该组件现在通过 Version 属性（默认值：2）支持 WebSocket API v2。
套接字打开后，您可以通过发送经过身份验证的订阅请求消息来订阅私有数据频道。
API 客户端必须通过以下 REST API 端点"GetWebSocketsToken"请求认证"令牌"，才能连接到 WebSockets 私有端点。该令牌应在创建后 15 分钟内使用。一旦与 WebSockets API 私有消息（openOrders 或 ownTrades）保持连接，令牌不会过期。
要获取 WebSockets 令牌，必须在 Kraken Options 组件中设置 API Key 和 API Secret，即您账户中 Kraken 提供的 API 密钥
Kraken.ApiKey := 'api key';
Kraken.ApiSecret := 'api secret';获取自有交易列表，首次订阅时获取最新 50 笔交易列表
SubscribeOwnTrades();之后，您可以调用 UnSubscribeOwnTrades 方法取消订阅 OwnTrades
