Can you build range/renko bar charts outside of market hours

So I would like to do some visual testing this weekend before market opens using range or renko bars, but I remember in the past you had to build them during mt4 market hours or nothing will happen. Is there any way these days to get a build of a few days at least before market open ?

thx

My Renko chart builder works during the time that market is closed (e.g., weekends). You can download it from the following address:
