Open-Close Price Difference

2 ก.ย.Input time A (open time) and time B (closing time)
do not do anything with the year-month-date, it's there because I don't know how to fix it and it needs to be in such format.

the difference of price will be shown on the indicator window one candle after the closing time (opening at such time)
