この戦略は,方向トレンド指数 (DTI) を利用して価格トレンドの方向を判断し,トレンドを追跡する取引システムである.DTIは,一定の周期内の最高価格と最低価格の変化方向を比較してトレンドを判断し,上下値の設定で取引信号を生成する.DTIが軌道に乗るときは多し,下下軌道に乗るときは空にする.
ある周期内の最高価格変化と最低価格変化を計算し,価格変化値を得る.価格変化値に複数の指数移動平均を施し,DTI曲線を得る.DTIの上下値を設定し,指標上の値を突破すると多信号,下値を突破すると空信号を生じ,次の信号が現れるまで保持する.
計算周期を適当に短縮し,値パラメータを調整し,または他の指標と組み合わせてトレンドの逆転を判断する.
DTI戦略は,明確な指標信号によってトレンドの方向を判断し,長期にわたって安定した利益を達成することができます.パラメータ最適化などのさらなる改善により,優れたトレンド追跡戦略になることができます.

// This technique was described by William Blau in his book "Momentum,
// Direction and Divergence" (1995). His book focuses on three key aspects
// of trading: momentum, direction and divergence. Blau, who was an electrical
// engineer before becoming a trader, thoroughly examines the relationship between
// price and momentum in step-by-step examples. From this grounding, he then looks
// at the deficiencies in other oscillators and introduces some innovative techniques,
// including a fresh twist on Stochastics. On directional issues, he analyzes the
// intricacies of ADX and offers a unique approach to help define trending and
// non-trending periods.
// Directional Trend Index is an indicator similar to DM+ developed by Welles Wilder.
// The DM+ (a part of Directional Movement System which includes both DM+ and
// DM- indicators) indicator helps determine if a security is "trending." William
// Blau added to it a zeroline, relative to which the indicator is deemed positive or
// negative. A stable uptrend is a period when the DTI value is positive and rising, a
// downtrend when it is negative and falling.
//
// You can change long to short in the Input Settings
// Please, use it only for learning or paper trading. Do not for real trading.
