Directional Movement Index

DMI(close; high; low; period)
The first three arguments are arrays:
- 'close' contains the closing prices
- 'high' contains the high prices and
- 'low' - the low prices.

The 'period' argument defines the period for the function - it must be a constant greater or equal to 1.
The result is an array. The first 'period' elements are marked as invalid.

The Directional Movement Index is developed by J. Welles Wilder. The DMI helps identify whether there is a definable trend in a market, and in which direction that trend is moving. The ADX function, which is a part of the Directional Movement System, is based on the DMI. The formula of the DMI is:

where (+DI) is the current value of the Positive Directional Index and (-DI) is the current value of the Negative Directional Index. For internal calculations the DMI function uses the modified moving average.
