// 5. ADDITIONAL PARTIAL EXITS / STOPS
// ======================================================================
// You can add partial exits for shorts or longs similarly.
// For example:
// if strategy.position_size < 0 and close > stop_level_for_short
//     strategy.close("Short", qty_percent=50)
