- Technical analysis software
Technical analysis software automates the charting, analysis and reporting functions that support technical analysts in their review and prediction of
financial market s (eg. thestock market ).Description of Technical Analysis Software Features
The following are descriptions of the most common features of technical analysis applications. Some software may focus on only one aspect (say back testing) and the combination of more than one software package is often required to build a fully automated trading system.
Charting
A graphical interface that presents price, volume and technical analysis indicators through a variety of visual interfaces such as line, bar, candlestick and Open-high-low-close (OHLC) charts. The chart data is presented as a time series and users typically have the ability to view historical data with varying interval (sampling) periods. Interval periods range from seconds through to months; short term traders tend to use frequent interval periods, such as 1 minute i.e. the price data is updated every 1 minute, whereas longer term traders tend to use daily, weekly or monthly interval periods when trying to identify price and technical analysis trends. Some charting packages enable users to draw support and resistance trend line or for example fibonacci retracements to help establish trending patterns.
Back testing
Enables traders to test technical analysis investment timing strategies against historical price movement for one or more specific securities. Strategies are compared to each other using diverse performance measurements such as maximum drawdown, annual profit and
Sharpe ratio . The objective is to try and develop a trading strategy based on technical analysis indicator criteria, which will generate a positive return.Optimisation
A process of testing technical analysis indicator parameters, with the view to developing an investment strategy that generates the maximum return based on historical price movement. The optimisation process is achieved through the fine-tuning of the associated technical analysis charting parameters. Typically technical analysis indicators have a range of parameters that can be adjusted, such as the interval period and the technical analysis indicator variables. For example the Stochastic indicator has four parameters that effect its results: %k, %d, slowing period, interval period. Optimisation must be performed carefully to avoid
curve fitting . Back testing of an over-optimised system will perform admirably with past data because it becomes a good approximation function that fits the past data, however it is not uncommon to see a lesser performance when evaluated in real-time. One way to diminish over-optimisation is by carrying out optimisation on historical data and then performing future testing (sometimes referred to as 'out of sample') before making a final evaluation of a trading strategy.canner
Scanners enable users to 'scan' the market, be it stocks, options, currencies etc, to identify investment opportunities that meet a user's specific investment criteria. Using a technical analysis scanner, a user could, for example, scan the market to identify oversold stocks that have stochastic and RSI value of less than 20% and 30 respectively.
Alerts
Alert software is used to monitor specific equities, such as stocks, options, currencies, warrants, etc, and provide a notification of when specific price, volume and technical analysis investment conditions are met. As an example, a person who uses technical analysis might want to be notified when the RSI indicator rises above 70, followed by the price falling below its 20 day moving average; using alerting software the user will be able to create an alert, which will provide a notification of when the technical analysis investment conditions are met. When alert conditions are met, a notification is typically communicated via an on screen pop up or sent as an email, instant message or text alert (to a mobile phone).
Custom Indicators
Most technical analysis software includes a library of de-facto standard indicators (e.g.
moving average s,MACD ....). Some software will also provide a mean to customize, combine or create new indicators. This is typically achieved with a proprietaryscripting orgraphical language .Data Feed
Technical analysis software is typically used with End Of Day (EOD), delayed or real time data feeds. EOD data feeds provide the end of day closing price for the given equity and is typically updated once a day at market close. Delayed data is typically delayed 15 to 30 minutes depending on the exchange and is the most commonly used data feed typeFact|date=December 2007. Real time data feeds provide tick by tick 'real time' data. Real time data is licensed on a per-exchange basis whereas delayed data is typically purchased on a regional basis, such as US markets, rather than an exchange basisFact|date=December 2007.
Broker Interface
Some technical analysis software can be integrated with brokerage platforms to enable traders to place trades via a user interface that they are familiar with. Typically these software providers try to differentiate themselves from the brokerage software through enhanced features such as automated trading.
Technical Analysis Software Platform Support
Technical Analysis Software is available in the form of commercial or
Open Source software. Such software may be available on a computer, or on a mobile phone or PDA.Mobile phone andpersonal digital assistant (PDA) devices allow a user to access online technical analysis packages when away from their computer. However, packages that require the use ofJava applet s may not work on older model mobile phones or PDAs. Online technical analysis software packages provide access from any Internet-connected computer (including a suitably equipped mobile or PDA), but may require the user to store their information with the provider. Installed, downloaded software will only be available on the computers that the user has downloaded and installed it on.Feature comparison of Technical Analysis Software
