Best strategy is the strategy that works for you. The strategy that works for you may not work for me. Every body sees the market differently. For some people it's 5+5= 10 and for some people it is 8+2= 10. Try to understand the market. Read charts everyday. You will find the market sentiment. Start with a single pair. Do not run for ready-made strategies. There is no holigrail. Like trading system, broker is also very important.
