夜雨聆风周六到了，侠哥继续给大家安排EA源码。
今天分享的这个是以前很火的一款老EA，叫聚宝盆2.0。它属于网格马丁类策略，但不是完全无脑乱开仓，而是加入了均线方向过滤和分组管理逻辑。
先说它的优点。
第一，多空订单分开管理。多单和空单用不同识别编号，统计、加仓、平仓互不干扰，复盘和管理会更清楚。
第二，它不是纯盲网格。首单会参考大周期均线方向，只在符合趋势判断的时候启动，相比那种什么行情都硬开仓的网格EA，逻辑上会更规整一点。
第三，它有分组止盈和动态平仓。既可以整体达到目标后统一出场，也可以根据盈利情况分批处理，行情稍微回撤时，能先锁一部分利润。
第四，它限制了最大订单数量和最大持仓手数，不会无限制加仓，至少从代码层面给仓位设了一道边界。
但缺点也必须讲清楚。
它默认的均线周期非常长，信号会比较滞后，适合看大方向，不适合短线频繁切换。一旦行情突然反转，均线很可能反应不过来。
另外，它本质上还是网格马丁。只要遇到趋势反转后的深度回调，同方向仓位越堆越多，浮亏压力还是会很大。
还有一个问题，它更偏向先处理盈利单，亏损单容易留下来，长期运行可能出现小赚不断、大亏难受的情况。
最关键的是，它没有硬止损逻辑。遇到极端行情、跳空或者黑天鹅，风险会非常大。
所以这类EA适合研究和回测，不建议直接重仓实盘跑。源码我放下面了，不会编译或者报错的朋友，可以来找侠哥拿。
