Devido a razões de liquidez, quando há uma grande quantidade de esmagamento e puxa no mercado, inevitavelmente haverá grandes flutuações de preços, e uma diferença de preço instantânea será formada entre as bolsas, e a estratégia é capturar esses momentos em que os negócios rápidos são executados para completar o processo de comprar baixo e vender alto. Alguns clientes me perguntaram por que eu tenho que obter tantas trocas. Isso é inevitável. O que ganhamos é a diferença de preço instantânea entre as trocas. Quanto mais trocas, mais oportunidades para a diferença de preço formada após o crossover.
