We are using python/lean to test some of our algos and Alpaca as a broker.
We are experiencing huge troubles with paper accounts in recent days.
- Wrong equity, buying power
we have open a fresh paper account with $1M (and $4M buying power), we made some trades yesterday (at peak our stock portfolio was worth 900k), and our equity was at 1.001M (+1k) at the end of the day with ~700k invested in stocks as we closed 4 position. Now, before market open equity suddenly jumped to 1.7M and our buying power was scaled back to $1M.
it happened also on Friday (Jan 29) and yesterday (Feb 1) - we decided then to reset equity and start from scratch, but we can’t do it all the time.
our paper account number is 3FE00C0E.
- no charges for short position
we also tried to just check how in practice you charge for short position. We shorted 100 NVDA on Jan 28 and bought it back next day - no charges was applied. Also it seems that no real margin interest is charged even if you use margin trading. Are those two costs not simulated on paper accounts?
Thank you in advance for any insights on paper accounts stability.
