本周真是一个疯狂的一周，当周二收盘结束时，大盘趋于完美，众多股票出现非常好的 set up pattern ,好多人包括职业 traders 都多仓回家，可是周三一个30多点的低开简直不给人任何机会，不得不stop out 斩掉多仓，traders 开始反手做空，谁知道事情并不是那么容易，周四周五的两天上涨几乎又将周三的大跌收复。如果说周二是trap long 的话，那么周三又将short traped.
Not easy guys,Not easy...

People probably know Meriweather from former Solomon Brothers and Long-term capital. These are the chartists in their purist forms ...
Again, it is pretty difficult to figure out capital requirement of a barrel of oil in tar sand, the reason behind huge differentials between WTI and Bent oil price etc etc ... However, it takes a few minutes to look at the chart and be convinced the direction of the market.
And then direct capital based on that convincing piece of evidence...
