Time series objects

This chapter deals with more in-depth properties of time series objects. Knowledge of these special features is not necessary for the first steps with MM-Talk.

Time series objects represent value trends over time (e.g. indicator lines, price trends). Each piece of price information is assigned time information. You can therefore not only query entire time series, but also individual data at a specific point in time. The trading conditions of trading systems are also defined by time series.

It is characteristic of time series objects that they generally represent not just one value progression, but several. In practice, this is particularly relevant in the following cases:

• Price time series not only depict the price development of a security, but are also the central interface for all price data available for a security. They can provide all available price data for a security, depending on which price time series is requested with the function used.
  An indicator can obtain the high, low and close prices as well as the turnover of a security from a single price time series object. In this way, charts based on several price movements (e.g. candlestick charts) are supplied with all the necessary data by a single time series object.

• Multiline time series are formed (in formulaic terms) by combining several time series. They can be used to display several related time series in the chart at the same time, e.g. the MACD indicator, which is made up of the actual indicator trend and the trigger line, which is calculated from the trend. The same applies to the DMI, the Bollinger Bands, etc.
  For more information, see Application examples for time series.
  For each security, there is only one price time series object for which one of the curves, e.g. the close curve, is defined as the default. This standard history is always delivered if no other history is explicitly requested. In principle, however, any price time series object can provide all available price data.

Not all theoretically conceivable curves are available for every time series object. For example, a fund only has a redemption and issue price, but not a low or open price (in Infront Portfolio Manager, the redemption price is saved as a spot price, the issue price as a high).
