This makes trading with small accounts difficult. Another element of risk is the market you trade. Some markets are more volatile and more risky than others. Some markets are comparatively tame. Some markets, such as currencies, have a greater chance of overnight gaps which increases risk.
Some markets have lower liquidity and poorer fills which increases risk.
Don't feel you have to trade any market that might make a move. Emphasize risk control over achieving big profits. The commodity markets are notorious for making locked-limit moves where the trader is stuck in his losing position. The market can go against him for days while he must helplessly watch his capital disappearing. This is certainly a reality, but the trader is not helpless to decrease the risk of it happening to him.
