Questions

Hey. First of all, thanks for a great library :)

I'm going to experiment with it, but before want to ask some questions

• Are you use it in production?
• Are there any possibilities for backtesting?
• How is it handles rate limiting?
• Any plans for Dead men's switch functionality or is it possible to implement is as an advisor?

Best,
Ihor

Hey @rupurt.
I'm using tai for data mining and recently I was faced with an error.
Any clues?

Manage orders in separate process to caller

Currently orders are managed by the caller process. This has the limitation that orders cannot be updated once that process is terminated.

For example:

When an advisor cancels an order in the on_terminate callback
Then the order should be sent to the venue and updated within the OrderStore
But the async task terminates early and never sends the order to the venue

Add paging to `orders` command

iex -S mix hangs on 'generate tai app'

hi,
It seems that the quickstart you have in your readme doesnt work as intended; it seems like the app hangs indefinitely, I never get the interactive shell back.

please let me know if there anything Ive missed or if theres any other information you would like.

Seperation of Database from main tai package.

Is your feature request related to a problem? Please describe.
I think there might be a case where a user of Tai would want to use for other tooling, such as analytics of order books or volatility. Therefore the OrderRepo might not be necessary and it might be an additional piece that can be plugged in. What do you think?

Really love the work done here. If i find some time i'll be willing to contribute.

Add adapters to `OrderStore` & use etso by default

Getting up and running

I'm trying to get this running. Do I need to register + provide API details for each exchange, or can I stream the public information using the dummy abc123 keys?

Using the dev.exs example:

** (Mix) Could not start application tai: exited in: Tai.start(:normal, [])
    ** (EXIT) an exception was raised:
        ** (ArgumentError) can't fetch value for key `:api_secret` of application `:ex_poloniex`, can not resolve key POLONIEX_API_SECRET value via adapter Elixir.Confex.Adapters.FileFromSystemEnvironment
            (confex) lib/confex.ex:245: Confex.resolve_and_update_env/2
            (elixir) lib/enum.ex:1336: Enum."-map/2-lists^map/1-0-"/2
            (tai) lib/tai.ex:8: Tai.start/2
            (kernel) application_master.erl:277: :application_master.start_it_old/4

I see the poloniex_api_key and poloniex_api_secret files in the /secrets folder, so I'm assuming that bit is all good.

Installation failed

Describe the bug

I'm new to Elixir and Tai.when I followed the installation instruction and ran mix setup , i got
** (Mix) The task "setup" could not be found.

To Reproduce
> mix new example
Then follow the instructions

Expected behavior
Maybe the Tai App? Still trying to understand.

Desktop (please complete the following information):

• OS: macOS12.6,Elixir 1.14,Erlang 25
• deps:
  {:tai, "~ > 0.0.75"},
  {:ecto_sqlite3, "~ > 0.7.1"},

Tai Config
don't know about it.

Easy way to ingest market data from a Provider?

Sorry for opening an issue for this, but I'm finding it hard to use this library without many examples.

How would I just ingest data from say, Deribit, using this library?
