In the paper account API, I keep getting orders rejected because day trading buying power is stuck at 0 even though I’m not actually doing day trading. This makes it impossible to use the API for testing long/short strategies.
Have you tried resetting your API keys?
If not, what are you trying to trade as well? Is it a specific asset or all assets in your universe? What order types are you using?
Yes I’ve done multiple API key resets, as well as increasing the starting amount of the account. The strategy I’m building uses only ETFs.
For instance, I might go long half a dozen ETFs on day 1. On day 5, two of them will increase position, and one might flip to short, but the API rejects them all because of 0 day trading buying power—even though there is more than enough overall buying power.
