πŸ›‘οΈ Scalper-Specific Protection

  1. Set a "Max Win Cap":

    • Never let a single trade exceed 5% of your daily target.

    • Example: Daily goal = $1,000 β†’ Max trade win = $50.

  2. Use Partial Closes:

    • Close 70% at 1:1 R/R β†’ 30% at 1:3 (splits one trade into two "wins").

  3. Avoid News Scalping:

    • High volatility can create outlier wins β†’ temporarily pause during high-impact events.


Why Scalpers LOVE This Rule

Traditional Prop Firms 🚫

TradersFlow βœ…

Ban scalping or limit trades/day

Unlimited scalping!

Force minimum trade times

Hold trades <3 mins allowed

Penalize high frequency

Encourages consistent small wins

πŸ• Think Like a Pizza:

  • Bad: One giant slice = 80% of pizza (like a big win)

  • Good: 20 small slices = each 5% (scalping perfection!)

  • Rule: No slice >40% β†’ Easy for scalpers!


βœ… Key Takeaways

  1. Scalping is CR-friendly by design (many small wins).

  2. Only risk: Occasional big wins – fix with extra trades.

  3. Trade freely: No limits on frequency or duration.


Example Safe Zone for $10K Account:

Max Safe Win/Trade = (Daily Profit Target Γ— 0.4) Γ· 10 e.g., Daily target = $1,000 β†’ Max win/trade = **$40**
