why are these dates and times adding vertical lines in the future on tradingview?

Question

i am trying to a add these dates and times on to a Tradingview chart - it appears that they are on the chart but not at correct times and dates, they are after May 24th, which is the future!

Any ideas or fixes would be very helpful!

using this code works just perfect, only thing thats different i believe is the length and amount of dates and times

study("Economic News Vertical Lines", shorttitle="Econ News", overlay=true)

// Define event times (PST, UTC-7)
event1 = timestamp("2023-05-22T00:01:00")
event2 = timestamp("2023-05-22T00:50:00")
event3 = timestamp("2023-05-22T14:00:00")
event4 = timestamp("2023-05-22T23:00:00")
event5 = timestamp("2023-05-23T00:30:00")
event6 = timestamp("2023-05-23T05:00:00")
event7 = timestamp("2023-05-23T06:00:00")
event8 = timestamp("2023-05-23T06:59:59")
event9 = timestamp("2023-05-23T07:15:00")
event10 = timestamp("2023-05-23T07:30:00")


// Function to draw vertical lines
draw_vertical_line(time_event, color) =>

    line.set_xy1(p, x=time_event, y=lowest(low, 500))
    line.set_xy2(p, x=time_event, y=highest(high, 500))

Answer 1

try changing your study call to this. The default number of lines pine draws is 50 so all of your earlier event lines get deleted
