Помогите подредактировать код ,чтобы показывал только негативные изменения.

негативные изменения? это понятие ра-а-а-стя-я-я-жи-и-мое-е-е. :)

а что означает в коде слово"negative"?

Код, помогающий понять алгоритм постороения RSI уже выкладывался в ветке Один эксперт у одного брокера на разных терминалах и счетах, результат разный
