Визуальные улучшения, которые я добавил в VADER-DEB, помогают лучше понять рыночные действия
Это двойной VADER с энергетическими прутьями
Некоторые могут считать эти изменения незначительными, но, на мой взгляд, они более визуально привлекательны и лучше для
В коде нет изменений в основных расчетах, как показано на графике выше, где мы сравниваем две версии VADER бок о бок.
Если вы довольны VADER v3.0, пожалуйста, не стесняйтесь продолжать использовать его.
Удачи!
