Lean VS Alpaca-API

6.) You cant maximize position size of spread options strategies, LEAN always assumes naked margin first and ON THE NEXT DATA FRAME - you get your reg-t margin for spreads. https://github.com/QuantConnect/Lean/issues/5693 We're running into 2 years of this issue being reported.

Thanks. I will check it out. Can you point me to the right part of the codebase I should be looking at? I know it must be somewhere here - https://github.com/QuantConnect/Lean

They have nice documentation on their website for how to download/import external data, though. They even have GitHub examples that pull data from Dropbox.

Here is an example https://github.com/QuantConnect/Lean/blob/master/Algorithm.Python/DropboxUniverseSelectionAlgorithm.py

There's also the open-source lean.io stuff by QuantConnect which looks decent and comes with data. It's pretty inexpensive too.

I can plot OHCL lines, I can plot OHCL scatter points on the chart, why can't I plot candles? It's just those scatter points put together. This thing has been going on for 8 YEARS.

Here's a link to one of the strategy examples from the QC team that does this -- loading a universe from an external source. https://github.com/QuantConnect/Lean/blob/master/Algorithm.Python/DropboxCoarseFineAlgorithm.py

Is there anyone using Alpaca for long term and passive investing? I am neither a US nor Europe residence, so it is pretty hard to find a decent broker. I came across alpaca.market https://alpaca.markets/ and noticed that there is zero comission for buying and selling stocks. I know that it has pretty good API especially for developers and day traders, but i am particularly interested in long term passive investing, and not interesting in day trading at all. Is it goog for long term passive investing (buying and holding etfs)?

No worries at all! https://alpaca.markets/ is another route for market data. Real time data is cheaper but it is lacking technical analysis. We used to use it and it's pretty good.

Access to historical data from Alpaca and Yahoo Finance, or from your own data provider.

I have been looking at https://alpaca.markets/ and wanted to use it to test out some of my API based trading.

What guarantees or structures are in place to make sure it doesn't end up like FTX?

Market data is an easier one to answer. We currently use https://alpaca.markets/ and they're pretty good, but we're also looking at https://polygon.io/ as they're the industry leader (but also 2k per month for what we require).

I'm trying to make an HTTPS request with an ESP32 to this website alpaca.markets. I have the CA cert and I'm using WiFiClientSecure.h. Here's my code, main.cpp is underneath all that.

Or you can sign up for a free account at Alpaca and use their historical data API. Then you can get data on many tickers with one function call.
