Is there a function to tell you the end or start tick of a bar

[xewoox]

I try to match this function in TradeStation Easy Language Function
BarStatus
is used to determine whether the current tick is the opening or closing tick of a bar, or whether it is a tick ’r;inside the bar.’
BarStatus(DataNum)
DataNum is a numeric expression representing the data stream that is being evaluated. 1 refers to Data1, 2 to Data2 and so on. DataNum can be between 1 and 50, inclusive.
Notes:

This reserved word will return one of four possible values:
2 = the closing tick of a bar
1 = a tick within a bar
0 = the opening tick of a bar (relevant only for strategies using Open Next Bar order actions)
-1 = an error occurred while executing the reserved word
When used with multi-data charts the data series referenced must be applied to the chart. For example, to use BarStatus (2), a second data series must be applied to the chart.

Hello,

I am not familiar with TS Easy Language, however I think you could use FirstTickOfBar:
