Strategi ini disebut
Pola pembalikan 123 mengacu pada harga yang bergeser secara signifikan selama tiga hari berturut-turut dengan hari ketiga ditutup ke arah yang berlawanan dari dua hari sebelumnya.
Indikator transformasi Fisher menormalkan harga menjadi kurva seperti Gaussian, dan titik balik swing ekstremnya dapat secara efektif mengidentifikasi pembalikan harga.
Logika perdagangan adalah:
Pola pembalikan 123 menunjukkan sinyal beli atau jual.
Kurva transformasi Fisher menunjukkan sinyal beli atau jual.
Ketika keduanya memberikan sinyal bersamaan, perdagangan beli atau jual yang sesuai diambil.
Ketika keduanya memberikan sinyal yang berlawanan, posisi tetap flat.
Keuntungan dari strategi ini adalah kombinasi indikator dapat meningkatkan keakuratan penilaian waktu pembalikan.
Kesimpulannya, integrasi indikator membentuk perspektif analisis yang lebih komprehensif.

// This is combo strategies for get a cumulative signal.
//
// First strategy
// This System was created from the Book "How I Tripled My Money In The
// Futures Market" by Ulf Jensen, Page 183. This is reverse type of strategies.
// The strategy buys at market, if close price is higher than the previous close
// during 2 days and the meaning of 9-days Stochastic Slow Oscillator is lower than 50.
// The strategy sells at market, if close price is lower than the previous close price
// during 2 days and the meaning of 9-days Stochastic Fast Oscillator is higher than 50.
//
// Second strategy
// Market prices do not have a Gaussian probability density function
// as many traders think. Their probability curve is not bell-shaped.
// But trader can create a nearly Gaussian PDF for prices by normalizing
// them or creating a normalized indicator such as the relative strength
// index and applying the Fisher transform. Such a transformed output
// creates the peak swings as relatively rare events.
// Fisher transform formula is: y = 0.5 * ln ((1+x)/(1-x))
// The sharp turning points of these peak swings clearly and unambiguously
// identify price reversals in a timely manner.
//
// WARNING:
// - For purpose educate only
// - This script to change bars colors.
