In this presentation, we will look at how we actually enter a trade, once we have a set up. Is this a clean simple process, like “enter at open on Monday morning” or some other way? For some, it can be a tricky piece of psychology actually taking the plunge. Do you have last minute ideas that veto the trade? During the presentation we want to hear from members on what methods they use. Please have your stories ready and contribute to the discussion.

Inside Indicators: Trailing Stops

Source: P2013 SYD Available to: Members

Indicators are used throughout technical trading as components of trading systems. Selected indicators will be dismantled, serviced, adjusted and rebuilt in this series of talks. This month we look at trailing stops. These can form our entry and exit signals within a system. They are an integral part of risk management. You can defensively hold your shoulder against the lowest low stop, rocket up with a parabolic stop, dangle from a chandelier stop, or tease with a volatility target. Whichever you chose, it can be an interesting ride. (Note: No video taken at presentation.)

Inside Indicators: ADX

Posted: 1 April, 2013 Subjects: Indicators

Indicators are used throughout technical trading as components of trading systems. Selected indicators will be dismantled, serviced, adjusted and rebuilt in this series of talks. The ADX ( Average Directional Movement Index ) is an index used to measure the strength of a trend. Developed by Welles Wilder back in 1978 before PCs, it can be used to compare trends in different charts, or to help assess the state of a trend in a particular chart. (Note: No video taken at presentation.)

Indicators are used throughout technical trading as components of trading systems. Selected indicators will be dismantled, serviced, adjusted and rebuilt in this series of talks. Yes O,H,L,C is an indicator! It summarizes a vast amount of data as a means to extract some sort of readable information out of the market noise.

Inside Indicators: Moving Averages

Indicators are used throughout technical trading as components of trading systems. Selected indicators will be dismantled, serviced, adjusted and rebuilt in this series of talks. This month we look at moving averages. This is one of the most useful indicators in technical analysis. How do they work? We will try to answer the age old question; What is the difference between cross-moving averages and happy-moving averages.

Inside Indicators: Stochastic

Posted: 1 September, 2012 Subjects: Indicators
Source: P2012 Available to: Members

This month we look at The Stochastic Oscillator.  A stochastic process is one which combines predictable actions and a random element.  That sounds just like trading!  We will also look at the “Premier” stochastic ( The oscillators  Hot Rod cousin ) which is thought to have mag wheels and chrome rocker covers.

Inside Indicators: MACD

Posted: 1 August, 2012 Subjects: Indicators
Source: P2012 Available to: Members

This month we look at MACD;  Moving Average Convergence / Divergence. 

This indicator is based on the difference between two moving averages.  From this simple innocent data stream, many stories are squeezed, teased,  cajoled and coerced.  Come into the torture chamber and we will make it talk.

Inside Indicators: RSI

Posted: 1 July, 2012 Subjects: Indicators
Source: P2012 Available to: Members

This month we look at Relative Strength Index.  It is a way of measuring overbought or oversold;  How strong is the price spike up or down.  It compares the decisiveness of a move with its inbuilt hesitation.  It is the core of some mean reversion systems which give a very good hit rate; trading off the back of price spikes. 

Inside Indicators: ATR

Posted: 1 June, 2012 Subjects: Indicators
Source: P2012 Available to: Members

This month Average True Range is examined.  ATR is a measure of market noise which is used throughout many trading systems.  We will look at the nature of the noise and whether ATR does the job of measuring this noise.  We will look at composite indicators where ATR is used as a universal unit of measurement, allowing comparisons between charts of shares, futures and forex.

Random or What

Peter would like the word “twaddle” to be brought back into popular usage.  We have been genetically selected to be biased towards giving meaning to false information,  ( Accepting twaddle ). This can be very useful for survival and reproduction, but this can badly effect our trading.               

As a way of understanding the problem of giving false meaning, synthetic charts have been created.   These charts show many interesting familiar patterns,  patterns created by chance events without any real meaning.  

Why are we so vulnerable to these errors, and how can we tread the path between being too gullible and being too sceptical.
