    Да, через пандас. Вроде бы все просто, но у меня уже голова лопается от нагрузок разного рода, поэтому на объединение уже просто мозгов не хватает. 🙂 Всего 7 DF разной длины. 

    ДФ содержит название валютной пары, время открытия бара, цену, и другие столбцы.

    Примерно нужно так сделать:

    Если EURUSD в первом DF == EURUSD во втором DF
    и час открытия бара в первом DF == Часу открытия бара во втором DF:

     Добавить строку с данными из второго ДФ в первый

    Иначе - пропустить данные


    Куда скинуть пример?

    Спасибо, но такая реализация, как и с ключами не работает.. 

    с ключами пишет ошибку памяти, а метод outer соединяет не так, как нужно..

    outer удлиняет ДФ1 на длину ДФ2..
