Create a cryptocurrency trading bot in Elixir

Hello,

I just added another episode about the topic mentioned above - this time it’s about building a naive trading strategy:

Let me know what you think,

Thanks in advance,

Kamil

Pretty interesting! I am starting work at a financial company and this could be extremely useful.

Thanks for the comment! I will try to push out those episodes quite frequently but I’m sure that very soon you will know much more about that stuff than me(if that isn’t the case already!)
In the next episode I would like to put much more “Elixir specific” content like introducing supervision tree etc - stay tunned, like and subscribe

Looks good! And til about that elixir socket library which looks fantastic. It’s not over engineered, I think it’s just right. I mean come on you wrote a crypto streaming app in 15 minutes… Try doing that in go! Lol

Hehe, I served my time in Go. From personal experience, it would be closer to a week than 15 minutes
Ignoring Go (as nobody cares) - thank you very much for your reply, I’m still testing a lot of things and comments like yours help a lot.
I was wondering did you watch both videos? I feel like the tone of them is really different and I wonder which like you like better?

Thanks in advance

I didn’t see the second one! So a few notes, I didn’t like the music LOL, and there was about 10% of the code style that I didn’t personally like. But overall I think it’s quite good, the only truly fatal flaw is that you shouldn’t Process.exit(self(), :finished). Anything besides :normal is considered to be an error code, when you start supervising, you might not get what you expect, and if you still want the exit message you should use Logger.info or something. Also, even better than Process.exit is to emit the result {:stop, reason, state_for_terminate_2} in place of {:noreply, state}

Just some clarification on this one - you didn’t like the music because it wasn’t type of music you like or it was annoying / distracting you?

I think your comment regards the Process.exit is on point. I didn’t put too much effort in this part as it will be refactored in 3rd video, but indeed I’ve could return {:stop, reason, state} - that’s much less confusing for people new to Elixir processes etc.

I think maybe it was not bad for a filler, but I dunno, i didn’t like it, though I don’t categorically hate that type of music. Pretty quickly it more or less faded away in terms of distraction, so this could have been a matter of personal taste.

Damn, this is some good content. Watched the first video, it’s great! I wrote a trading bot in ruby couple of years ago, will be fun to compare how you implement the trading strategies.

Thank you very much for your comment. It will take a few good videos before I will get to stop losses, retargeting and similar - also please keep in mind that this is an “naive” strategy. My aim is not to focus on strategy itself but on laying a matrix of states that servers can be in, how they work together etc. I picked up the trading bot as it’s complex enough to get to nice web of supervision tree, updated between videos - on the other hand it’s not too geeky / abstract to keep people engaged - I think it’s cool to understand few thousands (hopefully) lines of Elixir application (not related to web - just processes and their interactions)
