Create vertical line at X hours ago that works on tick charts- is it possible?

[Glefdar]

I normally use a vertical line script to mark the point of 3 hours ago on my charts. I adjust the number of bars back that the vertical line will be painted, based on the aggregation of the candles.

(Eg. if wanting the line to mark one hour ago then it would be 60 bars ago on a 1min chart and 4 bars ago on a 15m chart. Although it might be 61 and 5, because the vertical line appears to the right of the current bar, not the left - I can’t remember offhand if the input for the script needs to be the time back +1 bar because of that, but you get the idea.)

I do this so that I can immediately spot which portion of each chart’s candles corresponds to the candles on the other charts using different periods, without needing to inspect the x-axis time labels of the chart cells. It’s helpful when using a lot of charts having different periods across different flexible grid cells.

However, using an adjustable bars back input or counter for drawing a vertical line X hours ago obviously won’t work on tick charts. Is there a way to do it on tick charts? I think probably so using “secondsfromtime” or something but it’s not clear to me how. Also I am not sure if some time functions might not work on tick charts since they can’t reference secondary periods but maybe that is irrelevant. I think that Welkin’s volume tick projection study draws bars at set time intervals on a tick chart, if I’m not remembering wrong, so an answer/ solution might partly lie there.

I would be very grateful if anyone has a solution for getting a time marker based on X hours ago to work on a tick chart.

To clarify this is the post with Welkin’s code that can access seconds on a tick chart, which is what made me think it’s possible to do what I’m wondering about:

I have something that may work for you, but I can't test it on a Saturday afternoon. I'll work on it when trading is live and get back to you.

This might work

#Vericalline_x_hoursback_TickChart_using_Gettime

input hoursback = 3;
input test = yes;
def hour   = 3600000;
def lastbartime = if !IsNaN(close) and IsNaN(close[-1]) then GetTime() else Double.NaN;

#Current Bar
AddVerticalLine(GetTime() >= HighestAll(lastbartime) and GetTime()[1] < HighestAll(lastbartime), " ", Color.WHITE);

#Bar x_hoursback from Current Bar
AddVerticalLine(GetTime()[1] < HighestAll(lastbartime - hour * hoursback) and GetTime() >= HighestAll(lastbartime - hour * hoursback), " ", Color.WHITE);

#Test
AddChartBubble(test and (GetTime() >= HighestAll(lastbartime) and GetTime()[1] < HighestAll(lastbartime) or GetTime()[1] < HighestAll(lastbartime - hour * hoursback) and GetTime() >= HighestAll(lastbartime - hour * hoursback)), high, GetTime());

This might work

Wanted to let you know that I just tried your solution and it works great, thank you!

I added "declare once_per_bar" to potentially improve the efficiency as well and have used it to replace my version which required manually counting back bars, since that would not always work correctly if bars were missing on a time chart for any reason such as low liquidity.

"declare once_per_bar" is not a working ToS function
