Does anyone know of a stock/option trading firm that will let me have unlimited trading activity without having $25,000 at a rate reasonable or better to TD Ameritrade?
You can always trade non-retail (prop) remotely at a firm with no trade minimums. In other words, trade "prop" without using leverage if you don't want it, and pay commissions directly to the prop firm (probably in the 0.004/share range, keeping 100% profits of course. Be mindful of platform fees though, you'll find that most firms charge $250 or so per month.
I'm seriously considering this, or might switch to trading spot fx. What's a good remote prop that will let you open up an account with around $1,000?
