Stopped-out heat

// Where stops ran, as zones behind the candles: the longs and the shorts closed at a loss or forced
// out at each price, from each fill's `takerWhy`. Each value fades over later bars; set Carry to Hold
// in the heat's settings to keep each stop run drawn until price trades back through it.
