What would you suggest the best time frames to trade in. I was thinking linking the 5min Chart with the 15min chart.
I would recommend a beginner goes for multi-day trading. Day-trading is too fast and too difficult: it doesn't allow you time to develop or learn.
If you are a really good trader, time-frame won't matter.
It depends with what trader you are. If you are an intraday day then you should have a look on a daily timeframe and then on a 4-hour and 1-hour chart. Medium-term trader will follow the weekly chart and long-term traders the monthly timeframe.
