Imagine you're a senior FX trader at a hedge fund. Recently, the currency of an emerging market country, let's call it 'Arcadia,' has experienced significant depreciation due to capital outflows and falling commodity prices. Arcadia's central bank has publicly committed to intervening 'at all costs' to stabilize the exchange rate and has already conducted some small-scale interventions using its foreign exchange reserves. However, the market widely debates the effectiveness and sustainability of these interventions. Design a trading strategy for Arcadia's currency. Elaborate on your directional view, specific trade execution, risk management framework, and contingency plans for various scenarios.

设想你是某对冲基金的资深外汇交易员。最近，某新兴市场国家（比如虚构的“阿卡迪亚”）的货币因资本外流和商品价格下跌而大幅贬值。该国央行已公开表示将“不惜一切代价”干预市场以稳定汇率，并已动用部分外汇储备进行小规模干预。然而，市场对干预的有效性和可持续性存在广泛争议。 请你设计一套针对阿卡迪亚货币的交易策略，详细说明你的方向性判断、具体交易操作、风险管理措施以及在不同情景下的应变计划。
