Can I run multiple strategies on the same trading account?

Technically, yes — you can run more than one strategy on the same account. In practice, it is not recommended. Different strategies have different entry logics, and on the same account they can take positions that work against each other.

Why this is a problem on cash accounts

Running multiple strategies on the same cash account unnecessarily increases your risk:

• Winning positions can be closed prematurely when one strategy's exit triggers while another would have continued holding.
• Exposure on losing positions can be amplified when a second strategy adds in the same direction at the wrong moment.
• The opposite can also happen — a winning position might end up larger than intended — but the upside is occasional, while the downside is structural. Overall, the risk is significant and the exposure is rarely worth it.

Why this is a bigger problem on prop firm accounts

Everything above still applies, plus prop-firm-specific risks:

• Hedging. Two strategies running on the same prop account can end up holding opposing positions on correlated instruments at the same time. Hedging is a violation rule on the vast majority of prop firms — if not all of them — and a violation typically results in the loss of the account.
• Contract size and overleveraging. Two strategies sizing positions independently on the same account can push total contract count above what's safe for the account's drawdown rules, leading to forced liquidation or rule violations.

For prop clients, the safest assumption is: one strategy per account at a time.

What's a healthy approach

• One strategy per account per day is the default recommendation.
• Rotating strategies by day of the week (different strategy on different days, on the same account) can be a sound approach and may improve edge over time. This rotation should be:
• Driven by guidance from the Vector team for your setup, OR
• Supported by proven data from tests the client runs at their own discretion (for hands-on clients comfortable doing their own analysis)
