What is the worst one day loss you ever had?

I agree, more than 5% is too much.

It depends on capital in your trading account and risk level of your trades. For example sometimes I use 100-200 USD with Hotforex to trade exclusively on news. I take credit bonus and high leverage and trade on fixed spread account to avoid additional costs if spreads widen. Sometimes I can make 10X sometimes 3x, the biggest problem is to stop.
