While it isn't quite advanced as TD Ameritrade or E*TRADE, this online trading platform has plenty of features. TS's web platform is good, but its desktop platform is even better, offering many advanced trading features. We do feel that TD Ameritrade is a solid platform overall, but some also like Webull, especially those looking for a good Robinhood alternative. If you are serious trade and want to trade for a living, a platform like Interactive Brokers or TradeStation will work best.

Webull is an investing app and trading platform with commission-free trading on a variety of asset types. If you select a margin account, you will automatically have access to margin trading if your account is approved. Webull compares favorably to Robinhood here, as Robinhood requires a Robinhood Gold subscription ($5/month) to trade on margin. Lastly, TD Ameritrade is a great platform for day trading, while Webull is best for swing trading and semi-active trading.

Betterment is a robo-advisor with no minimum investment and no minimum account balance. If you want to speak with a Betterment financial advisor but aren't a Premium customer, you can book a 45-minute call for $199.As mentioned, the only other fee for Betterment are the expense ratios on funds. That's true not only because of the those with $100k invested gain access to the Risk Parity portfolio, but they also gain access to stock-level tax-loss harvesting. The only feature Betterment relegates to the $100,000 investment level is CFP access, but anyone can book a one-time call with a financial advisor for a flat fee.

Some charge a flat monthly or annual fee; others charge a percentage of AUM.Plus, those that charge flat annual fees have three different pricing tiers, making it virtually impossible to give you one answer for all situations. In such a case, the fees for the flat-fee robo-advisors as a percentage of AUM are:I've mentioned before that these robo-advisors with flat fees are always cheaper for larger portfolios. To arrive at the 0.28% number at the top of this section, I used the percentages for the flat-fee advisors just above, then averaged them with the other expense ratios in the table. The average management fee is 0.28%, and the average expense ratio is 0.09%.Over the course of 30 years and using our scenario above, that would add up to just over $34,000.
