この戦略は,価格の標準差を計算して,価格が異常な大幅な変動があるかどうかを判断する.価格が異常な大幅な変動があるときは,価格の逆転の機会として判断して,逆操作を行う.
この戦略は主に2つの指標を用いています.
wvf = ((highest(close, pd)-low)/(highest(close, pd)))*100
sDev = mult * stdev(wvf, bbl)
midLine = sma(wvf, bbl)
lowerBand = midLine - sDev
upperBand = midLine + sDev
その中で,wvfは価格変動率であり,sDevは標準差であり,midLineは平均線であり,lowerBandとupperBandはそれぞれ下限線と上限線である.価格が上限線を超えると,異常な変動が発生していると考えられる.
fastup = rma(max(change(close), 0), 7)
fastdown = rma(-min(change(close), 0), 7)
fastrsi = fastdown == 0 ? 100 : fastup == 0 ? 0 : 100 - (100 / (1 + fastup / fastdown))
RSIが特定の値を下回ると,価格が超売り状態にあることを示し,反発が起こり得る. RSIが特定の値を超えると,価格が超買い状態にあることを示し,反発が起こりうる.
この戦略の出入りの論理は以下の通りです.
多ポジションの入場:価格が上限線を超えたり,変動率が値を超えたり,RSIが特定の値を下回ったときに多めに入場する.
空置入場:価格が上限線を超えたり,波動率が値を超えたり,RSIが特定の値を超えたときに空置する.
退出条件:開設方向とK線実体方向の反対で平仓する.
この戦略は,価格の変動率の標準差を計算して,価格が異常波動しているかどうかを判断し,逆転の機会を捉える.入場タイミングの選択では,RSI指標と組み合わせて価格の超買い超売り状態を判断し,精度を高めます.ストップの方法では,単純な実体方向のストップを適用します.全体的に,この戦略は,統計データを用いて異常波動を判断し,効果は良好ですが,パラメータをさらに最適化し,安定性を向上させる必要があります.
