Paper Trading

In Alpaca’s paper trading, orders aren’t routed to the real exchanges. Instead, the system simulates the order filling based on the real-time quotes.

Q - What is Paper Trading?

When you run your algorithm with the real-time market, there are many things that can happen that you may not see in backtesting. Orders may not be filled, prices may spike, or your network may get disconnected and retry may be needed. During the software development process, it is important to test your algorithm to catch these things in advance. AlpacaDB’s Paper Trading Platform provides a real-time simulation environment where you can test your algorithm so you can catch these issues in advance.

In paper trading, orders aren’t routed to the real exchanges. Instead, the system simulates the order filling based on the real-time quotes. It calculates the account balance and performance numbers with virtual money.

Please note that while Alpaca’s Paper Trading Platform makes best effort to simulate real market behavior, active markets can cause results to vary.

Minimum funds to use Polygon API? I swear I read this when I signed up, but now that I’m searching, all it says is “a funded account”

You should avoid using Alpaca’s Polygon data feed because it will stop working on Friday. But to answer your question, even $1 would give you access to it. That’s actually why we’re losing the free Polygon data feed. People were leeching off of it without actually using Alpaca to trade:

It has become more and more apparent in recent months that some users have abused this system. Opening an Alpaca account not to actively trade, but to receive free access to polygon.io data. This is neither a win for Alpaca or polygon.io.

Ok, that explains the 200/month historical data. I’ve got no problems doing that. I noticed the flat files were for sale too, but those appear to be for enterprise or 1 on 1 sales.
