Based on my own experience this is what i do commonly use.
1. Support and Resistance
2. Trend Lines
3. MA
4. RSI
5. Sticks on hour timeframes and finding out some bias.
This is actually basing on your own preference on what suits you on.
This can be a good indicators to use every time you trade, it compliments the other indicators and you can get more effective result if you do follow these indicators. I've been using a lot of indicators lately because the market is not moving that much and its hard to get the correct data if you are just going to base on a single tool. Knowing the best indicators to use is a must, you should focus on that and learn how to create a good strategy using that indicators.
