/**
|
* Gate REST API 执行器。
|
*
|
* <h3>设计目的</h3>
|
* WebSocket 消息在回调线程中处理(如 {@code WebSocketClient} 的 {@code onMessage} 线程)。
|
* 下单 REST API 调用可能耗时数百毫秒,若同步执行会阻塞 WS 回调线程,导致心跳超时误判。
|
* 本类将所有 REST 调用提交到独立线程池异步执行。
|
*
|
* <h3>回调设计</h3>
|
* 每个下单方法接受 onSuccess/onFailure 两个 Runnable。
|
* 基底开仓时 onSuccess 用于标记基底已开,网格触发时通常为 null(成交状态由仓位推送驱动)。
|
*
|
* <h3>线程模型</h3>
|
* <ul>
|
* <li><b>单线程</b>:保证下单顺序(开多→开空→止盈单),避免并发竞争</li>
|
* <li><b>有界队列 64</b>:防止堆积。极端行情下最多累积 64 个任务</li>
|
* <li><b>CallerRunsPolicy</b>:队列满时由提交线程直接同步执行,形成自然背压</li>
|
* <li><b>allowCoreThreadTimeOut</b>:60s 空闲后线程回收,不浪费资源</li>
|
* </ul>
|
*
|
* <h3>调用链</h3>
|
* <pre>
|
* GateGridTradeService.onKline → executor.openLong/openShort (基底双开 + 网格触发)
|
* GateGridTradeService.onPositionUpdate → executor.placeTakeProfit (开仓成交后设止盈)
|
* GateGridTradeService.stopGrid → executor.cancelAllPriceTriggeredOrders
|
* </pre>
