To project the future? I can see the movie-rights changing hands, any day now … 
Indicators are not bad, if used properly 
but it takes time to find the best combination.
That really depends on the person, but if one does decide to use more than three indicators it’s a good idea to place them on different charts, rather than all in one chart.
What indicators show, is the past and the present. You can you use the indicators to have a picture about how the market moved. The chart (candle sticks, bars, areas, …) is a picture of the market.
So, how you look at the market is a matter of preference.
Can be also useful when looking for pullback.
Hi grozny
Using same indicator on different timeframe would be relatively correct. You can’t compare apple and orange.
0 indicator is pure arrogance
1 indicator is great
2 indicator would be nice
3 indicator may boost confidence
4 indicator personally i start to get dizzy
Ema rsi macd pivot indicator can be very useful
When use appropriately
I wouldn’t call trading with no indicators arrogance. Some people prefer trading with pure price action and no indicators, and they are successful. It really depends on the individual.
