Is machine going to take over the whole trading world? What's the trend and limitation of algorithmic trading? Of the whole trading activity now, how much does machines account for?
Quote from Joe Doaks:
I can only speak to NQ, but if algos were dominating NQ trading I would expect to see size frequently traded. Instread what I see is about 95% of the trades being small lots, onesy-twosy-threesies. It is straightforward to capture the number of trades and the corresponding volume to verify this, or by eyeballing the tape. So if the peanut gallery is providing the liquidity, are they going to take away the peanuts?
Quote from masterm1ne:
Your thinking is one dimesional. Some algos send 1 contract orders at a time, then have a time delay till they send another. The purpose is of course to mask their size....

Quote from uexkuell:
Au contraire:
Small lots can be traded at high precision (pricewise) only by algos not by humans (too slow).
Big lots is indicative of true dinosaurs trading like pension funds (or sometimes an algo catching a chance).
