I disagree with some of the points stated above. However, I agree fully on the position sizing. I think that is one critical point to be a successful technical trader.

A very well written article, Chris. Thanks for summing up what I want to say.

Hi Chris,

Sorry I was in a rush yesterday and so I did not add much comment on this article, except that I think it is very well written.

Now, in terms of success rate as a whole, I personally do not fancy “high probability” systems. So, what is “high probability” in actual trading scenario? To me, based on the piles of backtesting that I have done, the statistics leading to such conclusion can actually be represented rather ficticiously.

What this means is that suppose you have a system that has a 10pips take-profit but a 40 pips-stoploss, and so if the market happens to be in your way, the statistics representing the performance of your system would most probably look wonderful, with nice equity curves and stats showing a success rate of 70% or above. But, be very cautious about these figures because it is probably less probable, but not impossible that you could still be showing some nice numbers, a dime short of great, on the statistics but did badly in actual trading performance. I have seen this in a lot of (automated) systems with emphasis on “protective” strategies such as trailing stops, partial take profit, and also scalping systems. These are usually “high probability” systems showing more wins than losses but could not stand the test of time. Again, I don’t want to generalize, and this is merely a personal opinion, and what that I have repeatedly been observing so far.

On the other hand, if we were to shift our attention to “low probability systems”, say, with hit rates hardly exceeding 30%, it could form a first impression that the system is not profitable. However, this could be misconception considering the following scenario:

Suppose if we have a trading system that say, has a stop-loss of 20 pips but a take-profit potential of say, 100pips, and lets say that we have an average win rate of 30%, so one can easy make it out by looking at the figures that it would take 5 losses in a row to wipe out the profit for every single win. Given that the win rate is 30%, this translates to a higher profiting potential on average.

Naturally, the above scenario is hypothetical and may not be applicable in real life due to the averaging assumption that excludes of plays down the effect of sudden rare “black swan” events. In real life, the mathematics behind win-loss are not as simple as what that is presented above because we often have what we call “streaks” of wins and “streaks” of losses every now and then.

The bottomline of a good trading system, in my personal opinion, is one that is be able to survive the randomness presented by the market in the most unbiased manner, and hence it is important to examine the “fusion” between a trading system against long stretch of historical data. Even that, past record is no gaurantee of future performance. I have seen trading systems that does well based on three over years of historical testing, but when the system is brought to live, it barely survive into the next 6 months! Well, I would not fault the system developer for developing such a system because what he had seen over the last three years in history shows that the system could possibly survive, on hindsight that is. Such is a mistake that is usually made, even by the most experienced system developer… the sin of bias that the system could survive on average, without taking into account the effects of black swan events, rare but suddent events, that could wipe out a traders account, often in a matter of moments.

Right… I need to stop writing now or else I may start to neglect the rest of my day. It has been a great sharing of thoughts!

Adieus!
Max

I certainly disagree that indicators do not work. Different currencies have different behaviour and you cannot use a single indicators for all curencies.

Try this:
Use only Stochastic and Willams for AUDUSD
Use only Stochastic and MACD for EURUSD

Trade only when both indicators signal the same direction for time frame 1 hourly and 4 hourly. Apply the basics of technical analysis as well: Identify prominent resistance and support levels

Example: sell AUDUSD only when Stochastic and Williams signal sell on 1 hourly and 4 hourly. With prominent resistance above it.

Give it a try. You may see a higher success rate.

To prove my point: Using EURUSD as a real life example.
Both Stochastic and MACD have signal SELL when EURUSD is trading at 1.3300.
Chart: http://tradingeducationprogram.org/2009/04/30/eurusd-has-room-to-fall/
Now EURUSD is trading at 1.3229, price has come down 71 pips.
Indicators do work but you must know use indicator for which currencies.

This afternoon, opportunity comes again for EURUSD. Both MACD and Stochastic have signal sell. I had entered a short trade 1.3350. See how it goes…

Earlier I mentioned that there is shorting opportunity for EURUSD at 1.3350. I had executed this trade and closed my position at 1.3267 for 83 pips profit.
See: http://tradingeducationprogram.org/2009/05/06/eurusd-83-pips-profit/

I had also mentioned that EURJPY shows repeated pattern. And that is a pattern to short EURJPY. I had shorted EURJPY at 131.95 and closed my position at 130.46 for 149 pips profit.
See: http://tradingeducationprogram.org/2009/05/06/eurjpy-149-pips-profit/

Chris, George Soros said his success rate is only 50%, this makes him one of the best (if not the best) hedge fund manager in the world. He is still very profitable because he cut loss on losing trades and let his profit run on the winning trades.

hi there,

it had been a busy busy year of late, so many things to buy and sell.
let me try to clear some confusion in your mind.

contrarian or trend following, to put stop loss or not to put stop loss, to cut loss or to average losses, to be bold or fear, to be greedy or consurvative, confident or timid.

which is correct? the answer is all of the above.
yes, you have to be confident n fearful, bold but timid……

if u are fearful every time the market clash, learn to be bold, if u are happy like everyone else when market top, learn to be fearful. lack of anyone of above will not make you a winning trader.

stop searching for the right sword to use, any sword will do the job of chopping.

its all from within.

best wish.
