// Purpose: a trade managed with resting exits. A breakout enters on a stop order that carries its own bracket; half of the position is taken at a
// limit above (post-only, withdrawn if it has not filled in 20 minutes), and what remains leaves through a stop-limit if price falls back under the
// range. Each exit is an order of the account, linked to the position it leaves: it never trades more than the position holds and goes if the
// position is closed first. While one rests, the book reads `Closing`, so the rule that waits for `Exposure.Open` does not stack a second exit on it.
//
//   ENTRY    a buy stop at the range high (`OrderType.Stop`), with a target and a stop on the position it opens (`Protect.Bracket`).
//   SCALE    half taken at a post-only limit one range above the entry, expiring in 20 minutes (`OrderOption.PostOnly`, `OrderOption.Expire`).
//   EXIT     the rest through a stop-limit under the range high (`OrderType.StopLimit`).
//
// HONEST NOTE: written to the specification and checked that it compiles and runs on a dataset; its edge has not been measured.
// Category: host
// Permissions: orders.submit
// Preconditions: a market whose aggregated prints the terminal has, from before the day's open, or a dataset holding aggTrades.
// Side effects: asks the terminal to run the strategy on that market; once running it places orders on the account the person chose.
// Run: Add script on the Market Replay window or the title bar's script icon; Insert strategy in the Datasets window (backtest).
