Cette stratégie est appelée
Le modèle de renversement de 123 fait référence à des prix qui varient considérablement sur trois jours consécutifs, le troisième jour se clôturant dans la direction opposée aux deux jours précédents.
L'indicateur de transformation de Fisher normalise les prix dans une courbe de type gaussienne, et ses points de basculement extrêmes peuvent identifier efficacement les renversements de prix.
La logique de négociation est la suivante:
Le schéma de renversement 123 montre des signaux d'achat ou de vente.
La courbe de transformation de Fisher montre des signaux d'achat ou de vente.
Lorsque les deux donnent des signaux concurrents, les transactions d'achat ou de vente correspondantes sont effectuées.
Lorsque les deux donnent des signaux opposés, les positions sont maintenues stables.
L'avantage de cette stratégie est que la combinaison d'indicateurs peut améliorer la précision de jugement du timing de l'inversion.
En conclusion, l'intégration des indicateurs constitue une perspective analytique plus complète.

// 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.
