I want something to alarm me at the end of each bar, specifically 15 min, but I am using 1 min so I can test it. It seems if I mention a function like Seconds from Time or GetTime, it does not work the alarm or sound alert at all. declare once_per_works with a true statement but the ticks come at any time in the time interval. These are methods I have tried. Could you give a hint. I remember in being easy in MTL4, and NinjaScript. #TimeAlert declare once_per_bar; #Method 1 input MinNo=15; def BarTimeCount=GetTime(); # (in milliseconds) def AlarmBarCount= GetTime() + MinNo*60*1000; #milliseconds
def Alarm= BarTimeCount[0] >= AlarmBarCount[1]; AddLabel(yes,”BarTimeCount is “+BarTimeCount is “+AlarmBarCount+ “AlarmBarCount,Color.DARK_GREEN);
#Method 2 def DaySecPST= SecondsfromTime(2100); def TFSec=MinNo* 60 *1000; def Alarm= if DaySecPST/TFSec- Floor(DaySecPST/TFSec) <= 60000;
#def Alarm= if SecondsfromTime(2100)/ TF*60*1000- Floor(SecondsfromTime(2100)/MinNo*60*1000) <= 60000; AddLabel(yes,”DaySecPST is “+DaySecPST+”Floor DaySecPST is “+Floor(DaySecPST,Color.DARK_GREEN);
#Method 3 def Alarm= RegularTradingEnd(GetTime())/MinNo*60*1000 – Floor(RegularTradingEnd (GetTime()) /MinNo*60*1000) <= MinNo*60*1000;
#Method 4 cum= cum[1]+1; def Alarm= if (cum/TF)- Floor(cum/TF) =0 then 1 else 0;
#Method 5 declare once_per_bar; Alarm==1; Alert(Alarm, MinNo+” Min Alarm”, Alert.Once, Sound.Bell);

I am a bit confused. You posted this in the “Alerts and Notifications” topic. Your request is to be alerted at the end of each bar. Yet the first three of your examples do not use the Alert function at all. The first three make use of the AddLabel method. Which has nothing do to with alerts. So I’m going to provide my solution to the Alert part of your question. No chart labels. The solution may be much simpler than you realize. We can set an alert, one that triggers on every bar. We set that alert to tigger once per bar.
I have not tested it. But I think it should work. Marked as spam

This is now the entire program: #ADLTimeAlert declare once_per_bar; input MinNo=1; #######################ALERT####################################

So you got things working as you requested? Not sure why you are still adding the statement “declare once_per_bar” as this is already implied by the alert type: “Alert.BAR”. |
Crazy, I could not get not get anything to alarm on Sunday. True the redundancy or the declare statement and the Alert.Bar might have caused the problems. I was trying so many things. Anyway sound an alert is working as before, but again it is not exactly every minute- sometimes it is 70 seconds, sometimes 51 seconds as I have it on a 1 min/60 sec chart. I could swear the variation was more, but I guess 19 % +- is not that bad.
Originally, I was looking for less than %5. I can see in my messages the recording of the alert and time, and it at a low 00 in the minute and a high 19 in the minute range.
If there is way getting less variation, let me know. Otherwise, I will mark it as resolved in 2 days.

Now that I understand what you have been expecting to achieve I have some great news for you. Give up. You will never get there with Thinkorswim. This is because Thinkorswim uses a data aggregator for the streaming quotes. You will never have a one min bar close at exactly 60 seconds on Thinkorswim. The data comes through in buckets. Not for every single tick. If you want something that will sound an alarm at the end of every 60 seconds. Go buy one. I mean go by an application or a piece of hardware. Don’t rely on the data feed of a trading platform and expect to make this happen. |

Just tried it on 5 min. It really is at most 19 seconds on that too. I should have realized it is will be a much smaller % on the 15 min. Really just amazed at that all the time-related function/ methods I tried, did not work at all. |
It is resolved. Probably that is why the Time-related functions I used seemed to shut the alert off.

Sorry, assumed it. I am using this as the alert paragraph.
Alert(Yes,MinNo+” Min Alarm”, Alert.Bar, Sound.Bell);
Alert(Alarm,MinNo+” Min Alarm”, Alert.Once, Sound.Bell);
Alert(Alarm,MinNo+” Min Alarm”, Alert.Once, Sound.Bell);
So I do have Alert.Bar-and not Alert.Once in one of them. I have changed them all to Alert. Bar but does not work.
Did you try my solution then? Set alert condition to yes. It always triggers. For every bar. It is set to Alert once per bar. So instead of alerting at the close of the bar it alerts at the beginning of the new bar. Which is just milliseconds apart.
