Este indicador é o Mobo Bands (Momentum Breakout Bands). Estas bandas são bandas de bollinger que têm um desvio padrão ajustado. Há sinais de compra quando tem breakouts de momento acima das bandas para movimentos para cima e sinais de venda quando tem breakouts de momento abaixo das bandas para movimentos para baixo. As bandas simplesmente sugerem que todos os mercados têm períodos dos quais todos sabemos que são verdadeiros. Enquanto o preço está dentro das bandas, diz-se que não tem tendência. Uma vez que as breakouts acontecem, você pode fazer negócios na direção do breakout.
