Я пытался кодировать линии тренда Гаусса в Trading View. Я продолжаю получать следующую ошибку при попытке сохранить:
"Операция сохранения не удалась, причина: ошибка".
Линии тренда, которые я хочу наложить, это 3, 7, 30, 50, 100, 128 и 200.
Пожалуйста, может кто-нибудь просмотреть мой код и сообщить мне, что мне не хватает?
