| | | * Gate 模块统一配置。 |
| | | * Gate 交易模块全局配置,策略的唯一参数入口。 |
| | | * |
| | | * <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>定位</h3> |
| | | * 通过 Builder 模式将所有运行参数集中管理,避免策略参数散落在多个类中。 |
| | | * 运行时动态参数(step、gridElements、baseLongTraderParam、baseShortTraderParam) |
| | | * 由 {@link GateGridTradeService} 在策略执行过程中写入。 |
| | | * |
| | | * <h3>关键参数</h3> |
| | | * <h3>参数分类</h3> |
| | | * <table> |
| | | * <tr><th>类别</th><th>参数</th><th>用途</th></tr> |
| | | * <tr><td>认证</td><td>apiKey, apiSecret</td><td>REST/WS 签名认证</td></tr> |
| | | * <tr><td>交易标的</td><td>contract, leverage, quantity, contractMultiplier</td><td>合约、杠杆、张数、乘数</td></tr> |
| | | * <tr><td>持仓</td><td>marginMode, positionMode</td><td>全仓/逐仓、单向/双向</td></tr> |
| | | * <tr><td>网格策略</td><td>gridRate, gridQueueSize, priceScale</td><td>间距比例、队列容量、价格精度(交易所tick)</td></tr> |
| | | * <tr><td>止盈止损</td><td>overallTp, maxLoss</td><td>整体止盈/亏损阈值(USDT),触发后策略停止</td></tr> |
| | | * <tr><td>风控</td><td>marginRatioLimit, reopenMaxRetries</td><td>保证金占比上限、补仓重试次数</td></tr> |
| | | * <tr><td>盈亏计算</td><td>contractMultiplier, unrealizedPnlPriceMode</td><td>合约乘数、未实现盈亏计价模式</td></tr> |
| | | * <tr><td>运行时</td><td>step, gridElements, baseLongTraderParam, baseShortTraderParam</td><td>由策略动态填充</td></tr> |
| | | * </table> |
| | | * |
| | | * <h3>priceScale 说明</h3> |
| | | * 价格精度表示交易所允许的最小价格单位的小数位数: |
| | | * <ul> |
| | | * <li><b>网格参数</b>:gridRate(比例间距)、step(绝对步长 = shortBaseEntryPrice × gridRate,运行时计算)、 |
| | | * gridQueueSize(队列容量)</li> |
| | | * <li><b>止盈止损</b>:overallTp(整体止盈 USDT)、maxLoss(最大亏损 USDT)</li> |
| | | * <li><b>风险控制</b>:marginRatioLimit(保证金占比上限,超限跳过开仓)、leverage(杠杆)、 |
| | | * marginMode(全仓/逐仓)、positionMode(单向/双向)</li> |
| | | * <li><b>盈亏计算</b>:contractMultiplier(合约乘数)、unrealizedPnlPriceMode(计价模式:最新价/标记价)</li> |
| | | * <li>XAU_USDT: tick=0.1 → priceScale=1</li> |
| | | * <li>ETH_USDT: tick=0.01 → priceScale=2</li> |
| | | * </ul> |
| | | * 所有价格计算必须对齐到 tick 整数倍,否则 Gate API 返回 |
| | | * {@code invalid argument: trigger.price price is not an integer multiple of a price unit}。 |
| | | * |
| | | * <h3>使用示例</h3> |
| | | * <pre> |
| | | * GateConfig config = GateConfig.builder() |
| | | * .apiKey("...") |
| | | * .apiSecret("...") |
| | | * .contract("ETH_USDT") |
| | | * .leverage("100") |
| | | * .gridRate(new BigDecimal("0.0035")) |
| | | * .contractMultiplier("0.01") |
| | | * .isProduction(false) |
| | | * .build(); |
| | | * </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> |
| | | * <h3>gridElements 生命周期</h3> |
| | | * <ol> |
| | | * <li>项目启动时初始化为空 ArrayList</li> |
| | | * <li>{@code tryGenerateQueues()} 中通过 {@code updateGridElements()} 填充,同时触发 |
| | | * {@link GridElement#rebuildIndex(List)} 建立全局 O(1) 索引</li> |
| | | * <li>每次挂单/止盈操作后通过 {@link GridElement#refreshIndices()} 更新索引</li> |
| | | * </ol> |
