To get the best out of any analysis confluence between multiple tools is best because it gives a clear picture of where to possibly set take profit and set a stop loss in case of reversals. For me i Iove support and resistance and so I combine trend lines, moving average, time frame and indicative candle stick making sure my chart is as neat as possible and any signal outside this i avoid it. This keeps my trading discipline in check.
What are your own it can be beneficial to someone else.
Making your chart as clean as possible but i do agree that no matter how many indicators or tools that you are putting on as long you could
able to read and make analysis from it.
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.
