Why Position Sizing Matters

Position sizing is the single most important aspect of risk management in forex trading. It determines how many lots you should trade based on how much you are willing to risk on a single trade.

The formula is straightforward: Lot Size = (Account Balance x Risk %) / (Stop Loss in Pips x Pip Value). This ensures that no single losing trade can significantly damage your account.

Most professional traders follow the 1-2% rule - never risking more than 1-2% of their account balance on any single trade. This means even a series of losing trades will not deplete the account beyond recovery.
