convert metatrader indicator to ninja for me.

[simpletrades]

This a great indicator i found on metrader where i trade forex, but would like to use it on ninja with futures.
It was written and posted by a Russian and this was his English version, but there's no documentation and I can understand ninjascript coding somewhat but have no clue with metatrader.
This works well on pullbacks with the trend, except it needs to keep being refreshed each bar for some reason. I would like it to only show on the bar close--easy on ninja.
If it can get coded for ninja so I can understand how it works, I can add filters to eliminate false signals (red dots in an uptrend, green dots in a downtrend and pullbacks that were too shallow).

/* Тут вот та самая оптимизационная фишка. В язык введена функция, которая возвращает количество
посчитанных баров, причём очень хитро. При первом вызове индикатора это 0, всё понятно, ещё ничего
не считалось, а затем выдаёт количество обсчитанных баров минус один. Т.е. если всего баров 100,
то функция вернёт 99. Я ввёл такой код, выше у меня определялась NB - кол-во баров подлежащих
обсчёту. В принципе этот параметр можно и выкинуть, однако для тех кто в танке (I80286) можно
и оставить. Так вот, здесь, при первом вызове NB остаётся прежней, а при последующих уменьшается
до последнего бара, т.е. 1 или 2, ну или сколько там осталось посчитать*/

actually, i was hoping for a reader to help on this--even to just explain how it does work. Is there a different place to post my thread to get that response?
