Very possible, but with zero commission there will be a spike of day trading until they shift their fee structures. Day traders, multi day traders, week traders, multi week traders, month traders, multi month traders....it's all trading at the end of the "day"! LOL
I often wonder what "long term" traders do when their stock spikes huge in one day based on an substantial news event.... Do they still hold according to their trading time frame...?
The stock market is an predator / prey scenario where the Companies and their lenders are the predators and retail IS the prey. Play wisely!
