PineScript: Generate an alert on the very first bar of the day

I am trying to generate an alert on the opening bar of the day with the previous closing value.

So my code is something like:

lastPrice = barstate.isrealtime ? close[1] : close
message = "My beautiful alert message of previous close price: " + str.tostring(lastPrice)
if (barstate.isfirst) 
    alert(message, alert.freq_once_per_bar)

I am in Daily chart.

However none of the alert is generated in 9:15 AM when the Indian market opens up.

So my expectation is:

At the very first minute of the market open (say 9:15 AM), I want the alert message to be fired up.

I put the alert message setting something like this:

barstate.isfirst will return true only for the very first bar on your chart.

If you want to detect the first bar of the day, use something like below:

is_first_bar = ta.change(time("D"))
