Insufficient Balance

Under Paper trading account, I am getting this error trying to submit a sell market order on BTC.

market_order_data = MarketOrderRequest(
symbol=“BTC/USD”,
notional=25000,
side=OrderSide.SELL,
time_in_force=TimeInForce.GTC
)

market_order = trading_client.submit_order(
order_data=market_order_data
)

Error: {“available”:“0”,“balance”:“0”,“code”:40310000,“message”:“insufficient balance for BTC (requested: 0.495057308, available: 0)”,“symbol”:“USD”}

Update. Changed my order to “BUY” and was filled. Whats the problem with “sell”? I guess its looking for any long position to sell but Im trying to submit a short.

@biggerrisk You are correct. The original order was trying to sell BTC and you didn’t hold any BTC. Alpaca doesn’t support shorting crypto.
