Anyone interested in robo-investing might also be interested in Quantopian (
https://www.quantopian.com/).
It's marketed as a platform that facilitates competition for the best trading algorithms but really, algos can be as complex or as simple as you want. A simple monthly portfolio rebalancer takes ~5 lines of code (handle_data is boilerplate required by the platform):
def initialize(context):
schedule_function(rebalance, date_rule=date_rules.month_end())
def rebalance(context, data):
order_target_percent(symbol('IVV'), .6)
order_target_percent(symbol('MUB'), .4)
def handle_data(context, data):
pass
Plug that in, backtest it (it has a pretty comprehensive backtesting and research suite) and add your Interactive Brokers or Robinhood account details and you're off.
It's all free as well.
Note: I have no ties to Quantopian, I just discovered them after being disappointed by how little flexibility Wealthfront and Betterment offered me.
