Costs
The spread is the market’s own bid and ask in the tick data. Commission and slippage are modelled per symbol with the rates below, and swap is the broker’s quoted rate, charged for every night a position was held across the whole window. The cost-stress runs multiply commission, slippage and swap by 1.5× and 2×.
| Symbol | Spread | Commission / lot | Slippage | Swap long | Swap short | Contract |
|---|---|---|---|---|---|---|
| GBPUSD | real bid/ask, every tick | $3.5 | 4 points | −2.1 pts | −0.5 pts | 100000 |
| AUDUSD | real bid/ask, every tick | $3.5 | 4 points | 0 pts | −1.9 pts | 100000 |
Negative swap is a charge for holding overnight. The cost-stress runs multiply commission, slippage and swap charges; the spread is always the market's own.
