I try to build an indicator to get the ranges of candles by the same day of week, hour and minute, then to compare the current candle range with the average.
I use last_bar_time to get the bar time of last candle displayed by the chart.
When the engine loops through bar_indexes from 0 till the end, if the dayofweek, hour and time are matched with last_bar_time details, store the values in an array.

At first iteration of script it works ok, but when i play Next candle in replay or is a new candle in realtime, data is not updated in array.

I attached code where i store candle details (day hour min) and is not working ok. Thank you.

indicator('Ca Range', "Ca Range", overlay=true, max_lines_count=500, max_boxes_count=500, max_labels_count=500 ,  max_bars_back = 4999 )
