I can't get the value of lower timeframe

[Berk Cetiner]

Hello, i am using the icustom function to get values for current and lower tf but when i test it with strategy tester it is getting the value of current timeframe but i can not get value for lower time frame such as 5 min. Can someone help me to fix my problem, thanks

do you get an error when compiling this code

Nope, it is compiling without error. I copied only the part of icustom function and didnt copy the rest of code because it could be long.

Maybe this happens because there is a lack of history data in lower timeframe thats why i couldnt get the value for lower time frame because in backtesting if i set near date to current date, it gives value without error.

Do you have an idea or suggest to fix this issue? 

Thanks
