Strategi ini berdagang berdasarkan Indeks Pergerakan Arah Dimodifikasi (DMI). DMI dimodifikasi membandingkan perbezaan antara penunjuk arah positif (+DI) dan penunjuk arah negatif (-DI) untuk menilai arah trend.
Logik perdagangan adalah:
Mengira +DI dan -DI dalam tempoh
Peta nilai +DI dan -DI kepada julat dari 100 hingga -100
Merangka perbezaan antara +DI dan -DI sebagai garis DMI yang diubah suai
Pergi panjang apabila DMI yang diubahsuai melintasi di atas 0
Pergi pendek apabila DMI yang diubahsuai melintasi di bawah 0
Pilihan pelinciran garis DMI untuk menapis isyarat palsu
Strategi ini secara langsung membandingkan kekuatan relatif +DI dan -DI untuk menentukan trend, mengatasi batasan penunjuk tunggal.
DMI yang diubah suai secara intuitif mencerminkan perbandingan +DI/-DI
Lemeskan penapis DMI palsu
Jelas titik isyarat panjang/pendek
DMI sendiri mempunyai lag, mungkin terlepas masa
Tempoh parameter memerlukan pengoptimuman
Rendah kepada whipsaws di pasaran bergolak
Strategi ini menilai perubahan arah trend melalui DMI yang diubah suai, menyediakan pandangan alternatif untuk perdagangan trend.

// 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 ==
