This strategy trades based on the Modified Directional Movement Index (DMI). The modified DMI compares the difference between positive directional indicator (+DI) and negative directional indicator (-DI) to judge trend direction.
The trading logic is:
Calculate +DI and -DI over a period
Map +DI and -DI values to a range from 100 to -100
Plot the difference between +DI and -DI as the modified DMI line
Go long when modified DMI crosses above 0
Go short when modified DMI crosses below 0
Optional smoothing of DMI line to filter false signals
The strategy directly compares the relative strength of +DI and -DI to determine trend, overcoming limitations of single indicators.
Modified DMI intuitively reflects +DI/-DI comparison
Smoothing DMI filters fakeouts
Clear long/short signal points
DMI itself has lag, may miss timing
Parameter period requires optimization
Prone to whipsaws in choppy markets
This strategy judges trend direction change through the modified DMI, providing an alternative view to trend trading. But DMI’s lagging nature needs caution, and can be combined with other confirming indicators.

// 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
