The key components of a successful trading plan are an edge, discipline, risk control, and money management.
Controlling your risk
Successful speculation is all about managing risk. A winning trader always knows how much they will lose, but rarely know how much they will make. The key is to never let a single trade or single event (that may impact on multiple positions) have a major negative impact on the trading account.
"Never, ever, trade without a stop-loss order. If you don't know what a stop-loss is, you should not be trading."
Money management
A basic investment tenet states there is a direct relationship between risk and return. Trading is no different - the greater the account value risked on a single trade idea, the more volatile the total returns from the trading strategy will be.
A simple strategy is to never risk more than 2% of your trading account on a trade. Most professional money managers will risk a fraction of 1% on a single trade.
"There are many bold traders, but there are very few old, bold traders".
The Difference between the professionals and the novices.
The "Professionals" fit the following profile:
they trade completely objectively using mathematical models to arrive at trading decisions, there is no emotion involved;
their ideas are well researched to ensure their strategy has a definable edge;
they follow trends in prices, by controlling their risk and allowing profits to accumulate;
they realise the market is not predictable, so employ techniques that will profit by recognising trends, rather than anticipating them.
The "novices" fit the following profile:
their trade strategies are usually based on esoteric analytical techniques that are highly subjective, making it difficult (if not impossible) to determine the provision of an edge;
they have a pre-occupation with forecasting prices or dates on which trends in the markets will reverse (ie a belief that the markets are predictable);
by design, their subjective strategies make a disciplined trading approach difficult as it is too easy to "bend the rules";
they pay little attention to risk control and money management.
One final quote:
"Winners hold their winning trades, losers hold their losing trades"
