sell
Open a short, or close a long when the script is long only.
sell sell below expr [for N bars] sell above expr [for N bars]
Inside a when body. Draws a Sell (or Exit, when long only) arrow and the fill price automatically. long only turns sell into an exit. Two-way scripts flip: sell while long closes long and opens short. A second sell while already short is ignored until a buy. short only uses sell as the entry. sell below X places a sell stop and sell above X a sell limit, with the same timing and lifetime as buy above / buy below. With long only, a sell order is a resting exit for the long and is dropped while flat.
