/**
|
* Gate 模块统一配置。
|
*
|
* <p>通过 Builder 模式集中管理所有运行参数，避免参数散落在多个文件中。
|
* 提供 REST API 和 WebSocket 地址的自动环境切换（测试网/生产网）。
|
*
|
* <h3>使用示例</h3>
|
* <pre>
|
* GateConfig config = GateConfig.builder()
|
* .apiKey("...")
|
* .apiSecret("...")
|
* .contract("XAU_USDT")
|
* .leverage("100")
|
* .gridRate(new BigDecimal("0.0035"))
|
* .contractMultiplier("0.001")
|
* .isProduction(false)
|
* .build();
|
*
|
* String restUrl = config.getRestBasePath(); // 自动返回测试网或生产网地址
|
* String wsUrl = config.getWsUrl();
|
* </pre>
|
*
|
* <h3>默认值</h3>
|
* <ul>
|
* <li>合约: BTC_USDT, 杠杆: 10x, 全仓, 双向持仓</li>
|
* <li>网格间距: 0.35%, 队列容量: 50, 保证金比例上限: 20%</li>
|
* <li>止盈: 0.5 USDT, 亏损上限: 7.5 USDT</li>
|
* <li>数量: 1 张, 合约乘数: 0.001, 环境: 测试网</li>
|
* </ul>
