Does your strategy survive the costs?

Spread, commission and swap are the strategy killers nobody models. A system that wins 60% of the time with 5-pip targets can be deeply negative after costs, while the raw backtest looks great.

How do you account for costs?

• the cost assumptions in your testing
• how costs changed a strategy you liked
• the pair or time frame where costs dominate

The trading costs guide gives the real cost model.
