nasdaq 100 futures filled with huge sell market orders

on friday there was a big selling subject on e-mini nasdaq 100 which is clearly visible from the attached chart. 

nasdaq was undervalued compared to other three us indexes, which is always a good constellation for building a bigger position into the short side. the selling subject used active market orders that were really big (up to 200 sell market size) in the frequency of a couple of tens of seconds.

that means it was not really a high-frequency short term algorithm, but rather a fond or a bank that holds a position for a longer period of time.

thus, both their risk and their reward tend to much further from what i use in my intraday trading and it is not always clever to track it

that is why i can without any problems take a long and go against the big selling subject because the rotation i speculate on, is - compared to their risk/reward - really small.

this was one trade with a clear timing entry base on exhaustion of (retail) sellers.
