## Execution Model
All pairs use Bid/Ask execution: longs open at the ask price and close at the bid; shorts open at the bid and close at the ask. The spread between bid and ask reflects underlying market liquidity.
**Dynamic spreads** are enabled for all crypto and stock pairs. On these pairs, trades execute at a Price-After-Impact that applies zero spread under balanced order flow and wider spreads when flow becomes one-sided. All other pairs (ETFs, commodities, indices, forex) use standard bid/ask execution.
***
## Holding Costs
All pairs incur rollover fees that accrue continuously per block. See [Fees](/traders/reference/fees) for formulas and worked examples.
| Asset Class | Holding Cost | Basis |
| --------------- | ------------ | ------------------------------------------------------ |
| **Stocks** | Rollover fee | SOFR + carry premium |
| **ETFs** | Rollover fee | SOFR + carry premium |
| **Commodities** | Rollover fee | Futures term structure + carry premium |
| **Indices** | Rollover fee | SOFR + carry premium |
| **Forex** | Rollover fee | Futures term structure + carry premium |
| **Crypto** | Rollover fee | Funding rates + futures term structure + carry premium |

## FAQ
No. Stocks trade Monday–Friday, 9:30 AM – 4:00 PM ET. Day trades (intraday positions with leverage above the overnight cap) auto-close at 3:45 PM ET. You can place limit and stop orders outside market hours; they queue and execute at market open. Crypto is 24/7; forex is 24/5.
Limit and stop orders queue until the market reopens and execute at the first available price. Market orders are rejected during closed hours. Note that prices can gap between close and open, so queued orders may fill at a different level than when placed.
Ostium regularly expands its market offerings. New pairs are announced in official channels and added to this page.
