The biggest mistake is letting the trade count explode and skipping your stop‑loss. When you overtrade you dilute your edge, increase commission/fees and make it far easier to hit a prop‑firm’s daily loss limit or consistency rule. Always: - Set a stop‑loss before you enter and treat it as non‑negotiable. If the market moves against you, exit immediately – this protects your account equity and keeps drawdown within the firm’s limits. - Limit the number of open positions to a level that matches your risk‑per‑trade (commonly 1‑2% of your account). This prevents the cascade effect where one bad move wipes out several trades. - Use a solid position‑sizing formula (e.g., Kelly or fixed‑fraction) so each trade risks the same % of capital, making your drawdown predictable. - Stick to a trading plan and avoid chasing the market after a loss; discipline is key for firms like The5ers, FundedNext or My Funded Futures, which enforce daily loss caps and consistency rules.

By respecting stops and keeping trade frequency in check you’ll stay within the firm’s risk parameters and give your strategy a fair chance to work. How do you manage stop‑losses and position size in your prop‑firm account?
