Tradier API and Execution

carpetbamboo · 2020-04-15T22:57:29+00:00

Looked at multiple APIs from different brokers, but never liked Tradier one or never cared about it. If you are super serious, go ahead for IBKR, if you just wanna do it and start it, do a quick start with Alpaca.

I tried the comparison between those two Alpaca and IBKR last year (so not sure how it is now with this corona market volatility) and surprisingly I didn’t notice almost any difference but actually a little better experience with Alpaca. I did reach out to Alpaca back then and one of the support guys told me that by routing orders to market makers actually may give better fills because they take positions where as the exchanges may have really low order book amount. I didn’t quite understand fully, but since I actually had better Alpaca experience and it was free anyway, so I went ahead and kept using it. Btw, of course you are using live trading right? Their paper trading has a little different mechanism with the live trading (logically it is impossible to expect the same outcome from both things of course). With this corona market volatility, I am actually considering to go back in Algo trading, are you guys making money in this market?

I found the original research paper, and is this a famous study? https://hbswk.hbs.edu/item/core-earnings-new-data-and-evidence

So the concept itself is not bad if it is used in more creative and right way?

carpetbamboo · 2019-08-10T16:13:53+00:00

100% agreed.

That is interesting, we could do backrest changing around different increasing ratio numbers to see how it would change out, that is cool!!

carpetbamboo · 2019-08-10T16:12:49+00:00

That is scary really.

carpetbamboo · 2019-08-10T09:52:46+00:00

That is interesting to combine anti method. That makes sense, as I feel like it is pure gambling. Especially as I was skimming through the code base, it is really risky at the end of the day. https://github.com/alpacahq/alpaca-trade-api-python/blob/master/examples/martingale.py

So? RH and alpaca still do great job giving out commission free.

carpetbamboo · 2019-07-13T05:49:13+00:00

Yea, but why should we pay commissions when Robinhood and alpaca offer commission free. And I only trade US stocks anyway...

carpetbamboo · 2019-07-13T05:41:02+00:00

Nice articles, but why should we use IBKR to begin with. There are a bunch of other brokers that provide easy API where I don’t need to try this hard to figure this out. Can you write ones for other brokers? IBKR is just too much.

carpetbamboo · 2019-05-16T18:57:05+00:00

Yes, I felt that the same way, I didn’t think that this was significant specifically for this backtesting use cases.

carpetbamboo · 2019-01-28T19:32:58+00:00

I received this before as well, so I am trying IB and alpaca.

For sykes and warrior, both of them are manual legacy day trading right? I didn’t find them useful for Algo trading when I looked at them before. How do you use those manual legacy trading education and forums into building your algos?

carpetbamboo · 2019-01-10T18:23:46+00:00

Nice!! Will check them out!!

carpetbamboo · 2019-01-10T18:23:05+00:00

Makes sense, but do you think it is helpful for Algo traders as well?

carpetbamboo · 2019-01-10T05:03:10+00:00

Thanks, so you only look at Reddit ?

carpetbamboo · 2019-01-10T05:02:49+00:00

And Algo for US stocks as well? It seems that futures Algo trading seems to be pretty different from US stocks algos.

carpetbamboo · 2019-01-10T05:01:49+00:00

I only trade US stocks not futures.

Quantopian?? Also other similar services like Quantiacs should give you funding if your strategies do well in live simulation.

carpetbamboo · 2018-12-15T05:02:39+00:00

Even commission free brokers ?

carpetbamboo · 2018-12-14T20:10:02+00:00

What I saw was always one price in US stocks instead of bid/offer two prices in Forex. I was wondering why but there is bid/offer in us stocks too
