Diese Strategie handelt auf der Grundlage des Modified Directional Movement Index (DMI). Der modifizierte DMI vergleicht die Differenz zwischen dem positiven Richtungsindikator (+DI) und dem negativen Richtungsindikator (-DI), um die Trendrichtung zu beurteilen.
Die Handelslogik lautet:
Berechnung von +DI und -DI über einen Zeitraum
Karte der Werte +DI und -DI auf einen Bereich von 100 bis -100
Zeichnen Sie die Differenz zwischen +DI und -DI als modifizierte DMI-Linie
Verlängern, wenn der modifizierte DMI über 0 liegt
Kurzschluss, wenn der modifizierte DMI unter 0 fällt
Optionale Glättung der DMI-Leitung zur Filterung falscher Signale
Die Strategie vergleicht die relative Stärke von +DI und -DI unmittelbar, um den Trend zu bestimmen, und überwindet die Einschränkungen einzelner Indikatoren.
Das modifizierte DMI spiegelt den +DI/-DI-Vergleich intuitiv wider
Glättung von DMI-Filtern für Fakeouts
Lange/kurze Signalepunkte klarstellen
DMI selbst hat Verzögerung, kann das Timing verpassen
Parameterperiode erfordert Optimierung
Anfällig für Schlagsägen auf unruhigen Märkten
Diese Strategie beurteilt den Trendwinkelwechsel anhand des modifizierten DMI und bietet eine alternative Sicht auf den Trendhandel.

// As promised a strategy of my DMI Modified indicator! (See link below for indicator).
// === How does it work? ===
// Instead of plotting the positive direction of +DI and negative direction for -DI, we subtract the +DI with the -DI on scales of 100 to -100.
// The result is plotted with a oscillator to identify the current trend.
// DMI Modified supports multiple moving averages (default is EMA with length of 9). You can disable moving averages smoothing in settings.
//== About the Strategy ==
// Buys when the line crosses over the Zero line.
// Sells when the line crosses under the Zero line.
// The DMI modified strategy is pretty much clean, without any filtering besides the DMI Modified and a moving average to smooth it.
// Works best to catch a trend and more suitable for 1 hour and above time frame. Stay tuned for updates.
// == Oscillator Colors ==
// GREEN : Strong Up Trend as DMI Modified is above zero line and DMI modified is ascending.
// LIGHT GREEN: Still up trend but weakening as DMI modified is above zero but descending.
// RED: Strong Downtrend as DMI Modified is below zero line and DMI modified is descending.
// LIGHT RED: Still down trending but weakening as DMI modified is below zero but ascending.
// == Notes ==
// Short is enabled by default.
// Can also be used to find divergences.
// Bar coloring is disabled by default
// == Links ==
