概要

この戦略は,主に,短期的に株が過剰に売れたときに反トレンドの機会を見つけるために移動平均の原則を利用する. 急速な移動平均がスロームービング平均を下回ると,株が下落傾向にあることを示します. 価格が一定の幅で急速な移動平均を突破すると,ダウンサイドは制限され,ブランスは起こりえます. この戦略は,価格が急速な移動平均を上回るときにロングでそのような過剰販売のブランスを捕捉することを目指します.

戦略の論理

  1. 8EMAのような高速移動平均と 20SMAのような遅い移動平均を設定します

  2. SMAが EMA の上にある場合,上昇傾向を示します. SMAが EMA の下にある場合,下落傾向を示します.

  3. 価格がEMAを一定幅 (例えば2-10%) に突破すると,株は過剰に売られ,反発する可能性が高くなります.

  4. 価格が EMA を越えて戻ると 買い信号が発信されます

  5. ストップ・ロスを EMA 近くに設定し,中間 SMA (例えば 50SMA) 近くで利益を得るか,または利益を得られる割合を使用します.

  6. 価格がEMAを下回る時 清算する

利点

  • 移動平均の信頼性の高い原理を使用します

  • 急速なEMAと過剰売り上げの利回りにより バウンスの確率は向上します

  • ストップ・ロスを調整できるし 利益を控えるリスク

  • 柔軟なポジションサイズが 異なるリスク・アパセットに合致します

リスク

  • 失敗したブランスは 過剰に売れた利益率にもかかわらず 起こり得ます

  • 移動平均値は遅延があり,ローカルブーンスを見逃す可能性があります.

  • ストップ・ロスはEMAの近くで 易易易にストップできます

  • 手動で調整し 結果に大きく影響します

  • 結果は採集と相関しています

増進 の 機会

  • 逆トレンド取引を避けるためにトレンドフィルターを追加します.

  • 確率を増やすために音量フィルターを追加します.

  • 静的ではなく動的ストップ損失を考慮してください.

  • 依存を減らすための最適なパラメータを研究します

  • より良い選択のために 採集を組み込む

結論

この戦略は明確な論理を持ち,典型的な移動平均逆転システムとして理解しやすい.利点は安定性とリスク制御であり,初心者にとって適している.しかし,逆転点を誤って判断するリスクも伴っている.追加のフィルター,ダイナミックストップ,パラメータ最適化などによる改善により強度が向上する.全体的には,学ぶ価値のある健全な短期平均逆転フレームワークを示している.

//*********************Notes for continued work***************

//************************************************************

//I. Intro
//This strategy is designed to allow you to catch the bounce or "SNAP Back" of a equity that has been in a downward trend.
//Once the moving averages are in the order of 200SMA > 50 SMA > 34EMA > 20SMA > 8EMA, the strategy is setup.
//Next you wait for a trigger of the closing price crossing over the 8EMA, while there is a desired gap size between the 8EMA and the 20SMA (2-10% of stock value preferred).
//Exit position based on target profit reached (conservative sell half at 34EMA and engage a trailing stop loss for remainder or set static limit) or price crosses 8EMA or stop loss%
//*)This code also allows you to determine your desired backtesting date compliments of alanaster
//This code is the product of many hours of hard work on the part of the greater tradingview community.  The credit goes to everyone in the community who has put code out there for the greater good.
//The idea for the coding came from video I watched on YouTube presented by TradeStation called Snap Back - thank you guys for the inspiration.


//UPDATE: I have coded the other side of the strategy to allow you to take advantage of the same set-up in an uptrend for Short plays.  You can turn the up or downsides on, off, or both.

//Happy Hunting!
