Why is high(sym("$ticki") null after some bars?

[zottl]

This EFS should display a marker for all $TICKIs > 26. When I'm adding this formula on a simple 2min bar chart of $TICK, the high of $TICKI will not longer be evaluated after barindex -608 because high(sym("$ticki") is then always null.

I do not understand why it's null. Can anybody help me, please?

FWIW the formula appears to be working at my end as you can see in the enclosed screenhot
You may want to provide some more details such as the Time Template settings etc so that others can try to test it under the same conditions

hi alex,

I'm in Europe and I'm using a intraday-defaults time template which shows all bars between 14:30 and 21:00. I've set local timezone in preferences. When I look at the formula output window the value for the ticki high shows null after bar -600. The last high ticki marker I see is at 03/09 at 19:56 which is barindex -597. After that I see no more markers allthough the next marker should be at 03/09 at 15:44 where it was 28. Could this be a problem with US summertime? But when I use a time template 00:00 - 24:00 the null appears already at barindex -312. The last marker I see is in this case at 03/11 20:34. Very misterious....

What timezone? Also is the Time Template set to Dynamic or are you loading a specific number of bars or days?
You may want to post an image of the Time Template or of the entire chart showing the description [displayed in the top left corner] which includes the Time Template settings

hi alex,

my windows timezone is set to central european time(vienna). My eSignal timzone is normally set to local but I've also tested the exchange timezone in preferences as you can see in my screenshot but always the same problem. After several bars the value for $TICKI will be null in the formula output window. My time template is set to dynamic.

That happens because you have the Time Template set to Dynamic which means that it will initially download enough bars to fill the chart (300 is the default minimum) and an equal amount of data for the external symbol
If you then scroll back the chart it will request additional data for the symbol in the chart but it does not generate a request of additional data for the external symbols called by the efs hence the nulls prior to a certain bar
The solution is to set the Time Template to load a predefined number of days or bars. For information on how to use Time Templates see this article in the eSignal KnowledgeBase
By the way this issue is similar to the one you and I discussed in this thread
