[Idea] Automated programmable re-distribution rules for funds

The idea is that have self-managing funds. Basically it would allow the fund manager to program certain rules that affect the asset composition of the fund. 

For example:

If the weekly moving average of Bitcoin falls below 8000 USD switch all allocated BTC of the fund to USDT.

If LINK gained more than 20% in the past week switch all allocated LINK of the fund to BTC

If the Bitcoin dominance crosses 70% switch all allocated assets into BTC

For the definition of each rule a certain price of GVT could be charged from the manager. Also it should be considered to charge an amount of GVT everytime a rule has been executed.

It could even be allowed for the manager to provide an URL that, when called returns true or false (or maybe even a json-structure with the new fund composition?). Like this technically inclined managers could program very complex rules without having to rely on the framework offered by the platform.

Example: 

If http://alex.com/gv/fund-risk returns true move all assets into USDT.

The investors should be able to see what rules were defined for the fund.
