I promised to get back to you on the verdict on the commissions. Right now I am paying $3.50 per contract for each trade, i.e. $7.00 for a roundabout, in and out. It's a hefty price to pay when you trade small, like me. About 34% of my profits are going to the broker.
So, on your advice (see previous comments), I called TOS this morning to plea my case. Alas, if they take me off this "flat" $3.50, they would move me to another type
of commission structure which would reduce the commissions to $2.25 each trade BUT invoke another kind of fee of $1.47 which would total $3.72 and not do me any good.
When I mentioned that "others" only paid $5.00 for a round trip, he responded by saying, "yeah, but they probably traded 1000 contracts a month."
He did say that when I got up to 200 trades per month, I should call back because they might be able to do something then.
And btw, he was looking specifically at oil (for me). I don't trade other futures. So not sure if the fee structure is different for other commodities. You'll
have to call yourself, if you're curious.
