DislikedOFT's edge will never fully "expire", even if the entire world was trading based off of orders. There's so much orderflow information to process, so many different agendas, so many different motives, that it will forever stay in motion. For instance, take a look at option barriers. Everyone and their mom plays those these days, and they still provide the same edge they did a few years ago when they were unheard of.Ignored
You mentioned that you use the DOM a lot in your trading and that you trade on a very short timeframe, right? How do you read the markets with all the short-term "noise" that is produced? Is there anything specific how you filter your trades?
Thanks
