Os mercados frequentemente respeitam as linhas de tendência traçadas através de máximas ou mínimas anteriores de swing. Esta estratégia ajusta automaticamente linhas de regressão à ação de preço recente e procura velas que ricocheteiem nessas linhas na direção da tendência dominante.
Os testes indicam um retorno anual médio de aproximadamente 124%. Funciona melhor no mercado de câmbio.
Velas recentes são armazenadas para calcular linhas de suporte e resistência inclinadas para cima ou para baixo. Quando o preço se aproxima de uma linha de tendência e uma vela confirma o rebote enquanto permanece no lado correto de uma média móvel, o sistema abre uma operação. O stop é definido usando um percentual do preço e a saída ocorre no cruzamento da média móvel.
Ao operar apenas na direção predominante e aguardar uma reação clara no suporte ou resistência, o método tenta capturar movimentos de continuação sem perseguir rompimentos.
Detalhes
Critérios de entrada: O preço toca a linha de tendência calculada e a vela fecha na direção da tendência acima/abaixo da MA.
Comprado/Vendido: Ambos.
Critérios de saída: Preço cruzando a média móvel ou stop-loss.
Stops: Sim, baseados em percentual.
Valores padrão:
TrendlinePeriod = 20
MAPeriod = 20
BounceThresholdPercent = 0.5
CandleType = 5 minute
StopLossPercent = 2
