Technical Analysis Functions

Dagobert provides all common functions for technical analysis, such as moving averages, oscillators, candlestick pattern detectors, strength indices, and Hilbert transformations. The zero crossing or reaching of a certain limit of a technical analysis function is often used as an indicator for trade signals.

Parameters:

offset	The bar number for which the value is calculated, relative to the current bar; can be omitted for using the current bar.
fastPeriod	The number of bars for the first period, if any; normally 12, minimum 2.
slowPeriod	The number of bars for the second period, if any; normally 26, minimum 3.
signalPeriod	The number of bars for the third period, if any; normally 9, minimum 2.

Range:

+/-Price variation, dependent on the asset

Usage:

macd(12,26,9) calculates the standard MACD for the current bar; macd(3,12,26,9) calculates the standard MACD for 3 bars ago.

Remarks:

The MACD is taken from the closing price. It is cumulative, i.e. its value depends on the values of all bars before (see aut.nUnstablePeriod).
At the initial run of the strategy, aut.nHistory is automatically adjusted to the sum of the fastPeriod and slowPeriod.
When the function is used in the strategy, the MACD is also automatically plotted in the output chart.

Example:

// when the MACD Histogram goes above zero, buy long 
if (crossOver(macdHist(12,26,9),constant(0)))
  buyLong(0);
// sell when it goes below zero
if (crossUnder(macdHist(12,26,9),constant(0)))
  sellLong(0);
