The average daily move of the S&P 500, up or down, is 1%.
Same thing for the 7 major currency pairs (futures and Forex).
By contrast, some Nasdaq stocks routinely move 10% or more… in a single day!
But that’s not even the issue : Even if the leverage set by your broker is 1000 to 1, you can always limit your stop to any fixed percentage you like, like 2%.
There are no “risky” markets, only lousy traders with no money management skills.
