This is about Trading! They see the order flows. I see nothing but think I do while guessing on TS/L2/charts. They shift their order like crazy without cost. I was forbidden or penalized to cancel my orders. They unify their sources and actions. I am alone and even blinded by their media partners. They arbitrage with no time and little cost. I have to wait or have high splipperage. They sit there got their order filled. My orders never get executed unless the market is moving against me. Conclusion: You will not be able to complete "they". Do not even try to join "they" as you won't be able to. Otherwise only your dirty broker will be happy.
