Então, gostei da EA feita e divulgada como apresentação de redes neurais (https://www.mql5.com/pt/articles/497), queria testar mas é inviavel ver o resultado sem um stop loss, take profit, trailing ou hora para parar. Sei que não é para se usar como uma EA mas por incrivel que pareça ela deu mais certo que 98% das EA's que tentei escrever... Peço ajuda, e muito obrigado (codigo abaixo)

Atualmente, todo negociador já deve ter ouvido falar sobre redes neurais e sabe como é interessante utilizá-las. A maioria acredita que as pessoas que sabem lidar com redes neurais são algum tipo de super-humano. Neste artigo, tentaremos explicar a arquitetura da rede neural, descrever as suas aplicações e apresentar exemplos de uso prático. O...
