is Unbundled stock commission better than Bundled stock commission in IB or is it matter in term of trading volume per month? thx
You have to work out the numbers based on the vehicle you trade. I trade futures and it is better unbundled. I suspect unbundled is better for most types of investments.
It depends upon the amount of volume you do, and for equities, it also depends upon whether you chiefly take liquidity or chiefly give liquidity.
