There is no reason to disallow questions on technical analysis. It is certainly within scope for an individual, non-professional investor.
Whatever opinions we have on its utility, efficacy or what-have-you have no bearing on this discussion.
As I recall, we've discussed the basic principle that if an individual investor can do it, they should be able to ask about it here.
I think that they should be able to ask some basic questions about any financial product/topic, regardless of scope. At the very least, asking for a definition shouldn't be an issue. They may very well see enticements for such financial products and wonder if they are appropriate for their goals. If said product is out-of-scope for personal finance, we can close, but keep some of those questions around to answer future questions and to demonstrate why we believe they are off-topic; since answers should have some discussion as to why they are not appropriate for personal finance.
Regarding this question, its real problem is naïveté.
The question isn't very broad. It's asking for the time ranges involved:
day trading: generally, within 1 day
swing trading: 1-4 days
position trading: 1 week - 1 month
Again, the problems is naïveté. Much more discussion is required to do justice to the topic. However, answering the question asked is a simple matter.
