I’m new to the platform was wondering if it could link to an external API to fetch data.

I have a Piotroski strategy here [https://investorsedge.net/Strategy/Definition/24430/23672](https://investorsedge.net/Strategy/Definition/24430/23672) that I would like to explore setting up on Collective2.

InvestorsEdge has an API/JSON which allows access to the ranking tables on a given day, so I’d like to be able to access the API, receive and parse the JSON ranking list and trade the top 10 or so.
