What timeframe is best for scalping

[GreatArkansas]

Some say 15 mins and I agree with them but for me, 1 and 5 mins are better for scalping.

Then it's much better if you look for all the time frame before entering, like for example if you are mainly using 15 minutes time frame, then before you entry wait for some confirmation on the lower time frame, like in 5 minutes time frame or much better 1minute time frame.
It's just needed so much time when doing scalp trading, but if you have patience, it is also good.
