Hello, I try to use USDC for all buying and selling operations but when I’ve bought a pair like BTC/USDC, the position obtained is BTC/USD and I really don’t understand why this behaviour.
I have USD/USDC pair but XTZ and BTC are in “/USD”:
| USDCUSD Crypto | $0.9998 | 43,539.964193187 | $43,529.08 | -$695.73 | |
|---|---|---|---|---|---|
| BTCUSD Crypto | $90,515.58 | 0.015238079 | $1,379.28 | -$4.97 | |
| XTZUSD Crypto | $0.5684 | 2,419.780772136 | $1,375.48 | -$27.65 |
The order seems to have been correctly asked and filled :
I’ve look at the details:

But as you see above, it was bought in USD.
And when I ask https://paper-api.alpaca.markets/v2/positions:
