Did some reading and they also make money on all the "cash on sidelines" All day traders by definition are in cash 2/3s of each day and 2 days on WE. $25000 minimum also to be able to DT more than 3 trades a week. Margin interest is a biggie. Then depending on brokerage, they try to get you hooked up with an for fee advisor. This all makes sense of course and I kind of knew this already but didnt know to what extent. Swhab says it will only effect 4-5% of thier revenue. But TDA over 25%.
I just wonder at some point, all the free stuff we get might start costing unless acct balance is certain size.
I initially was concerned about TDA but less so now.
