Strategi ini mengesan peluang pembalikan harga dengan mengira penyimpangan standard turun naik harga. Apabila terdapat turun naik harga yang luar biasa besar, ia dianggap sebagai peluang untuk pembalikan harga, dan kedudukan perdagangan terbalik diambil.
Strategi ini menggunakan dua penunjuk utama:
wvf = ((highest(close, pd)-low)/(highest(close, pd)))*100
sDev = mult * stdev(wvf, bbl)
midLine = sma(wvf, bbl)
lowerBand = midLine - sDev
upperBand = midLine + sDev
Di mana wvf adalah turun naik harga, sDev adalah penyimpangan standard, midLine adalah garis purata, lowerBand dan upperBand adalah garis had bawah dan atas.
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))
Apabila RSI berada di bawah ambang, ia menunjukkan status oversold dan potensi bounce back. Apabila RSI melebihi ambang, ia menunjukkan status overbought dan potensi pullback.
Logik masuk dan keluar adalah:
Masuk panjang: Apabila harga melebihi had atas atau turun naik melebihi ambang, dan RSI di bawah nilai, pergi panjang.
Masuk pendek: Apabila harga melebihi had atas atau turun naik melebihi ambang, dan RSI melebihi nilai, pergi pendek.
Keluar: Apabila arah badan candlestick bertentangan dengan arah kedudukan, kedudukan dekat.
Strategi ini mengesan turun naik harga yang tidak normal melalui pengiraan penyimpangan standard turun naik harga, untuk menangkap peluang pembalikan. RSI digabungkan untuk menilai status overbought / oversold untuk meningkatkan ketepatan kemasukan. Stop loss arah lilin yang mudah digunakan. Secara keseluruhan, strategi ini berkesan dalam menggunakan data statistik untuk mengesan turun naik yang tidak normal, tetapi memerlukan pengoptimuman parameter lebih lanjut untuk meningkatkan kestabilan. Jika mekanisme stop loss dapat dioptimumkan dengan munasabah untuk mengurangkan kerugian, strategi akan berfungsi lebih baik lagi.
