Strategi ini dinamakan
Corak pembalikan 123 merujuk kepada harga yang berlainan dengan ketara selama tiga hari berturut-turut dengan hari ketiga ditutup ke arah yang bertentangan dengan dua hari sebelumnya.
Penunjuk transformasi Fisher menormalkan harga ke dalam lengkung seperti Gaussian, dan titik giliran swing yang melampau dapat mengenal pasti pembalikan harga dengan berkesan.
Logik perdagangan adalah:
Corak pembalikan 123 menunjukkan isyarat beli atau jual.
Kurva transformasi Fisher menunjukkan isyarat beli atau jual.
Apabila kedua-dua memberi isyarat serentak, perdagangan beli atau jual yang sepadan diambil.
Apabila kedua-dua memberi isyarat yang bertentangan, kedudukan disimpan tetap.
Kelebihan strategi ini adalah gabungan penunjuk boleh meningkatkan ketepatan penghakiman masa pembalikan.
Kesimpulannya, integrasi penunjuk 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.
