I Used to use PFG, Overall a great firm..... No complaints
Now I Use FFasttrade 3.32 per round trip, But they have 2 different platforms remote light and remote pro which both cost money to use...
The Pro is as close to TT as they could get it, much much better than the Best platform PFG offers for free. Great vertical scalping view! The down side is there is a software fee of $550 per month......I negotiated that down to $300 after 1 month, after trading about 1000 round trips.
The remote light gives similar to the executions to the Best. (Never traded the light live only paper) That one is $175 per month, I wouldn't recommend that one because it is java based, much slower than the citrx based pro.
So to compare ffast to PFG the commissions on 800rt at
PFG $12800
FFast $2656 + 550 software fee
That math is the exact reason I left PFG, and got better executions to boot.......
Good Luck
