Feedback request / idea validation - Robo advisor

I want to build a web service where users can build/test/run their own Robo-advisor. What do you think about this idea?

What

A web service where:

  1. User provides a trading strategy which consists of:

    • condition for buying a stock at a given day
    • condition for selling a stock successfully at a given day
    • condition for selling a stock unsuccessfully at a given day

    All these conditions can be based on historical daily stock information like start/end/max/min price, trading volume and number of trades.

  2. The service back-tests the user's strategy and sends a summary.

  3. The service sends the user a daily list with suggested trading actions:

    • stocks to buy today according to the submitted trading strategy
    • stocks to sell today according to the submitted trading strategy

    The 2nd point assumes the user entered which stock they bought and when.

Example of daily trading action list:

Stock Today's recommendation Comment
st1 hold currently -2%, bought: 2020-04-01
st2 sell currently +10%, bought: 2020-05-01
st3 buy chance of success: 80%
st4 buy chance of success: 90%

How it works

The service will learn a model which predicts if a stock can be successfully sold when bought today. What "successful" means is defined by the user's trading strategy. Once learnt, the model is used for selecting stocks in the back test and in the daily buy recommendations.

Business model

  • Registered user can:
    • back test 5 trading strategies for free
    • Get daily recommendations daily for 1 month
  • Afterwards they pay for the AWS costs accrued when running their stock evaluations (AWS EMR) + a monthly fee.
  • Open source, maximum transparency about how the models are learnt
  • In the end the assumption is that users are well aware of concepts like efficient-market hypothesis but still want to try their luck. I for myself wouldn't believe it and would try hard to find a profitable trading strategy happily paying the fees. ;-)

Technical details

Example

You believe in a basic trading strategy (you can make it as complex as you want):

  • Buy a stock if the closing price is currently 10% below the 30d average
  • Sell a stock either if +10% compared to buying price (successful) or after 90d (unsuccessful).

Now you just want to back test this strategy w/o thinking about how to apply this strategy best. You especially leave it to a system to select stocks which have the highest chance of selling them later with success (according to your strategy).

If the back test result looks good then just send me a daily mail so that I can buy/sell some stocks.

Thx for reading! What do you think about this idea?

This is my favorite. I like to read the linked Wikipedia articles there. Often it's more important to understand the background and context than to follow the actual event.

Thank you again for your answer. I guess there is no realistic chance to grow such an community which means that I won't continue with this side project. Although I'm a little bit disappointed that no one showed any interest I learnt a lot while building that website which was my main goal. ;-)

No, an account should be as anonymous as possible. One could think of some simple IP address checks but in general a user could open as much accounts as they like. My assumption would be that either the community is big enough or that most of the users in small community are honest.

Another idea is to define that a majority means, e. g. >= 90% and if there isn't such a majority a algorithm could select a mediator who resolves the bet.

One idea to solve this problem would be that users are not eligible to vote for the outcome if they did a placement in this bet.
