Day Trader Risk Management App: Size, Stops, and Daily Limits
You already know the one percent rule. The hard part is obeying it on the third red trade of the morning.

Day traders need speed. Risk tools must be one tap away, not buried in settings. If checking risk takes longer than placing the trade, you will skip it on volatile candles.
Core metrics to watch daily
- Risk dollars at stake on the next trade
- Realized plus open P&L versus daily stop
- Average loser versus average winner (R)
- Number of trades after hitting 50% of daily loss
Use the free position size and prop firm calculators on profitai.co for quick math. Use Profit AI to enforce them after the fact: set a daily loss limit, max loss per trade, and max trades per day as playbook rules, and every trade and day is graded against them once trades are synced or imported. Before the trade, its analysis gives you an invalidation level and reward-to-risk to size from.
