This stock has not flashed this signal recently — the record above is the signal’s own, not this stock’s.
Entry is the latest close at publish time; next-day is the following close. “Market” is the equal-weighted average of every stock in the same market that day; delisted names are excluded from both. Fees, taxes and slippage are not included. An observed record over a short window, not a pre-registered backtest. Not investment advice.
