This will be constantly improving. this is the new code that works with BTCs higher price: (copy and paste and no need to add tabs to this one)

//@version=3
study(title="buybuypig timming when things are happening")

//get the last smaller price to set the mtiplier for the scale
adjsc_temp = close<open?close:open//adjusting_scale
adjsc = adjsc_temp<.5?.5:adjsc_temp
//function
showmetime(hours,minutes)=>hset=hour==hours,mset=minute==minutes,[hset,mset]

//default is 14 hours and 30 minutes but it can be adjusted
hourtoadd1 = input(14, title="Hour A")
minutetoadd1 = input(30, title="Minute A")
// //default for the minutes B
minutetoadd2 = input(45, title="Minute B")

[hset,mset]=showmetime(hourtoadd1,minutetoadd1)
plot(hset?.5adjsc:0)
plotchar(hset?minute==minutetoadd1?true:0:0, text='H A', location=location.belowbar, char='A')
