Foghorn reads world events, company news and SEC filings, then calls up or down on the stocks they touch. Every call is timestamped before the market reacts, and every hit and miss goes on a public scorecard.
Free plan, no card needed.
Real calls from the public ledger, judged on IEX closing prices. Still being tested: please don't trade on them.
Headlines, SEC filings and global event data about the same thing become one event, so ten articles never make ten calls.
Company news names its ticker. World events use an exposure map: an oil shock hits airlines and oil producers in opposite ways.
Up, down or no call, over 1 and 5 trading days, with a confidence level. We only call when the signal is strong.
Each call is timestamped and chained to the one before it, before the market reacts. Nothing can be edited later.
Each call carries a fingerprint of itself and of the call before it. Change one old call and every fingerprint after it breaks. Once a day the latest fingerprint is stamped into the Bitcoin blockchain, which no one can edit, so the history can't be quietly rewritten.
271 calls in the ledger. Stamped into Bitcoin every day; latest Oct 30, block 973,872.
