What's a safe risk percentage to use?

Most traders stick to 1–2% of their account per trade. That way, even if you hit a rough patch with multiple losing trades, your account won't take a devastating hit. You can tweak it based on your comfort level, but going above 5% gets pretty risky.

Does this work for forex and stocks?

Yes, it's designed for both! For forex, it'll often calculate in lots or units based on pip value, and for stocks, it'll give you the number of shares. Just make sure your inputs match the market you're trading, and it'll handle the rest.
