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.
Trade plan
Decide the exit before you enter. Set what you are willing to lose first, and the share count follows — so you know the worst case before you buy.
Fill entry, stop, account size and risk percent to get a share count. The stop must sit below the entry.
This is a calculator, not advice, and it does not promise any outcome. You choose the stop and target — the button values (ATR, recent low/high) are observations from past prices. Actual fills depend on the order book and liquidity.
