What Makes a Good Trading Strategy?

 
Ask most NEW traders, and they will tell you about some moving average or combination of indicators or a chart pattern that they use. This is, as the more experienced trader knows, an entry point and not a strategy.
Any trader who is more experienced will say a strategy should also include money management, risk control, perhaps stop losses and of course, an exit point. They might also say that you must let your profits run and cut your losses short. A well-read trader will also tell you that your strategy should fit with your trading personality.
BUT there is one other vital ingredient that many traders forget - and that is to fully understand the "personality" of what you trade. Some traders specialise in say, gold or Brent crude or currencies or they might specialise in a particular index such as the FTSE 100 or the Dow but many traders choose to trade shares. Indeed some traders dabble in a bit of everything. I think this is the area that causes many traders to fail or at least not reach their full potential.
In my view: You absolutely MUST specialise.
I am sure that on the surface most people would say that sounds sensible but here is why it is a MUST!
Superficially, many charts look the same. I bet if you had not seen the charts for some time and someone where to show you a chart of Brent Crude over 6 months and then a chart of Barclays PLC over the same 6 months you would be hard pushed to say which was which purely on the look of the chart.
However, I bet that if you found a trader who trades ONLY Barclays day in and day out and also found someone who trades ONLY Brent Crude day in and day out, both of them would easily identify which was which. WHY?
Because every share, index or commodity has it's own "personality".
Some will be volatile intra-day, some will follow their sector or the main index (market followers), some will do their own thing, some will spike up and down regularly, some will stop at key moving averages and some will just plough through. Some will move by 5% on average before they retrace and some by 2%. Some will gap up or down regularly, some will not. You get the idea!
Therefore, no matter how good you are at analysing indicators, moving averages, trends and patterns, the same strategy WILL NOT work for everything. I would go so far as to say that a strategy that works well for Bovis Homes, for example, is likely NOT to work for BT Group - they have very different "personalities".
So let's return to our question: What makes a good trading strategy? Let me answer with a series of ten questions that you need to find answers to, in order to build a REALLY GOOD strategy.
  1. What do you want to trade (share, index, commodity, currency, etc)? If your answer is shares (plural) I would urge you to pick one typical share at this stage to really specialise. You can add more later.
  2. What "personality" does that share, index etc have?
  3. What entry system is the most reliable for that share?
  4. What stop loss system is the most effective for that share?
  5. What average risk will a typical trade carry?
  6. What exit system works well for that share?
  7. What is your trading personality (attitude to risk, losses, discipline, how much do you worry etc) and can you trade that strategy without overriding it?
  8. What timescale do you want to trade? (Using intra-day or end of day data)
  9. How much data do you keep on past trades to help identify strategy weaknesses?
  10. How does all this fit with your trading objectives?
Once you have an answer to each question you need to do one final thing. Make sure all those things fit together and complement each other. For example, if the ideal stop loss position represents a big average risk and conflicts with your own attitude to risk, you need to start again. If you will override your exit point because greed makes you hang in for more, you need to think again. Perhaps you shouldn't trade that stock in the first place - look for one with a different "personality" which will lead to a strategy you can trade comfortably.
It is a long and sometimes painful iterative journey. You might need to go round and round in ever decreasing circles over a long time. Testing and refining, testing and refining before you can truly have a reliable and repeatable strategy that REALLY WORKS for you.

Forex Trading Psychology -vs- Forex Trading Method

Did you ever see the movie The Italian Job, and if so do you remember when John Bridger asked: “You see those pillars over there, that’s where they used to string up thieves who felt fine.” Make the transition from paper trading to real money trading and you will feel FINE too – Freaked-out Insecure Neurotic and Emotional. And what a great analogy ‘string up’ is, because after all those months of paper trading winners are replaced with real money losses, that is exactly what you will feel like doing to yourself. The Trading Psychology Viewpoint No discussion about trading, or the consideration to begin trading, can be done without a harsh realization - the vast majority of all traders lose. It is said that the reason that most traders lose is because they are not psychologically prepared to trade, that is they are not prepared to accept financial risk for something of which they have no control over the outcome. Forex Trading is much more of a psychological problem then a methodologica...

Extreme TMA System

The market, like a pendulum, is a never ending sequence of extremes. It forever tries to reach the mean but never succeeds, constantly overshooting it´s mark, reversing and trying it again but always failing to reach balance. This system attempts to capture those extremes. It is a compendium of my understanding of the market, brought to it´s simplest expression. The principles are not complicated. The first indicator, the TMA shows us the average of the path that the price action in the market is following. As such, it is a backward looking indicator and attempts to determine the future from the recent history. It corrects itself by repainting itself. It has two outer bands that show us the outer boundaries of price movement that we are searching for. Our second indicator, the TMA Slope indicator will show us the relative change in the slope of TMA as compared to previous candles. It determines in which direction a trade must be placed and also shows divergences to price. For examp...

What's more important: Trading Method or Trading Psychology?

Ancient argument: What's determines success in trading: A successful methodology  Psychology and discipline?  Answer: BOTH! But this is not a "chicken or egg" dilemma. Clearly in this case method comes before mind. I don't care how much self-discipline you have. If you don't have a viable trading methodology, then you will lose money. So method is more important. Well, maybe "more important" isn't the right phrase to use. But it definitely comes first. The reason I say it may not be more important is because there are many valid trading methodologies available. Yet ironically, traders keep jumping from one method to another ... one indicator after another  one book after another  one mentor after another  one seminar after another  This is the infamous "search for the Holy Grail." Sorry ... doesn't exist. Like most things in life, people keep looking for the answer outside of themselves, w...
