No, every account does not need to have the exact same strategy. Diversifying your approaches across different accounts can help manage risk, especially when trading with prop firms. For example, using a trend-following setup on one account and a mean-reversion strategy on another can prevent all accounts from taking simultaneous drawdowns during choppy market conditions.
However, splitting your capital too thin across vastly different or untested strategies can hurt your consistency. When managing multiple evaluations or funded accounts, keeping track of daily loss limits, news restrictions, and consistency rules becomes much harder if every account trades a completely different playbook. Many traders prefer to master one core edge first before expanding.
How do you handle your setups across multiple accounts? Do you replicate trades or run completely different systems?
