How to use exit time in comparison like >,<,=

i am doing mathematical operation in traded instrument (exit time) + X minute and compare it
to with number, but it didn’t work

time condition

Number 999 or 1060 is invalid. Th numbers should be in HHmm (24hour) format for example market opens at 0915 and closes at 1530

hhmm - format works in tradetron

Ex:
Time > Number(921)
Time < Number (1525)
Time == Number (1159)
