High Speed Trading Problem


My software requires stocks to be bought and sold at high speeds. However, it crashes after about a minute of trading.

I am currently using the REST api to place orders, but I suspect that it can not handle the amount of order I am placing. Is there a more reliable way to place orders? Or do you know a way to fix my problem?

I appreciate any help you can give me!

There is a limit of 200 transactions/minute (see the docs here) If you are getting an error code 429 from any of your REST calls then that is the issue. You will need to meter your orders in that case.

One way to address the transaction rate limit is to use websocket for monitoring order status changes and use REST requests only when absolutely necessary
