I'll give a specific example of why I don't like Fidelity as much.
I have an account with a bond fund in it and I have the monthly dividends automatically reinvested. Sometimes I want to see the transactions of those reinvestments with dollar amount, number of shares, date. Here is what that looks like for part of one transaction (date is a few lines above)
Why does it take so much display real estate to show this? I have to scroll to see all the transactions? Am I doing something wrong? This is not simplicity.
And I cannot get Activity for more than 90 days at a time at Fidelity. That sucks.
In contrast at TDAmeritrade, I get a fairly clean report of multiple transactions in less space than a single partial transaction at Fidelity:
And I can put in any custom date range that I want.
I also like that I can customize the columns and order of the columns in the Positions display at TDAmeritrade. Can one do that with Fidelity?
