L’idée centrale de cette stratégie est d’ajuster dynamiquement la taille de la position en fonction de l’évolution de la courbe des capitaux, d’augmenter la position en cas de profit et de réduire la position en cas de perte, afin de contrôler le risque global. La stratégie combine à la fois l’indicateur de dynamique Chande, l’indicateur SuperTrend et l’indicateur de dynamique pour identifier les signaux de négociation.
La stratégie utilise deux méthodes pour déterminer si la courbe des capitaux est en baisse: 1) calculer les moyennes mobiles simples rapides et lentes de la courbe des capitaux, jugées baisses si la SMA rapide est inférieure à la SMA lente; 2) calculer la courbe des capitaux avec la moyenne mobile simple de sa propre période plus longue, jugée baissée si la courbe des capitaux est inférieure à cette moyenne mobile.
Lorsque la courbe des capitaux est jugée à la baisse, la position est réduite ou augmentée en fonction de la configuration. Par exemple, si une réduction de 50% est définie, la position de 10% est réduite à 5%. La stratégie permet d’augmenter la taille de la position en cas de profit et de réduire la taille de la position en cas de perte pour contrôler le risque global.
Cette stratégie est clairement conçue, utilise la courbe des capitaux pour ajuster les positions dynamiquement, permet de contrôler efficacement les risques et mérite d’être testée et optimisée. La stratégie de paramétrage et de stop-loss doit également être bien pensée pour éviter les risques liés aux opérations radicales.

//EXPLANATION
//"Trading the equity curve" as a risk management method is the
//process of acting on trade signals depending on whether a system’s performance
//is indicating the strategy is in a profitable or losing phase.
//The point of managing equity curve is to minimize risk in trading when the equity curve is in a downtrend.
//This strategy has two modes to determine the equity curve downtrend:
//By creating two simple moving averages of a portfolio's equity curve - a short-term
//and a longer-term one - and acting on their crossings. If the fast SMA is below
//the slow SMA, equity downtrend is detected (smafastequity < smaslowequity).
//The second method is by using the crossings of equity itself with the longer-period SMA (equity < smasloweequity).
//When "Reduce size by %" is active, the position size will be reduced by a specified percentage
//if the equity is "under water" according to a selected rule. If you're a risk seeker, select "Increase size by %"
//- for some robust systems, it could help overcome their small drawdowns quicker.
