control. A good rule of thumb is to never risk more than 2 percent
of the capital in your trading account on any one trade. (Advanced
traders, see important note following this list.)
Market risk.Theinherentrisk of being in the market is called market
risk and we have absolutely no control over this type of risk. It includes
the entire gamut of risk possible when in the markets. Market risk may
cause your carefully calculatedtrade riskto be much larger than antic-
ipated. Market risk can be far greater thantrade risk. For this reason
it is best that you never trade with more than 10 percent of your net
worth. This type of risk encompasses catastrophic world events and
market crashes that create complete paralysis in the markets. Events
causing marketgapsin price against your trade are also considered to
be market risk.
Margin risk. This involves risk where you can lose more than the dol-
lar amount in your margined trading account. Because you are lever-
aged, you thenowethe brokerage firm money if the trade goes against
you.
Liquidity risk. If there are no buyers when you want to sell, you will
experience the inconvenience of liquidity risk. In addition to the incon-
venience, this type of risk can be costly when the price is going straight
down to zero and you are not able to get out, much like the experience
of Enron shareholders in 2001. Liquidity risk can be caused by or ag-
gravated by amarket riskevent.
Overnight risk. For day traders, overnight risk presents a concern
in that what can happen overnight, when the markets are closed, can
dramatically impact the value of their position. There is the potential to
have agap openat the opening bell where the price is miles away from
where it closed the day before. (See the sidebar “Rules of Engagement”
later in this chapter for determining how to hold trades overnight.) This
gap possibility can negatively impact your account value.
Volatility risk. A bumpy market may tend to stop you out of trades
repeatedly, creating significant drawdown. Volatility risk occurs when
your stop-loss exits are not in alignment with the market and are not
able to breathe with current price fluctuations.

IMPORTANT NOTE: For some advanced traders, it is beneficial to
risk more than 2 percent of their trading account. The amount these
traders risk must be carefully calculated depending on their proven
historical performance statistics. See Chapter 9 for the formulas to
determine if your payoff ratio and win ratio performance warrant a
higher risk than 2 percent.
