Time frames and s/r history?

Hello again,
Can somebody please tell me how far back i should go on these time frames
to look for support and resistance area.
15min 1hour 4hour and 1day chart.
How many candles should i have on my chart for each time frame.
I will only use candlestick patterns and s/r . No indicators.
As a beginer, is there a particular time frame that is better for me to work on to gain experience.

Thanks in advance.
