@l-andorrà thank you for your help.

Found my answer here https://fxdreema.com/forum/topic/4546/simple-question-print-objects-multiple-times-on-initialization-of-indicator/3

And modified it a lil bit.

Hi everyone, currently im try to create a live backtest for my indicator, what i'm trying to do is,
1. i want to get all arrow that generated from indicator buffer 0 and 1
2. check it after specific time/candle if price close above or below open price on that signal buffer.
example, if sell signal is appear on candle[20] and i want to check after next 5 candle if price is close below candle_open[20] the logic in my mind is like this :
candle_open[20] > candle_close[16] ( next 5 candle from signal, and i want to start counting from the signal appear, so 20,19,18,17,16)

Question:

1. i'm not sure which function to do that, should i use Indicator is visible or For each Object
2. how to get candle id from that signal ? if i know this one it will be easy to check if price is close above / below signal after specific candle

thank you!
