XTB xAPI开仓交易offset与sl参数配置问题求助

问题详情 #

卖出单（做空）正常表现 #

卖出交易（cmd=1、type=0）设置offset=50、sl=50时，可正常开启5点追踪止损，符合预期。

买入单（做多）异常情况 #

买入交易（cmd=0、type=0）尝试多组offset与sl组合均未实现预期追踪止损：

• offset=-50、sl=-50：成功开仓但未触发止损
• offset=50、sl=50：返回"无效sl/tp值"错误
• offset=1、sl=-50：返回"无效追踪止损"错误
• offset=0/-1/-10搭配sl=-50：成功开仓但无止损

个人判断买入单的sl需设为负值（止损价低于开仓价），但对offset参数的配置逻辑存疑，原本预期offset=-50、sl=-50的组合可正常生效。

额外需求 #

求比xApi playground更详细的xAPI官方资料，XTB客服未提供相关API技术支持。
