Our stock club has worked with several brokerage firms
including TDAmeritrade. We have not seen any irregularities
with TDAmeritrade accounting principles in fact it actually
reported two companies return of capital in a manner that
was easier to understand than Bivio (i.e. Crestwood Equity
Partners). I am not sure how large your stock club is but
TDAmeritrade will give you $7 trades if you ask. Our club
usually brings in $5000 to $7500 per meeting for trades. We
deposit all of the funds in our local bank and then do an
ACH to the brokerage firm and there is never a missing
deposit. There is no cost for ACH transfers.
