RSI Sobrecomprado/Sobrevendido (RSI Overbought/Oversold)

Este sistema opera reversões usando o Índice de Força Relativa (RSI). Quando o RSI cai abaixo do nível de sobrevendido, compra após fechar quaisquer posições vendidas. Quando o RSI sobe acima do nível de sobrecomprado, vende após fechar as posições compradas.

Os testes indicam um retorno anual médio de aproximadamente 61%. Funciona melhor no mercado de criptomoedas.

As posições são fechadas quando o RSI retorna a uma zona neutra ou o stop-loss é atingido.
