Update Pine v5 Session Window

I already have the full source of a TradingView indicator written in Pine Script v5. What I need is a concise enhancement: two new user-inputs that let me enter Start Time and End Time in HH:MM format. Once those inputs are in place, every price-based calculation and plot generated by the script must respect that window—anything outside the session should be ignored. Volume logic can stay exactly as it is.

The script is currently able to draw the daily session high/low range; however, it only keeps today’s range onscreen. I want those ranges to remain visible for every past day so users can scroll back and still see them just as they appeared in real time. The existing line style is fine—no change needed there.

Finally, give me a clear visual cue at the exact start and end of each session: both a label and a small marker so traders can spot the window instantly.

Deliverables
• Updated .pine file with the two time inputs, session-bounded price logic, persistent historical ranges, and both labels and markers in place
• Brief comment block at the top summarising the new parameters and where you touched the code
• Confirmation that the script compiles and plots correctly on any chart timeframe in the TradingView editor
