You can make any time interval on most platforms, the question is what is the point of doing so.
What is the advantage of using a 4 minute over a 5 minute or a 2 minute over a 1 minute.
In my opinion, things work because a lot of people use it, price often respects 100 or 200 day moving average, not because the price knows the moving average is there, just because so many people look at it and react at it when price gets near it.
You are best off using things a lot of other people are also using/looking at, this way you know it will have some sort of value. Most people use 1 minute, 5 minute, 15 minute, ...
If your not careful you end up watching 1, 2, 3, 4, 5, 6, 7, ... and you will get a lot of conflicting signals.
