Esta estratégia utiliza um método típico de rastreamento de tendências de duplo equilíbrio, em combinação com mecanismos de gestão de risco como stop loss, stop-loss e tracking stop loss, com o objetivo de capturar o lucro resultante de uma tendência.
Os riscos podem ser reduzidos através das seguintes medidas:
A estratégia pode ser melhorada em alguns aspectos:
Esta estratégia é, em geral, uma típica estratégia de seguimento de tendências de linha de equilíbrio de duas EMAs. Com os benefícios de capturar tendências, além de combinar meios de gestão de risco como parada, parada e rastreamento de perdas. Mas também há alguns problemas típicos, como alta sensibilidade à situação de ruído e vibração, que são facilmente encaixados.

// long ma

// === STRATEGY RELATED INPUTS ===

// === RISK MANAGEMENT VALUE PREP ===
// if an input is less than 1, assuming not wanted so we assign 'na' value to disable it.

// === SERIES SETUP ===
/// a couple of ma's..

// === PLOTTING ===

// is fast ma above slow ma?

// are we inverting our trade direction?

// === STRATEGY - LONG POSITION EXECUTION ===
