Objections

  • Data lags about 4 days, making it less useful for current status.

    From 2 comments
    • The data being ~4 days delayed does kind of make this less useful. It is a nice concept and cool to see the historical data though. Just think the domain and the large "NO"…

    • This is a nice overview, but please remove the PolyMarket indicator. It is an obscene prediction mechanism as it creates horrible financial incentives to a war situation. Its…

Requests

  • Add live ship tracking data or an API key sponsor.

    • So if it's under 25% of the prior year's crossing it goes to NO, otherwise it's counted as open. The update cadence kinda sucks because I didn't spring for the $200 a month live…

    • I think I was just spit-balling what would be possible, rather than what I intend to do. As mentioned elsewhere I'm hoping to get an API key from one the data providers, I even…

  • Show ship movements for the Red Sea too.

    From 1 comment
    • Is it also possible to show similar movements for ships in the Red Sea, and make the types of ships colour coded?

Questions

  • Where does the crossing data come from?

    From 1 comment
  • What is the threshold function and update cadence?

    From 1 comment
    • Very cool, thanks for sharing! What's the threshold function? Do you have graduating `No --> Partially --> Mostly --> Open`? Also what's the update cadence?

    • This site has a lot of detailed data -- not sure what their sources are: https://insights.windward.ai Number of ship crossings is definitely trending upward as of today.
