SIA: 一直有人Buy Up @ 18.9，但是时不时有人Sell Down @ 18.8，但是卖出的量总是1k，我知道SIA贵，但是每次都是这样，应该是机构在制造什么？请帮忙解释一下

King Wan： 恰恰相反，一直有人Sell Down @ 0.24，但是每次到了0.24就有人buy up @ 0.245，这又是为什么？

我个人的猜测，SIA那个是庄家要吃货，所以就以小单压低价钱，避免拉升太快，而King Wan则可能是庄家在出货，造成涨价的假象，不过这种手段是不是太明显了？

望高人指点，哪位都行，最好昌昊大哥、北老、豹哥、牛王、xiaohu、banban等一众高手能给答疑解惑一下。

谢谢了先！

大家踊跃发言啊
