With deepdiscount trading, it is 1.66 * 2 + 0.15 * 2 = $3.62 for using Sierra Chart, ignoring the $20 monthly fee. This is the same as Velocity's old price. It went from $3.62 to $3.75 and now to $3.88. Actually, it seems like the price never were at $3.75. It went from $3.62 to $3.88 More than the price increase, I find the behavior, well, disturbing. Hey, they are almost making IB competitive! My average per contract profit is not so low that it would be impacted by this to any significant degree, but this is starting to raise questions about how they handle communications with clients, changing practices about not cutting checks etc. Like I said, their competition is now IB, and they better have to chops to compete over product offerings, client money security and a litany of other things. Anyways, checking out a few other brokers feeds are in order, methinks?
