I recently discussed this topic here:
I have since become even more frustrated with IB, if such a thing is possible. So I have been exploring Tradier. IB may be fine if you have a single straight forward brokerage account. I recently discovered that Tradier uses various types of limit orders that might be a good replacement for IB’s trading algos (see attachment). The Midpoint NBBO limit looks promising.
I’m experimenting with it now. I’ll know more in a week two. If it pans out, I’ll probably move several, if not all, my accounts to Tradier.
As a side note, If you do a lot of Options, the Tradier / Trader Oasis combo is definitely the way to go.
