Problem
Go here: Get an Open Position?
Put in your keys and BTCUSD as the symbol (capitalization matters, no slash between BTC and USD).
JSON response:
{
"code": 40410000,
"message": "symbol not found: BTCUSD"
}
Why? Because at 4:35:04am ET (+0/-5 seconds) on 5 Nov. 2025, for some reason all of my crypto positions in my paper trading account disappeared! That’s the problem!
I detected it because I have a data logger that’s been running for months and this morning it failed saying all of a sudden I have no open positions in BTCUSD, even though I’ve had that position open in my paper account for months, and the datalogger had been successfully running for months and does not make any trades.
Exceptions caught in Python:
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://paper-api.alpaca.markets/v2/positions/BTCUSD
…
alpaca.common.exceptions.APIError: {"code":40410000,"message":"position does not exist"}
Fix
I manually bought $100 back into the BTC/USD position at alpaca.markets, and now it works again since that again gave me an open position in it. But, why did my open crypto positions disappear this morning in the first place!?
