Quote:It appears that web-launched live gekkos get their data from web-launched market watchers. Does this mean the gekko would trade as if it were launched when the market watcher started?
So when you start a live trading in the UI you basically run 2 low level gekkos:
- the market watcher responsible for pulling market data and storing it in the DB
- a leecher that pulls this out of the DB
If you now start another gekko (paper trader for example) on the same market Gekko reuses the first watcher.
Quote:I'm asking because sometimes gekkos crash and need to be relaunched. Would the behavior be the same as if it hadn't stopped at all? (assuming, of course, that the bot wouldn't have made any trades during the downtime)
The answer on that question depends on which low level Gekko crashed. If the market watcher crashed it will crash the other one (so you don't have a live trader trying to pull new market data from a database that won't update).
Whichever the case: the proper solution is that when a leecher starts it doesn't simply check whether a current market watcher is running and when it started (current behavior) - but actually looks into the database to see if we have more data (if you stop a market watcher after a week and start it again you should have good market data of a week).
