Ten overriding principles

  
  Education
#  #  #  #  #  #  #  #  #  #
  1. Always live to fight another day
  2. Entries must have a statistical edge
  3. Patience and discipline
  4. Be a jellyfish (swim with the current)
  5. Trade only liquid securities
  6. Focus on trying to capture the middle 80% of a move
  7. Know your exit points when you open a position (and stick to them!)
  8. When in doubt, reduce position size by 50%
  9. Limit losses to 2% of total equity for any single trade
  10. Start each day with a clean financial and emotional slate

The above list is relatively generic, but it helped provide me with a framework for organizing how I would approach trading as a business, what strategies I should adopt, how those strategies should be executed, and ultimately defining what success should look like.

Trading rules are vitally important – as is knowing when they should be broken. Even more important, I believe, is the process that one goes through in order to arrive at these rules and to make sure that as new market situations unfold and new blind spots are revealed, the rules and guidelines are enhanced to maximize the opportunity for the trader to continue to grow and develop.

Trading Success

Great forecast“Trading success is a function of possessing a statistical edge in the market and being able to exploit this edge with regularity. Trading failure is most likely to occur when you trade subjective, untested methods that possess no valid edge or when you are incapable of consistently applying edges that are available. Improving your psychology as a trader by itself will not confer an objective edge. Developing or purchasing a valid trading system will not in and of itself make you a great trader. The development of trading methods and the development of yourself as a trader thus must proceed in concert. You are only as good as the methods you implement and your ability to implement the methods.”

STRATEGIES FOR SUCCESS

trading-rules

After a year or so of trading, I found that I had standardized on about 15 rules/guidelines that have changed only slightly since then.

As requested, here are ten overriding principles that have survived the past five
years, through bull and bear markets:
Always live to fight another day
Entries must have a statistical edge
Patience and discipline
Be a jellyfish (swim with the current)
Trade only liquid securities
Focus on trying to capture the middle 80% of a move
Know your exit points when you open a position (and stick to them!)
When in doubt, reduce position size by 50%
Limit losses to 2% of total equity for any single trade
Start each day with a clean financial and emotional slate
The above list is relatively generic, but it helped provide me with a framework for
organizing how I would approach trading as a business, what strategies I should
adopt, how those strategies should be executed, and ultimately defining what success
should look like.

Trading rules are vitally important – as is knowing when they should be broken. Even
more important, I believe, is the process that one goes through in order to arrive at
these rules and to make sure that as new market situations unfold and new blind
spots are revealed, the rules and guidelines are enhanced to maximize the
opportunity for the trader to continue to grow and develop.

  • Most of the time, markets are very close to efficient (in the academic sense of the word.) This means that most of the time, price movement is random and we have no reason, from a technical perspective, to be involved in those markets.
  • There are, however, repeatable patterns in prices. This is the good news; it means we can make money using technical tools to trade.
  • The biases and statistical edges provided by these patterns are very, very small. This is the bad news; it means that it is exceedingly difficult to make money trading. We must be able to identify those points where markets are something a little “less than random” and where there might be a statistical edge present, and then put on trades in very competitive markets.
  • Technical trading is nothing more than a statistical game. The parallels to gambling and other games of chance are very, very close. A technical trader simply identifies the patterns where an edge might be present, takes the correct position at the correct time, and manages the risk in the trade. This is, of course, a very simplified summary of the trading process, but it is useful to see things from this perspective. This is the essence of trading: find the pattern, put on the trade, manage the risk, and take profits.
  • Because all we are doing is playing the small edges as they occur in the markets, it is important to be utterly consistent in every aspect of our trading. Many markets have gotten harder (i.e. more efficient, more of the time) over the past decade and things that once worked no longer work. Iron discipline is a key component of successful trading. If you are not disciplined every time, every moment of your interaction with the market, do not say you are disciplined.
  • It is possible to trade effectively as a purely systematic trader or as a discretionary trader, but the more discretion is involved the more the trader himself is a key part of the trading process. It can be very difficult to sort out performance issues that are caused by markets, by natural statistical fluctuations, by the trading system not working, or by the trader himself. (more…)

These are some of those fundamental and undeniable truths, as I have come to understand them over the course of my trading career:

  • Most of the time, markets are very close to efficient (in the academic sense of the word.) This means that most of the time, price movement is random and we have no reason, from a technical perspective, to be involved in those markets.
  • There are, however, repeatable patterns in prices. This is the good news; it means we can make money using technical tools to trade.
  • The biases and statistical edges provided by these patterns are very, very small. This is the bad news; it means that it is exceedingly difficult to make money trading.
