With the same stop-loss level, why does one person lose only 1% while another loses 30%?
A common position-sizing formula: position notional value ≈ total capital × risk per trade ÷ stop-loss distance.
Key point: If you hold multiple positions in highly correlated contracts in the same direction at the same time, their risks add up, so your total position size should also be capped.

When prices are highly volatile, avoid adding to your position. Wait for prices to stabilize before reassessing.
