com identificadores CHART_PRICE_MIN e CHART_PRICE_MAX

Parece ser exatamente o que eu preciso. Muito obrigado!!!!

MakarFX:

retorna verdadeiro/falso , de que horas estamos falando?

A classe armazena o tempo do tick anterior e verdadeiro/falso não é devolvido pela classe, mas por uma função de membroda classe:

void OnTick()
{
    if (NB_M1.IsNewBar())  // (1) Если появился новый бар M1
        {....}
    ......
}

No código você afixou a barra apenas para o público!

Dado que a classe informa uma nova barra, o tempo é o iTime (tudo o que você precisa,0),

respectivamente da última vez que o iTime (tudo o que você precisa,1)

Z.U. Talvez você saiba como conseguir o tempo com frações de segundo...

MakarFX:

No código que você postou, o publc é apenas bool!

Considerando que a classe reporta uma nova barra, o tempo é o iTime (tudo o que você precisa,0),

respectivamente da última vez que o iTime (tudo o que você precisa,1)

Z.U. Talvez você saiba como obter o tempo em frações de segundo...

Meu erro, desculpe

Eu não preciso de frações de segundo. Preciso pegar o primeiro segundo de um novo bar

Tretyakov Rostyslav 2021.08.04 15:53 #15675

Mikhail Tkachev:

Errado um pouco, desculpe

Eu não preciso de frações de segundo. Preciso pegar o primeiro segundo de um novo bar

como este

datetime NB_M1;
int OnInit()
{
}

void OnTick()
{
   if (CIsNewBar(_Symbol,PERIOD_M1))  // (1) Если появился новый бар M1
        {NB_M1=TimeCurrent();}
    ......
}

e para salvar o valor anterior

datetime NB_01_M1, NB_02_M1;
int OnInit()
{
}

void OnTick()
{
   if (CIsNewBar(_Symbol,PERIOD_M1))  // (1) Если появился новый бар M1
        {NB_02_M1=NB_01_M1; NB_01_M1=TimeCurrent();}
    ......
}

Mikhail Tkachev 2021.08.04 15:57 #15676

então é assim

Obrigado, MakarFX, eu vou tentar)

законопослушный гражданин :

ok, obrigado, vou pensar sobre isso e executá-lo no testador.

por favor me diga mais sobre a função martin em seu código.

onde preciso substituir algo para que martin se espalhe para ordens lucrativas em vez de não lucrativas?

Onde devo substituir o quê, para que um martin seja aplicado a encomendas lucrativas em vez de perder as que se perdem?

AMarkov:
Isso parece ser o que você precisa. Muito obrigado!!!!

Esta não é a maneira de fazer isso! É assim que você obtém os preços mínimo e máximo do instrumento, não do oscilador. Um programador experiente tem vergonha de dar tais respostas a perguntas tão elementares...

Na verdade, você precisa obter os dados do oscilador usando o CopyBufer

    int s, len;
    double main[];
    double min, max;
    len = (int)ChartGetInteger(0, CHART_VISIBLE_BARS); // длина копируемых видимых значений
    s = (int)ChartGetInteger(0, CHART_FIRST_VISIBLE_BAR) - len + 1; // 1-й видимый бар минус длина -- начало копируемых баров
    if (CopyBuffer(handle, MAIN_LINE, s, len, main) != len)
      return;
    // handle - хэндэл осциллятора
    // MAIN_LINE - меняем на нужный индекс буфера осциллятора
    // получаем мин. и макс. значения
    min = main[ArrayMinimum(main, 0, WHOLE_ARRAY)];
    max = main[ArrayMaximum(main, 0, WHOLE_ARRAY)];

Como criar um oscilador

handle = iMACD(NULL, PERIOD_CURRENT, 12, 26, 1, PRICE_CLOSE);

Ou qualquer outro oscilador que você precise.
