小弟之前是每四個月投入一次，一次也才 $900，持續了約五年
兩個月前寄客服希望調降手續費，也是回答了幾個問題
最後就降到 $4.95 了
不過客服問我的問題不太一樣，可能因為我沒有說要換另外一家
我是跟客服說雖然新的 ETF 很多，不過我還是想繼續買 Vanguard
其他家只要 $4.95 或 $2.95，雖然我量很少，還是希望可以調降
客服要我回答下列幾個問題
1. What rate are you looking for ?
2. Do you plan on consolidating any accounts with TD Ameritrade,
making any large deposits or any large withdraws ? If so,
approximately how much value do you plan on depositing or withdrawing ?
3. Do you plan on changing your trading activity in the future ?
If you are changing your trading stratedy, how many stock and/or option
trades do plan on trading in an average month ?
4. Do you plan on trading any index options ?
How many contracts per trade for your options trades on average ?
從回答完問題到成功調降大概過了十天，因為我不知道在哪看自己手續費多少
所以是等太久了再跟客服問後續情形，客服才回說已經成功調降
