Websocket streaming for tradier

[dodofarm]

I see that it's mentioned in tradier.py it's mentioned that websocket streaming isn't supported yet.

Do we have an ETA for that?

It is not currently on the roadmap. If you would like to build it then we offer our Pro Plan for free to anyone developing lumibot. Robert Grzesik 347-635-3416

I just briefly looked through the code. As far as I can see websockets aren't implemented at all yet.

So this would require to essentially also make significant changes to strategy.py since currently it's purely poll-based, am I correct here?

Once that is done connecting to the Tradier streaming API would be more or less simple.

I was under the impression that Alpaca uses websockets for trade notifications, and Tradier does as well. If you mean websockets for pricing data then I believe you are correct.

I've not tried it but the Interactive Brokers code appears to have streaming for price bars:

lumibot/lumibot/brokers/interactive_brokers.py

Line 1033 in 88d0b9e

def start_realtime_bars(

lumibot/lumibot/strategies/strategy.py

Line 3208 in 88d0b9e

def start_realtime_bars(self, asset, keep_bars=30):

Yes that’s true, it uses a mechanism where you run a function called something like start_realtime_bars() (could be misspelling it). However last I checked this was not working - and to be honest isn’t architected the best.

well I settled on using Tradier so I'll make sure to take a look at adding websocket streams to the bot.

Thanks for the inputs and will comment here or create a pr when needed.

[grzesir]

Ok awesome, just let me know when you’re ready. Btw did I mention that we give the pro plan for free to lumibot developers? Let me know if you plan to add some features to Lumibot and if you’re interested in the pro plan Robert Grzesik 347-635-3416
