C'est juste une simulation approximative, pour que tout le monde ait une idée précise de la quantité de marges perdues.
Regardez d'abord le rapport original:https://www.fmz.com/digest-topic/5584et le rapport amélioré:https://www.fmz.com/digest-topic/5588
La stratégie a été partagée publiquement depuis 4 jours maintenant. La première étape s'est très bien déroulée, avec des rendements élevés et peu de rétracements, de sorte que de nombreux utilisateurs utilisent un effet de levier très élevé pour parier un rendement de 10% par jour. Cependant, comme indiqué dans le rapport initial, il n'y a pas de stratégie parfaite. Vendre court sur la tendance à la hausse et acheter long sur la tendance à la baisse utilisent les caractéristiques des altcoins pour augmenter et chuter ensemble. Si une monnaie s'éloigne d'une tendance unique, elle accumulera de nombreuses positions de détention. Bien qu'une moyenne mobile ait été utilisée pour suivre le prix initial, les risques existent toujours. Ce rapport quantifie principalement les risques spécifiques et pourquoi le paramètre recommandé trade_value représente 3% des fonds totaux.
Afin de mettre en évidence le code, nous mettons dans avancé de cette partie, tout le monde devrait essayer d'abord exécuter le code suivant (à partir de la partie des bibliothèques d'importation).
Pour simuler, nous supposons qu'il y a 20 monnaies, mais il suffit d'ajouter BTC et ETH, et d'utiliser BTC pour représenter 19 monnaies à prix constants.
Tout d'abord, simuler la situation où le prix d'une seule monnaie continue d'augmenter. Stop_loss indique que le stop loss dévie. Ici, il ne s'agit que d'une simulation. La situation réelle aura un retracement intermittent, ce ne sera pas aussi mauvais que la simulation.
Supposons qu'il n'y ait pas de retracement vers cette devise, lorsque l'écart de stop loss est de 0,41, ETH a augmenté de 44% à ce moment-là, et les résultats ont finalement été perdus 7 fois de la valeur de négociation, c'est-à-dire trade_value * 7. Si trade_value est réglé à 3% du total des fonds, alors la perte = total des fonds * 0,03 * 7. Le retracement maximal est d'environ 0,03 * 7 = 21%.
Vous pouvez estimer votre propre tolérance au risque sur la base des résultats ci-dessous.

En simulant la situation de baisse continue, la baisse est accompagnée d'une diminution de la valeur du contrat, de sorte que le risque est plus élevé que la hausse, et à mesure que le prix baisse, le taux d'augmentation des pertes s'accélère. Lorsque la valeur de l'écart de stop loss est de -0,31, le prix de la devise chute de 33% à ce moment-là, et une perte de 6,5 transactions. Si le montant du commerce trade_value est fixé à 3% des fonds totaux, le retracement maximum est d'environ 0,03 * 6,5 = 19,5%.
