buy or sell.
What this is
GSS is a free paper-trading platform and paired research engine that scores, tests, and records stock trades. It works in two stages, and they are separate. First the pre-market scan reads roughly 1,500 stocks and picks the day’s strongest names, which join a hand-curated list to form that day’s watchlist. Then the model works that watchlist and nothing else: it builds a statistical signature for each name and scores it against the structures we favor, using price trends, trade volume, and moving averages to measure momentum that is already under way.
Research access is next
The paid tier will provide engine results for 4-Hour and 1-Day timeframes and a daily fifteen-name list from the pre-market scan, alphabetical and unranked — $17/mo, opening January 2027.
No trackers, no cookie banner. We store your email, where you found us, and which product you picked — nothing else.
For developers and agents
The board is plain JSON at api.greensandstrategies.net/v2/signals. No key on the free tier — delayed and rate-limited. Derived datasets such as label overlays, regime history and calibration sets are coming to the shop. We never sell raw price history.
